Kind Code:
B2
Abstract:
To provide a pulling-in device capable of reducing an initial operation load to be applied to an opening/closing member while increasing a real pulling-in load applied to the opening/closing member during a pulling-in operation.SOLUTION: The pulling-in device comprises: a pulling-in member 18 capable of storing a biasing force of a pulling-in direction Db1; a pre-stage transmission path 20 to which the biasing force is input as a first pulling-in load Fa1 from the pilling-in member 18; a post-stage transmission path 24 connected to the pre-stage transmission path 20 through a transmission mechanism 22; the transmission mechanism 22 for converting the first pulling-in load Fa1 input from the pre-stage transmission path 20 into a second pulling-in load Fa2 smaller than the first pulling-in load Fa1 when output to the post-stage transmission path 24; and a path switching mechanism 50 that switches a path for transmitting a pulling-in load from the pre-stage transmission path 20 and the post-stage transmission path 24 to an opening/closing member 12 between a pulling-in operation path for transmitting the first pulling-in load Fa1 from the pre-stage transmission path 20 to the opening/closing member 12 and an opening/closing operation path for transmitting the second pulling-in load Fa2 from the post-stage transmission path 24 to the opening/closing member 12.SELECTED DRAWING: Figure 2
