摘要： In order to set a position of a movable member in which a strip-like movable member which is disposed to be movable along a width direction perpendicular to a longitudinal direction of the member is disposed so that one edge of the movable member along the longitudinal direction facing a defined line; and the strip-like movable member is positioned with respect to a fixing member under a condition where the one edge is parallel to the defined line to maintain a uniform protruding amount from the defined line is maintained, the one edge of the movable member is made coincident with the defined line; the movable member is temporily fixed to the fixing member by interposing a position setting jig according to the protruding amount between the movable member and the fixing member; and after cancelling the temporarily fixing step to remove the position setting jig, directly fixing the movable member to the stationary member. Alternatively, a position setting jig according to the protruding amount is made coincident with the define line; and after abutting the one edge of the movable member against the position setting jig, the movable member is fixed to the fixing member. Further, position setting jigs for a movable member suitable for the above methods is provided.

摘要： The method reduces vibrations generated in a contactor due to movement of the moving body by which the contactor contacts with a moving body. When a stroke of vibration of the contactor is halved at an intermediate point of an amplitude thereof, the vibrations are made different from each other in frequency between the reciprocation stroke in the forward side which corresponds to one of the halved stroke portions and the reciprocation stroke in the backward side which corresponds to the other halved stroke portion.
