A device or arrangement of parts for electrically loading a movable member so as to bias same in one direction. In this device, an elastic member is secured to a pivot provided on a base member, with its two arms being deflected and then held by first and second locking members, after which a movable member is forced down against the elastic member from above, so that a guide portion of the movable member may push one arm of the elastic member so as to keep the arm apart from the locking member which locks the arm, and then a locking portion continuous with the guide portion, of the movable member locks the arm. As a result, the movable member is elastically loaded so as to bias in one direction, while the movement of the movable member is limited by means of a control member provided on the base member.
