PURPOSE:To prevent the lack of lubricating oil film and the uneven wear of a seal member by providing a mounting hole in a specified range and fixing an antiwear member through the mounting hole to a side housing body with screws. CONSTITUTION:A plate 3 of antiwear member is attached to the surface of a side housing body 2. A range surrounded by an inner envelope A drawn by a side seal and an outer envelope B drawn by an oil seal near the center of the plate 3 is provided with mounting holes 3a. The plate 3 is fixed to the side housing body 2 through these mounting holes 3a by screws to restrain the embossment of the plate 3 and avoid press contact between the plate 3 and the seal portion. Thus, the overheat of a slide surface and the accompanying lack of lubricating oil film can be prevented while the uneven wear of the seal member can be prevented.
