<p><P>PROBLEM TO BE SOLVED: To provide a compact drive force forward/reverse switching device with an input shaft and an output shaft arranged in parallel. <P>SOLUTION: An intermediate bevel gear 5 is meshed with an input gear 3 fitted in a fixed shaft 1, and an output gear 4 is meshed with the intermediate bevel gear. A transmission sleeve 24 is provided on a control gear 7, and the transmission sleeve is engaged with an intermediate shaft 2. The output gear 4 comprises an output bevel gear part 16 and an output spur gear part 15, and a one-way clutch 6 is interposed between the transmission sleeve and the output spur gear part. A lock releasing pin 23 of the one-way clutch is provided on the output bevel gear part 16. When forward rotation is input to the input gear 3 with the control gear 7 locked by action of an actuator 8, the output bevel gear part rotates forward, and the one-way clutch becomes free, and the output bevel gear part and the output spur gear part are integrated and output forward rotation. When the forward rotation is input with the control gear in a free state, the transmission sleeve 24 rotates reversely together with the intermediate shaft 2, and the one-way clutch is locked and reverse rotation is output. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
