えるものである。Furthermore, the relative positions of the upper and lower shoes 1 and 8 in the direction perpendicular to the bridge axis are determined by the engagement of the concave groove 4 of the upper shoe and the convex strip 10 of the lower shoe. Even if there is a deviation in this direction, the position of the upper shoe 1 placed on the lower shoe 8 can be adjusted by moving the lower shoe 8 within the recess 18 of the bottom plate.
Even after the adjustment, the lower shoe 8 and the bottom plate 15 can be easily fixed because the fixing block 23 is provided with the oblong fixing hole 25.

分担するものである。In this embodiment, a side block 19 locks the upper and lower shoes 1 and 8 in the vertical direction and engages with a notch 6 of the upper shoe 1 to restrict movement of the upper shoe 1 beyond a certain level in the bridge axis direction. The side block 19 is fixed to the side of the lower shoe with bolts 22, but the side block 19 is fixed to the upper surface 9 of the lower shoe by integrally providing a convex portion that engages with the notch 6 of the upper shoe. In such a case, the convex portion is responsible for regulating the upper shoe 1 beyond a certain level, and the side block 19 is responsible only for locking the upper and lower shoes 1 and 8 in the vertical direction.
さらに、下沓８は下部構造Ｂに固定した底板１５に保持
