<p>In an engaging means (60), a roughly U-shaped engaging part (63) of a slide member (42) sandwiches, along the diameter direction of the axle section (621), an axle section (621) of a pin (62), which is formed in standing state on a base-end face (61) of a force-applying member (50) and has a head section (622) the diameter of which is larger than the axle section (621). Steps (64) along the thickness direction are formed on the engaging part (63) such that at least a portion of the engaging part (63) will come in contact with the base-end face (61) of the force-applying member (50), and such that at least a portion of the engaging part (63) will come in contact with an end face (622A) of the head section (622).</p> |
