The presently disclosed quick adjust slide knob addresses the ‘Backing-Off’ problem present with various conventional nuts. The quick adjust slide knobs can be quickly positioned along a threaded rod by applying pressure to an exposed surface of a partially threaded nut. When the knob is placed against a work surface and the user releases pressure from the partially threaded nut, the thread pattern on the partially threaded nut meshes with the matching thread pattern on the threaded rod. The device can then be twisted, which will translate the device along the threaded rod, to apply a larger load to the work surface. The threaded rod may include one or more key-ways shaped to allow a locking tab housed within the knob to stop the device from freely disengaging the threaded rod to protect a user from potential injury caused by the fastener unexpectedly backing off and disengaging.

A lock mechanism that is switchable between a locking state in which a movement of an operation member of a working machine is restricted and an unlocking state includes an engagement portion to rotate together with the operation member, a lock body including an engaged portion at its intermediate portion, a lock support shaft that supports the lock body rotatably, and a driving portion that applies a driving force to the lock body. The lock body is moved by the applied driving force to a position in which the engaged portion is in engagement with the engagement portion and a position in which the engaged portion is not in engagement with the engagement portion.

A manipulator mechanism includes a rotary shaft rotatable about an axis extending in a first horizontal direction, an operation member disposed at one of opposite ends of the rotary shaft in an axial direction thereof to rotate together with the rotary shaft, an angle sensor disposed at the other of the opposite ends of the rotary shaft in the axial direction to detect a rotation angle of the rotary shaft, and a neutral return mechanism provided between the operation member and the angle sensor to return the operation member to a neutral position from a post-operation position which is a position to which the operation member has been moved.

A motor control system for use in an electric vehicle includes an accelerator lever operable by a user, a controller configured or programmed to control an electric motor to generate a drive power to drive the electric vehicle, wherein a rotation speed of the electric motor is increased in response to an increase in a first rotation angle in a first rotation direction of the accelerator lever from a reference position of the accelerator lever, and a first torsion spring including a coil portion inside of which a rotation shaft of the accelerator lever extends to apply a first elastic force in a second rotation direction opposite to the first rotation direction. The controller is configured or programmed to perform a control to stop the electric motor upon detecting that the first rotation angle is equal to or greater than a first predetermined rotation angle.

Described is a rotation limitation module for a steer-by-wire steering system. Said rotation limitation module comprises a housing in which a shaft portion is received. Furthermore, a limiter disk by way of a sliding guide is coupled in a rotationally fixed manner to the shaft portion and by way of an external thread is driven into an internal thread of the housing. Provided on the housing are detent geometries and on the limiter disk counter-detent geometries which, for limiting a rotation of the shaft portion in a first rotation direction and a second rotation direction, counter to said first rotation direction, are configured for contacting a respectively assigned detent geometry. A steering wheel module for a steer-by-wire steering system, which comprises such a rotation limitation module, is also disclosed.
