In order to avoid competition with other components for a space, to thereby improve the degree of designing freedom, the power transmission apparatus includes a transfer case housing and supporting a ring gear and a pinion gear that orthogonally mesh with each other and form an orthogonal gear set, the transfer case is divided into a first case part and a second case part along a division plane that extends along an axis of rotation of the ring gear, and the first and second case parts and are fixed together along the division plane with bolts.

A reduction drive device is compact, hardly causes an electric motor thereof to vibrate, and has improved noise/vibration controllability. The reduction drive device includes the electric motor attached to a casing and capable of outputting torque, first and second reduction mechanisms supported by the casing, to reduce and transmit the rotational output of the electric motor, and a rear differential supported by the casing, to distribute the rotational output reduced by the first and second reduction mechanisms to a pair of axle shafts. Rotor, stator, and brush of the electric motor partly overlap the rear differential when seen in a rotation radius direction.

A wet type friction clutch and an electromagnetic clutch is disclosed wherein a pilot clutch is disposed in a magnetic flux path of an electromagnet and is kept between an armature and the electromagnet . Upon excitation of the electromagnet , the armature is retracted to allow the pilot clutch to be coupled. The pilot clutch includes a plurality of clutch plates which are interleaved with respect to one another for sliding movements. Adjacent clutch plates A, B, A, B, C, D, E, F are formed with oil guide passageways to create a hydrodynamic pressure effect to allow the clutch plates to be separated with a limited drag torque. Further, the clutch plate has magnetic flux path forming portions , at inner and outer peripheral sides, between which through-bores are formed to allow bridge portions to be intervened between the through-bores, with each of the bridge portions being configured such that opposing walls of the bridge portions of adjacent clutch plates have reduced contact surface areas to eliminate a leakage of a magnetic flux.
