PURPOSE:To mount at O-ring to a piece of parts easily by holding the piece, allowing a support table to support the bottom of an adapter which is inserted in a hole of a jig body, moving down said support table to sink the adapter, and moving back a slider with an O-ring placed upon while tracing the surface of adapter. CONSTITUTION:A piston rod 18 is sunk by a cylinder 17, while a connecting plate 13 in sunk by a contact plat 20 with the aid of an actuator rod 16, and at the same time, an adapter 1 is pushed down by a pressure member 19 to spread an O-ring 7 using a tapered surface 2. A cam 21 sinks with sinking connecting plate 13, and thereby a slider 8 moves back while receiving the spreading O-ring 7. Therefore, the spreading O-ring 7 and the adapter 1 make relative movement, and the O-ring 7 can easy be fitted in a groove Wa in the piece of parts W held by adapter 1 by sinking the groove Wa to the position of O-ring 7 on the slider 8. |
