<p><P>PROBLEM TO BE SOLVED: To provide a compact device for switching between normal and reverse drive forces with an input shaft and an output shaft arranged in parallel. <P>SOLUTION: The device has an input gear 11, an output gear 12, and a switchover mechanism 13. The switchover mechanism 13 is constructed from a planetary gear mechanism 14, a control mechanism 15, and a clutch mechanism 16. The control mechanism 15 has a control gear 25 capable of selectively having a restrained state and a non-restrained state by an actuator 24. The clutch mechanism 16 has a one-way roller clutch 26 placed between a rotation transmission shaft 18 and a clutch installation section 34 provided on a carrier 23. When the actuator 24 is off, the roller clutch 26 is locked to allow planetary gears 22 to perform only revolution, causing an input of a normal rotation direction A to be directly output. When the actuator 24 is on, the lock of the roller clutch 26 is released to allow the planetary gears 22 to perform only rotation, causing an input of the normal rotation direction A to be output with the direction of the rotation switched to a reverse rotation direction B. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
