Abstract: Provided is a flexible member that can exhibit excellent load resistance and flexibility while achieving a reduction in size. This flexible member includes: a main body part which has multiple wave washers stacked in an axial direction and joined to each other, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers; and a linking member that is elastically deformable, the linking member being provided at an end part of the main body part and being linked to other member. A deformation amount of the linking member is smaller than a deformation amount of the wave washer, when the main body part is bent.

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: The present invention obtains a multi-shaft drive device that can protect a rack and pinion from operative load input to a selector. The multi-shaft drive device is provided with: an input-side bevel gear (52) to which motor power is transmitted; and an output-side bevel gear (34) that transmits the power transmitted from the input-side bevel gear (52) to a movable mechanism. The multi-shaft drive device is further provided with: a selector (10) that connects/disconnects the meshing of the output-side bevel gear (34) and the input-side bevel gear (52); and a rotating shaft (16) that causes the selector (10) to slide via a rack (18) and pinion (17). Furthermore, the angle of rotation of the rotating shaft (16) is regulated by the end of the pinion (17) contacting a vertical wall (1A) of a case (1).
