。[Claims for Utility Model Registration] (1) A base plate fixed on the lower structure, an upper shoe fixed on the upper structure, and a movable shoe disposed between the upper shoe and the base plate to allow displacement of the upper structure. In a movable support consisting of a lower shoe equipped with a member, the base plate is formed with a stepped hole consisting of a large diameter part and a small diameter part whose diameter is reduced by the large diameter part and a step part, and the base plate is embedded and fixed on the lower structure with one end protruding from the lower structure,
and a fixing bolt whose large diameter portion is fitted into the protruding end of an anchor bar having a threaded hole on the protruding end surface, and which is also fitted into the small diameter portion and whose threaded portion is screwed into the threaded hole of the anchor bar. The upper shoe is fixed at both ends of the lower surface in the direction perpendicular to the bridge axis, and the upper shoe is provided with a guide part that hangs down along the bridge axis direction, and the upper shoe is fixed to the upper structure at the guide part to the fixing means. between the upper shoe and the base plate, a lower shoe having a pot-shaped recess on the upper surface is fixed on the base plate with its surface perpendicular to the bridge axis facing the guide portion. A movable support, characterized in that a movable member is housed in the pot-shaped recess of the lower shoe, the movable member slidingly contacting the upper shoe and allowing displacement of the upper structure. (2) The movable support according to claim (1) of the utility model registration claim, characterized in that a sliding member is disposed between the surface of the lower shoe in the direction perpendicular to the bridge axis and the guide portion.
