The first performance member 61 is provided with a first moving guide roller 85 that is immovably installed in the first performance member 61 and movably engaged with the first fixed guide groove 71 extending in a required length in the fixed base member 51. The first fixed guide roller 72 moves relatively to the first moving guide groove 84, and the first moving guide roller 85 moves relatively to the first fixed guide groove 71. As a result, the first performance member 61 moves while adequately being supported relative to the fixed base member 51. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
