<P>PROBLEM TO BE SOLVED: To suppress occurrence of attaching backlash by variation in dimension of a member. <P>SOLUTION: This positioning mechanism has: first and second posts 22 and 23 that are disposed in either part of attaching sections 36 and 37 of a movable member 7 and supporting sections 16 and 17 of a fixing member 11 and project substantially perpendicularly from a surface facing the other part; first and second loose engaging holes 24 and 25 that are disposed in the other part facing the first and second posts and loosely engage with respective facing first and second posts; a sliding member 26 that is disposed in the other part and slides in the direction parallel with the facing surface and substantially perpendicular to the arrangement direction of the first and second loose engaging holes (as in the sliding direction); and an energizing member 27 that is disposed in the other part and energizes the sliding member in the sliding direction. The sliding member has, at the end, two inclined surfaces 26a and 26b branched to the inside and outside with respect to the sliding direction, and abuts on the outer periphery of the second post loosely engaged with the second loose engaging hole on one or both of the inside inclined surface and outside inclined surface. <P>COPYRIGHT: (C)2011,JPO&INPIT |
