<P>PROBLEM TO BE SOLVED: To provide a pull-in device for a sliding door that installs only one unidirectional rotary damper in a pull-in member and can arbitrarily control resistance force applied to the pull-in member by the one unidirectional rotary damper. <P>SOLUTION: A pull-in device for a sliding door includes a device body 3 that is installed on an upper frame 2, and an operating member 5 that is installed on a sliding door 4. The device body 3 is provided with a guide member 6 and a pull-in member 8 that moves in the opening/closing direction of the sliding door 4 by being guided by the guide member 6. The pull-in member 8 is provided with a unidirectional rotary damper 14, and two pinion gears 13a, 13b that are attached to the rotary shaft end of the unidirectional rotary damper 14 and have pitch circle diameters different from each other. Racks 10a, 10b, which are engaged with the pinion gears 13a, 13b, are installed in the guide member 6 so as to be adjacent to each other in the closing direction of the sliding door 4. When the pull-in member 8 moves in the closing direction of the sliding door 4, the different pinion gears 13a, 13b are sequentially engaged with the racks 10a, 10b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
