Abstract:
A one-way clutch comprising:a first rotation member that has a working surface of circular cross section formed in an outer periphery thereof and is coupled to one of drive and driven sides; a second rotation member that is assembled with the first rotation member so as to rotate around the central axis of the working surface of the first rotation member and is coupled to the other of the drive and driven sides; a shaft member that is disposed radially outside of the working surface of the first rotation member to extend in parallel with the central axis of the working surface and is held at both ends thereof by the second rotation member; a rocking member that is placed radially outside of the working surface of the first rotation member, has a working surface of arcuate cross section formed in an outer periphery thereof and is supported for rocking motion on the shaft member; a friction member that is looped between both the working surfaces of the first rotation member and the rocking member to create two spans between the first rotation member and the rocking member; and a biasing member for tending to rotate the rocking member around the axis of the shaft member so that the rocking member presses one of the spans of the friction member, wherein both the ends of the shaft member are held by the second rotation member through respective support members that each cover side and end surfaces or at least the side surface of the corresponding end of the shaft member on member, wherein both the ends of the shaft member are held by the second rotation member through respective support members that each cover side and end surfaces or at least the side surface of the corresponding end of the shaft member, and wherein the second rotation member is made by die casting, and the support members are insert molded in the second rotation member.
