摘要： A fiber reinforced plastic spring is provided, in which broken pieces can be prevented from being scattered when breaking without using any additional member and variation in load when breaking can be reduced. FRP spring 1 has a layered structure 20 having basic unit 20A consisting of positive direction orientating layer 21 and negative direction orientating layer 22. Orientating directions S1 and S2 of the positive direction orientating layer 21 and the negative direction orientating layer 22 mutually adjacent are mutually intersecting. By appropriately setting an absolute value of orientating angles ¸1 and ¸2 of each layer 21 and 22, fibers in the positive direction orientating layer 21 and the negative direction orientating layer 22 can be entangled mutually, and thus, the spring as a whole exhibits pseudo-ductility in a breakage condition. Elastic modulus and strength available for use as a spring can be obtained and breaking at a resin portion between fibers can be prevented in each layer 21 and 22.

摘要： 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.

摘要： 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.
