A U-shaped energizing part 6 of the protecting member 2 is formed into Ω-shape, and both side covering plates 8 always apply the energizing force to the side wall. The energizing part 6 is designed so that the relation between the radius R of the tip of a receiver groove of the sleeve 1 side and the outer diameter γof the head of a cotter fitting, which is attached to a roll, becomes nearly equal to each other due to the thermal expansion in the use condition at maximum temperature. An opening end side of the protecting member 2 is always energized to the sleeve wall side so as to improve the air-tightness between the sleeve and the wall of the receiver groove. The protecting member 2 is provided with a tongue piece for abutting the inner diameter of the sleeve so as to prevent a through-out of the sleeve in the radial direction during the use.
