PROBLEM TO BE SOLVED: To provide a structure enabling reduction in the production cost of an anti-rattle spring integrally manufacturable by bending a metal wire, favorable in assembling performance, and capable of obtaining a stable elastic force. SOLUTION: The anti-rattle springs 13a, 13a are formed in closed rectangular frame shapes. A first engagement part 24 is engaged with the inner peripheral surface intermediate part of the projecting plates 18a, 18b constituting a support 2a. A second engagement part 25 is engaged with the end outer peripheral edge of a pressure plate 22. A pair of extraction prevention parts 26a, 26b connecting these first and second engagement parts 24, 25 to each other are engaged with both side faces of the both projecting plates 18a, 18b without any gap. Also, both the extraction prevention parts 26a, 26b are bent to obtain an elastic force thereto in the direction in which the first and second engagement parts 24, 25 approach each other.
