Abstract: PURPOSE: To prevent generation of resonance sound due to vibration between an arm shaft and a dynamo holder by setting an inner diameter of an end part spiral part of a spiral spring to be smaller than that of the other spiral parts to fit it to an outer circumferential surface of a dynamo arm shaft. CONSTITUTION: An arm shaft 5 of a dynamo 4 is inserted to a through hole bored in an installation member 2 of a dynamo holder 1. A spiral spring 6 is wound around the arm shaft 5, one end of it is locked to a lock pin 8 fixed through the arm shaft 5, and the other end is locked to an inner wall of the installation member 2. A tip part of the spiral spring locked to the lock pin 8 is applied to the inner wall of the installation member 2. Spiral parts at both end parts of the spiral spring 6 are formed to have smaller inner diameters than the other spiral parts to be fitted to an outer circumferential surface of the arm shaft 5. When the dynamo 4 vibrates, therefore, the arm shaft 5 and the installation member 2 are strongly held through the spiral spring 6, thereby resonance will not be generated between that and the through hole.
