摘要： PROBLEM TO BE SOLVED: To reduce uncomfortable noises and impulse generated from a reversing lock device when conveying a coaster through a chain to a higher position. SOLUTION: This device is provided with a rod 10 supported at its lower end by a roller supporting member 6 so as to swing, rod supporting member 11 linked to the coaster while supporting the intermediate part of rod so as to axially slide it and supporting that sliding part so as to swing it, 1st coil spring 12 positioned between the lower part of rod 10 and the rod supporting member 11 and fitted to this rod, and 2nd coil spring 13 positioned between the rod supporting member 11 and the upper part of rod 10 and fitted to the rod. When a roller 5 moves over the peak spot of streamlined member and a reversing preventing member 1 jumps up, the rod 10 rises together so that the 1st coil spring 12 is contracted. As a result, the 1st coil spring 12 tries to be elongated and its power is operated to cancel the jump-up power of reversing preventing member 1. Besides, when the reversing preventing member 1 swing backward and the roller 5 is landed on the streamlined member, it is similar as well.
