<p><P>PROBLEM TO BE SOLVED: To reduce abnormal noises of a clutch coil spring of a one-way power transmission mechanism, when slidingly rotated in a cylinder member. <P>SOLUTION: The one-way power transmission mechanism C comprises an input rotating member having an input cam 22a, an output rotating member having an output cam 24 rotatable relative to the input cam 22a, the cylinder member 25 having a cylindrical peripheral wall 25a encircling the cams 22a, 24 and non-rotatably fixed to a supporting member, and the clutch coil spring 26 stored in the cylindrical peripheral wall 25a and puts at its outer peripheral face in slide contact with the inner peripheral face thereof. Ends 26a, 26b of the clutch coil spring 26 can engage/disengage with/from the cams 22a, 24 to permit the transmission of rotation driving force from the input side to the output side but prevent the transmission of rotation driving force from the output side to the input side. In the cylindrical peripheral wall 25a of the cylinder member 25, a cutout 25a1 is provided extending in the axial direction and opening at one end in the axial direction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
