Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of noise and the occurrence of vibration over a long period, facilitate installation and removal of a side groove lid, and facilitate direct placing of a grating. SOLUTION: Joining between a side groove lid 20 and a side groove main body is performed by lower end side surface parts 23a, 23b of the side groove lid 20 and curved parts 14a, 14b of the side groove main body 10. Play of the side groove lid 20 is prevented from being caused by contact between the stepped parts 13a, 13b of the side groove main body 10 and the intermediate stepped parts 22a, 22b of the side groove lid and foreign matter caught therebetween, whereby even if the curved surfaces of the lower end side parts 23a, 23b and the curved surfaces of the curved surface parts 14a, 14b are not brought into face contact with eachother, load concentration is caused in the contact part to remove very small projection and very small distortion so that at least the curved surfaces of the lower end side parts 23a, 23b and the curved surfaces of the curved parts 14a,  14b make line contact close to the face contact, and both transit to face contact due to the change with the passage of time to achieve stable placing state.
