ABSTRACT:
A power transfer apparatus1of a four-wheel drive vehicle includes, a clutch, an inversion detector, and controller. The clutch generates an engagement force that effects a driving force output from an engine to wheels of the vehicle via a transmission. The transmission includes the inversion detector23, 27for detecting inversion or non-inversion of a gear-shifting direction of the transmission13. The controller23subjects the electromagnet to energization control such that torque to be transmitted by the clutch is decreased to a target value in accordance with an inversion signal pertaining to said gear-shifting direction detected by said inversion detector23, 27.
