- the coil spring 15 as the biasing means applies a biasing force indicated by a solid arrow in the drawing so as to keep the standby position at the sub arm 8 at the standby position.
- a coil spring (not shown) in the damper 19 as an urging means exerts an urging force indicated by a white arrow in the figure so as to keep the main arm 7 in the standby position.
- a biasing force indicated by a solid arrow in the drawing toward the retracted position by the coil spring 15 acts on the subarm 8 on the retracted position side of the intermediate position of the subarm 8.
- the roller 18 contacts only the sub arm 8.
- the main arm 7 is transmitted with an urging force indicated by a white arrow in the drawing from the sub arm 8 toward the retracted position via the receiving portion 6. The urging force acting on the main arm 7 and the sub arm 8 continues until the door 2 is closed.
- the retracting device 61 according to the fourth embodiment includes cases 10 and 11, arms, a spring mechanism 12, and a damper mechanism 13. Since the structure of the spring mechanism 12 and the damper mechanism 13 is substantially the same as that of the first embodiment, the same reference numerals are given and description thereof is omitted.
- the main arm 62 is rotatably supported by the sub arm 63 via the shaft 65.
- a receiving portion 25 (see FIG. 15B) that receives the receiving portion 6 is formed between the main arm 62 and the sub arm 63.
- a torsion spring 64 as a biasing means is bridged between the main arm 62 and the sub arm 63 so that the receiving portion 25 is closed.
- the receiving portion 25 is closed at the standby position. Then, as shown in FIG. 15B, the receiving portion 6 comes into contact with the main arm 62 in the standby position, the receiving portion 25 expands, and the receiving portion 25 expands with the abutting portion 62a of the main arm 62. The main arm 62 and the sub arm 63 rotate toward the intermediate position (the drawing position is shown in FIG. 15B, but the same applies to the intermediate position).
- the coil spring 15 as the biasing means and the coil spring (not shown) in the damper 19 are in the standby position.
- An urging force indicated by a solid arrow in the figure is applied to the sub arm 63 at the position so as to maintain the standby position.
- a torsion spring 64 as an urging means exerts an urging force indicated by a white arrow in the drawing so that the main arm 62 at the standby position maintains the standby position.
- a biasing force indicated by a solid arrow in the drawing toward the retracted position by the coil spring 15 acts on the subarm 63 on the retracted position side of the intermediate position of the subarm 63.
- the retracting device is attached to the frame and the receiving seat is attached to the door, but the receiving seat can be attached to the frame and the retracting device can be attached to the door.
- the receiving portion is closed at the arm standby position, but the receiving portion can be narrowed at the arm standby position.
