Abstract: Weight reduction and space reduction can be performed by using a mechanical clutch having a simplified structure for driving plural output shafts by one motor.
Output gears 21 are disposed so as to be movable toward and counter to plural second input gears 14 to which rotation of the motor 10 is transmitted, and so as to be biased toward the plural second input gears 14. A cam 41, which has plural recesses 42 provided at the periphery thereof, is disposed at the inside of the output gear. The cam 41 is rotated, and a pin 24 of the output gear 21 enters the recess, so that the output gear 21 is moved toward the second input gear 14, and the output gear 21 is engaged with the second input gear 14.

Abstract: A multi-shaft drive device is provided that is capable of obtaining an appropriate backlash in an enmeshed state of an output side bevel gear and an input side bevel gear. An output side bevel gear (35) that is biased in the direction of an input side bevel gear by a coil spring contacts a shaft support bush attached to a wall portion (17) in an enmeshed state with the input side bevel gear. A bias direction stroke end of the output side bevel gear (35) is accordingly restricted. Moreover, the wall portion (17) is provided to a gear holder (15) fixed to a device case (10) that supports the input side bevel gear, thereby enabling the axial direction position of the output side bevel gear (35) to always be positioned at a uniform position to enmesh appropriately with the input side bevel gear.

Abstract: Force of used spring can be weak, wear amount of power transmission member (gear or the like) can be reduced, and generation of strange noises can inhibited.
When the dial cam 50 is rotated and the recess 51 of the outer peripheral surface 52 faces the front end portion 32a of the pin 32 of the connection shaft 31, the connection shaft 31, which is biased by the force of the coil spring 40, is connected to the bevel gear 35, which engages with the bevel gear 14 and is rotated, via the clutch teeth 33 and 36. Thus, the connection shaft 31 is rotated, and the output shaft 20 is rotated together with the connection shaft 31. That is, the power of the motor 10 is transmitted to the output shaft 20. Since the coil spring 40 is used for connecting the connection shaft 31 to the bevel gear 35, the force of the coil spring 40 can be reduced.
