<P>PROBLEM TO BE SOLVED: To provide a silencer for a rotation limit device that can effectively eliminate a crash sound generated by a stopper member without making the movement of two rotating bodies unstable. <P>SOLUTION: The silencer includes cushioning members 31 protruding on groove side surfaces of a first guide groove 11 and a second guide groove 12 which are parallel with a moving direction of the stopper member 21 at stop positions 11A, 11B, 12A, 12B, and when the stopper member 21 runs into groove end surfaces of the first guide groove 11 or the second guide groove 12, reducing the kinetic energy of the stopper member 21 by making contact with a surface parallel with the moving direction of the stopper member 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
