IPC: F16D7/02
Filed: 2002-03-20
Abstract: <P>PROBLEM TO BE SOLVED: To prevent noises without using grease when an input member runs idle, in a device in which the input member is joined with an output member by a coil spring, the input member being kept idle relative to the coil spring when the output member is not rotated by the torque of the input member.  <P>SOLUTION: A frictional engagement part K between the outer periphery of the input member 10 and the inner periphery of the coil spring 30 is given an axial taper angle θ so that the axial surface pressure of the frictional engagement part K gets smaller toward the input end of the coil spring 30. When the input member runs idle, the coil spring 30 opens wider in the loosening direction of the spring depending on the taper angle θ as it gets closer to the input end, with the number of open turns increasing, to control noises even without grease.  <P>COPYRIGHT: (C)2004,JPO
