A sliding assisting device assists a movable body to move between a drawn-in position and a drawn-out position relative a main body. The sliding assisting device includes a unit main body provided on one of the main body and the movable body, and having a slider, a lock member, and a spring member; and an operating member provided on the other of the main body and the movable body. When the movable body is drawn out to a mid-course position from the drawn-in position or drawn-out position, the operating member displaces the lock member from a locked position to an unlocked position, so that the movable body slides from the mid-course position to the drawn-out position or drawn-in position by the spring member.
