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.

Abstract: Provided is a power seat operation device configured so that movable mechanisms can be selectively operated and so that a movable mechanism which rotates and moves a movable section can be intuitively operated without impairing the intuitive nature of operation of a movable mechanism which linearly moves a movable section. A power seat operation device (100) is configured in such a manner that, when a dial member (128) is rotated and operated, a movable mechanism which is to be operated is selected from among movable mechanisms. When a switch member (130) is rotated and operated, the selected movable mechanism is actuated. Also, the switch member (130) is rotated and operated about a rotation axis (H) extending in the widthwise direction of the seat. This means that the direction of operation of the switch member (130) can be aligned with or nearly aligned with both the direction of the actual movement of a seat back (120) when a recliner mechanism (122) is actuated and the direction of the actual movement of an ottoman (124) when an ottoman mechanism (126) is actuated. Also, in a state in which a seat slide mechanism (108) is selected, the direction of the operation of the switch member (130) is aligned with the front-rear direction of the seat.

Abstract: A power transmission member that transmits rotation of an output shaft to a movable mechanism achieves a simpler structure and increased productivity compared to when a conventional flexible cable is employed. Out of plural output portions 30 of a clutch unit 2, power transmission members that transmit rotation of an output shaft 31 to a movable mechanism are configured by a conventional torque cable in a second output portion 30B and a third output portion 30C. However in a first output portion 30A, the power transmission member is configured by a gearbox 3 including a worm 71 that is coaxially and integrally formed with an output shaft 31A.
