A movable support 29 is mounted on the base support 27 further, and a long hole 43 is fitted to the guide body 29 for the movable support 29. Thus, the movable support 29 (elbow pad) is freely slidable back and forth and is freely horizontally turnable relative to the base support 27. The guide body 28 is pressed and held by a regulating body 39. A first exclusive elastic body and a second exclusive elastic body 73 are mounted on the guide body 28, a first pin-like body 55 pressed by the first exclusive elastic body is fitted to the first engaging groove of the base support 27, and a second pin-like body 57 pressed by the second exclusive elastic body 73 is fitted to the second engaging groove 58 of the movable support 29. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
