<p>PURPOSE:To enable arrangement even if space in an axial direction is small. CONSTITUTION:The mechanism is provided with a friction plate 20 interposed between two rotary bodies 16, 17 and a press-contacting spring 21 by which one rotary body 16 is brought into press-contact with the other rotary body 17 via the friction plate; the press-contacting spring is made of a leaf spring material, and a center plate 21a, which is attached to a shaft 18 supporting the two rotary bodies, and plural arm pieces 21b, which are set protrudingly from the edge of the center plate, extended along the periphery of the center plate and are bent at each tip so as to shift towards one rotary body, are integrally formed. Since the press-contacting spring 21 is formed with the leaf spring material, the dimension of the mechanism in the axial direction is made small.</p> |
