<P>PROBLEM TO BE SOLVED: To provide a clearance cover device adaptable to thickness difference of lining plates and to variation of clearance within a predetermined range, and easily attached and detached. <P>SOLUTION: A clearance cover device configured to have: a cover 1 and a clearance plate 4, which are joined perpendicularly with each other; and a rotary hook 13 attached at the lower end of a shaft 5 which is rotatably attached to a through-hole of a height adjusting plate 10 which is provided and elongated in the same direction as that of the clearance plate 4. The clearance plate 4 is inserted into a clearance between lining plates and the rotary hook 13 is rotated so as to become perpendicular to the clearance plate 4 in the lower parts of the lining plates, thereby prohibiting the clearance cover device from being removed. The attachment position of the rotary hook 13 can be changed by positioning of the height adjusting plate 10. When attaching/detaching the clearance cover device, the rotary hook 13 is rotated such that the rotary hook 13 forms the face coplanar to the clearance plate 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
