Also, in terms of design, there is no exposure to the surface of the movable member 62 and the need of a member for hiding in the case of the exposure is eliminated. Further, since the head part 160A is made flat (or sunk) to the surface of the movable member 62, it does not become an obstruction at the time of sticking a seal for decoration to the surface of the movable member 62.  <P>COPYRIGHT: (C)2004,JPO
