A motor comprises: a shaft; a rotor coupled to the shaft and including a magnet; a stator disposed outside the rotor and including a coil and a stator core; a cover disposed on an upper side of the rotor; and a magnetic sensor disposed between the cover and the rotor, wherein the magnetic sensor is disposed on an upper side of the magnet, a surface of the magnetic sensor facing the rotor is disposed below the uppermost end of the coil, and the length of the rotor in the shaft direction is longer than the length of the stator core in the shaft direction.

A drive unit includes an electric motor, first and second torque transmission paths, a torque converter, first and second gear trains, and a first switch mechanism. The first and second torque transmission paths are provided parallel to each other. The torque converter is disposed in the first torque transmission path. The torque converter amplifies a torque outputted from the motor when the torque is directed in a first rotational direction. The first gear train is disposed in the first torque transmission path. The first gear train is disposed downstream with respect to the torque converter. The second gear train is disposed in the second torque transmission path. The first switch mechanism switches between the first torque transmission path and the second torque transmission path as a path for transmitting the torque outputted from the motor.

An actuation assembly for use in a drive unit assembly of a vehicle. The actuation assembly includes an actuator shaft that is connected to a shift shaft and a shift fork via a lever member. At least a portion of the lever member is connected to the shift shaft and at least a portion of the lever member is pivotably connected to said actuator shaft. An actuation mechanism drives the actuator shaft linearly to pivot the lever member which in turn rotates the shift shaft and the shift fork.

There is provided a shift device for a straddle-type vehicle that is configured to cause a transmission device to perform a shift change in accordance with rotation of a shift shaft. The shift device includes: a shift lever provided with an operation portion that is configured to receive a shift operation; a shift sensor provided on the shift shaft so as to be integrally rotatable with the shift shaft; and a shift rod that couples the shift lever and the shift sensor. The shift sensor is configured to detect the shift operation on the shift lever in accordance with a movement of the shift rod. The operation portion and the shift sensor are positioned at the same side in a manner of sandwiching the shift rod.

An object is to reduce a delay in response. An automatic gear changing control device includes a sleeve which is moved by an actuator to perform an engagement operation, an engine which is connected to an input shaft, and a control unit which controls the movement of the sleeve by the actuator and controls the rotation of the input shaft by the engine or a motor generator. The control unit performs synchronization control of controlling the rotation of the input shaft for the engagement operation at a different gear stage after the engagement is released and starts shift control of moving the sleeve to an engagement completion position by the actuator before at least the synchronization is completed.

A shift signal transmitter for a manual transmission of a vehicle, in particular of a motorcycle, includes a shift rod for force-transmitting coupling to a foot lever, optionally with the interposition of an extension rod. The shift rod is guided along its longitudinal axis in an axially displaceable manner between two axial stops in an, in particular sleeve-shaped, housing. A connecting piece, which serves for coupling to a shift lever, is rigidly connected to the housing opposite to an internal axial end of the shift rod. A distance sensor for contact-free distance measurement is disposed within the housing opposite to the internal axial end of the shift rod and a sensor area of the distance sensor is oriented radially relative to the longitudinal axis. A shift apparatus for a manual transmission of a vehicle is also provided.
