<P>PROBLEM TO BE SOLVED: To provide a reverse cutoff mechanism improved in coil spring durability. <P>SOLUTION: The reverse input cutoff mechanism includes: a fixed side member 2; an input side rotational member 4 rotatable to the fixed side member; an output side rotational member rotatable to the input side rotational member and the fixed side member; a coil spring 8 arranged facing each peripheral surface of the input side rotational member and the output side rotational member; and a braking force giving means giving a braking force to a rotation interlocking with the rotation of input side rotational member of the coil spring. The braking force giving means is constituted such that a braking force giving member is slidably arranged in the circumferential surface 34 of the fixed side member so that the means is engaged with the coil spring, and that the braking force is given to a rotation to the circumferential surface of fixed side member of the braking force giving member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
