In a shift lever device, a lock bar is disposed in a restricting position to restrict changing of a shift position of a lever. A motor is driven to rotate a cam in order to move the lock bar to a non-restricting position, thereby permitting changing of the shift position of the lever. The lock bar is moved as the rotation position of the cam is changed. This enables the precision required of the rotation position of the cam in order to dispose the lock bar in the restricting position and the non-restricting position to be lowered, thereby enabling appropriate switching between restriction and permission of changes in shift position of the lever to be performed by driving of the motor.

In a shift device, as a result of lower sliding projections of a lever moving slidingly against lower sliding plates of soft materials, the slidability of the lever is improved. Moreover, as a result of restricting projections of the lever being abutted against stoppers of the soft materials, noise generated when a sliding motion of the lever is restricted is reduced. Additionally, because the lower sliding plates and the stoppers are formed integrally with each other, the structure can be simplified.

A power tool includes a button useful to select a direction of rotation of the power tool. The button can be used to select between forward, reverse, and neutral. The power tool includes a housing which is coupled with an abutment structure which engages with the button. A sawtooth engagement is formed between the abutment structure and the button. The sawtooth engagement can be asymmetric in shape to provide different force vectors depending on whether the button is pushed in a first or a second direction. The sum of the resistive forces can be the same whether the button is pushed in the first or second direction, owing to the asymmetric forces caused by the sawtooth engagement which make up for differences in other internal resistive forces.

A shift device for a boat includes a lever which can be operated about a predetermined axis, and a lever operation suppression mechanism which suppresses an operation of the lever. The lever operation suppression mechanism includes a load applying portions (a first load applying portion and a second load applying portion) which apply different loads to the lever in a first operation period of operating the lever between a neutral position of the lever and a first position corresponding to a forward movement of the boat, and in a second operation period of operating the lever between the neutral position and a second position corresponding to a backward movement of the boat.

A shift-by-wire (SBW) column shifter for a vehicle includes a shift lever configured to be moved to shift gears. A shaft enables the shift lever to rotate the shaft about an axis. A lever detent is coupled to the shaft, enabling the shaft to rotate the lever detent about the axis. A slider magnet is constrained to move along a path, such as a linear path. The slider magnet has a groove that is engaged by a projection of the lever detent. Rotation of the lever detent about the axis is converted into movement of the slider magnet along the path via the engagement of the projection and the groove. A plurality of sensors are configured to output signals indicating a position of the slider magnet along the path to indicate a requested change in operating gear of the vehicle.

At least some implementations of a transmission gear shifter include a first shift member, a second shift member, an actuator, multiple feedback surfaces and a follower. The actuator drives the second shift member between a first position and second position and thereby rotates the first shift member from one of the multiple positions to another of the multiple positions. The feedback surfaces are associated with the first shift member, and the follower is movable relative to the feedback surfaces between a first position and a second position. When the follower is in the first position, the follower is not engageable with the feedback surfaces, and when the follower is in the second position, the follower is engageable with the feedback surfaces and when the follower is in the second position there is relative sliding motion between the follower and the feedback surfaces when the first shift member is rotated.

A shift device includes a knob that is rotated to change a shift position, and an operation mechanism including a motor. At least one of restricting or releasing restriction of rotation of the knob is performed when the motor is driven, further, the shift position of the knob is changed to a specific shift position when the motor is driven. Thus, driving a common motor in the shift device enables at least one of restricting or releasing restriction of rotation of the knob to be performed, and enables the shift position of the knob to be changed to the specific shift position. This enables the configuration of the shift device to be simplified, and enables an increase in the size and an increase in the number of components in the shift device to be suppressed.

A vehicle shifter device for ensuring high safety by suppressing misoperation by a driver. The vehicle shifter device includes a shift lever and a lock plate. The shift lever has a cylindrical lever body, a rod movable in an axial direction in a cylinder of the lever body, and a first lock lever and a second lock lever connected to the rod. The first lock lever is substantially L-shaped in plan view. The lock plate has a first extension portion extending in an X-direction and a second extension portion, integrally formed with the first extension portion, that extends in a Y-direction. In addition, the lock plate has a plurality of concave parts. In the lock plate, the projection height of a convex part between the concave part and the concave part is larger than the projection height of a convex part between the concave part and the concave part.

In a shift lever device, a first facing cavity and a second facing cavity of a lever, and a first facing hole and a second facing hole of a printed wiring board, respectively face each other when the lever is disposed in an H position. Thus, in a state in which the lever is disposed in the H position when the shift lever device is being assembled, the first facing cavity and the second facing cavity respectively face the first facing hole and the second facing hole, thereby enabling the accuracy of relative assembly positions of a magnet of the lever and detection elements of the printed wiring board to be increased, and enabling the detection accuracy of a shift position of the lever to be improved.

An activation apparatus for a transmission of a motor vehicle includes a gear selector that is configured to move in a shift gate to thereby select first drive programs, and an activation device that is connected to the gear selector. Actuation of only the gear selector activates the first drive programs. The first drive programs include a forward drive program and a reverse drive program. The gear selector is configured take up a monostable rest position in the shift gate. Simultaneous actuation of both the gear selector and the activation device activates a second drive program that is different from the first drive programs. The activation device is a spring-loaded switch that is activated by actuating the gear selector.
