<P>PROBLEM TO BE SOLVED: To provide a retracting device which can easily recover an automatic retracting function by moving a moving body in a direction of one moving end position or in a direction of the other moving end position even in the case that the automatic retracting function is lost, whose structure and adjustment are simple. <P>SOLUTION: The retracting device comprises a driving member 11 attached to a moving body side or a fixed body side, a sliding member 12, a guiding member 13, and a coil spring 14. The guiding member 13 is provided with a guiding part and a guiding groove 13a having a large diameter part 13c on the end part of the guiding part. By the movement in the direction of the moving end position of the moving body, the sliding pin 12f of the sliding member 12 is slid along the guiding groove 13a and turned in a drawing direction at the large diameter part 13c, a dimension in a direction orthogonal to the guiding groove 13a is changed and locked to the large diameter part 13c. Also, in the retracting device, the engagement of the sliding member 12 and the driving member 11 is released, the driving member 11 and the sliding member 12 are engaged at an automatic retract position by the movement in the direction of one moving end position of the moving body and also the lock of the sliding member 12 is released. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
