  • Patent number: 9388891
    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.
