摘要： A rotation position detection device includes a change drum, a magnetic field generator, and a magnetic field detector. The magnetic field generator is fixed to the change drum and rotates along with the change drum to differentiate an ambient magnetic field. The magnetic field detector is formed separately from the magnetic field generator and fixed to a position at which a magnetic field changes in response to rotation of the magnetic field generator so as to detect the magnetic field and output a signal that depends on the rotational position of the change drum on the basis of the detection result.

摘要： A crankcase includes: a main body portion aligned with a drive motor in a direction perpendicular to a motor drive shaft; and an extended portion continuous with the main body portion and located lateral to a motor housing, the extended portion receiving insertion of one end of the motor drive shaft. A power transmission mechanism that transmits power from the motor drive shaft to an input shaft is located partly in a first region defined by the main body portion and partly in a second region defined by the extended portion and communicating with the first region.
