PURPOSE:To facilitate disassembly and inspection by tightening a frame in demountable manner by a bolt onto a supporting seat through a distant piece having a specific size, thus facilitating taking-out a bearing shoe in the horizontal direction. CONSTITUTION:A frame 10a is tightened in demountable manner onto a supporting seat 9 by a bolt 15 through a distant piece 14. The thickness of the distant piece 14 is set so that the distance H1 between the undersurface of the frame 10a and the upper surface of the supporting seat 9 forms a relation H1>H2 with respect to the height H2 of the part where a support 14 engages with the frame 10a for restricting the movement in the horizontal direction of the bearing shoe 3. When the distant piece 14 is demounted, and the frame 10a is lowered onto the supporting seat 9, the upper surface of the frame 10a is positioned lower than the undersurface of the support 4. Therefore, the bearing shoe 3 can be taken-out with the support 4 integrally formed in the horizontal direction of arrow. With such constitution, the quantity of parts can be reduced markedly, and the time necessary for demounting in disassembly work can be reduced, and the working process can be shortened. |
