Abstract:
1. A drive force transmitting apparatus for a vehicle comprising: a drive source; a drive force transmitting path adapted to be connected to a drive shaft to transmit a drive force from said drive source to said drive shaft; a clutch mechanism capable of connecting and disconnecting said drive force transmitting path; a parking mechanism provided in said drive force transmitting path and capable of stopping the rotation of said drive shaft; and an actuator mechanism capable of selectively operating said clutch mechanism and said parking mechanism, wherein said actuator mechanism comprises a rotating shaft to which a cam portion and a parking pivot portion are fixed, a power source for pivotally rotating said rotating shaft, and an operating fork adapted to be moved by said cam portion for operating said clutch mechanism, said cam portion being inserted in a U-shaped recess of said cam follower connected to said operating fork, said clutch mechanism is selectively engaged and disengaged by touch of said cam portion and said U-shaped recess of said cam follower based on rotation of said rotating shaft to thereby move said operating fork, said parking mechanism includes a parking pawl adapted to be pivotally rotated by pivotally rotating said parking pivot portion together with said rotating shaft and a parking gear fixed to said drive shaft, said parking pawl being engageable and disengageable with said parking gear only by rotation of said rotating shaft, said cam portion is formed so that said cam portion touches said U-shaped recess of said cam follower when said rotating shaft is rotated so as to operate said operating fork, and said cam portion is formed so that said cam portion does not touch said U-shaped recess of said cam follower when said rotating shaft is rotated so as to operate said parking mechanism.
