PURPOSE:To arbitrarily control the automatic traveling speed of a traveling member by a pulling-out force and permit the automatic traveling within an arbitrary set range by setting the position of a lock means by installing a locking means, etc., which can lock a traveling body on a fixed rail. CONSTITUTION:Traveling bodies 6 and 6 are engaged in free sliding on the fixed rails 3 and 3. A spring means 7 for applying a pulling out force to the accommodation direction, traveling control means 8, and a lock means 9 for locking the traveling bodies 6 and 6 at the pulling-out positions are installed. A lock plate 25 is built in the traveling body 6, and the lock plate 25 is formed in inclination by a desired angle sideways so as to be turned by 90 deg. by the engagement and disengagement of an engagement pin 33 which is projectingly installed from the rear edge of a slide rail 4, in an engagement groove 27. Further, a stopper 35 is projectingly installed so that the traveling body 6 stops at a prescribed pulling-out position. Accordingly, automatic operation within an arbitrary position range is permitted by properly setting the position of the lock means. |
