Abstract: 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.

Abstract: A fiber reinforced plastic spring which enables prevention of breakage caused by compressive stress is provided.
The FRP spring 1 has a laminated structure (reference numeral 20 in case of three-layer structure, reference numeral 30 in case of five-layer structure) having plural fibers which are different from each other in tensile modulus of elasticity and are laminated. An upper surface of the FRP spring 1 is a surface to which pulsating bending load is applied. An upper side region of each laminated structure 20 and 30, which is upper with respect to the neutral axis S, is a compressive stress region at which compressive stress is generated. A lower side region of each laminated structure 20 and 30, which is lower with respect to the neutral axis S, is a tensile stress region at which tensile stress is generated. Distribution of tensile modulus of elasticity of each laminated structure 20 and 30 is asymmetric with respect to the neutral axis S. In this case, it is desirable that a tensile modulus of elasticity of each layer 23 and 35 which is the surface layer portion of compressive stress generation region be the lowest, and a tensile modulus of elasticity of each layer 21 and 31 which is the surface layer portion of tensile stress generation region be lower than that of each layer 22 and 33 which is the neutral axis portion.-

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.
