SOLUTION: The structure comprises: a hand shaft 18 having a hand mount section 18a whose cross section is in an oval form; a seat 31 which has a seat side mount hole 31a in an oval form and a through-hole 31b disposed at a position eccentric from the seat side mount hole, and into which the hand mount section 18a is inserted to pass through; the hand 4 which has a hand side mount hole 4a in a circular form and a through-hole 4b disposed at a position opposite to the through-hole 31b, and into which the hand mount section 18a is inserted to pass through; and a bolt 32 which is brought to pass through the through-hole 31b and the through-hole 4b, and a nut 33 for fixing the hand 4 to the seat. The through-hole 4b is made up as a clearance hole having a gap between itself and the bolt 32. COPYRIGHT: (C)2007,JPO&INPIT
