    • PROBLEM TO BE SOLVED: To minimize the occurrence of fire and extend the life by using a flame resisting rubber in a plurality of mutually longitudinally separated positions of a coating rubber, and using a rubber having a characteristic different from the flame resisting rubber in the remaining part. SOLUTION: As a flame retardant rubber 3a, a one having the flame resistance grade regulated in JIS K 6324 corresponding to 3 is used. When the wear resistance of a belt is improved, at least a general rubber 3a on the carrying matter placing surface side may be changed to wear resisting rubber. The flame resisting rubber 3a is used for the lateral side end parts of the belt 1, and the general rubber 3c is used for the other part. According to this, even if the side end of the belt makes contact with a frame or the like and ignites, it leads to a fire. The range for using the flame resisting rubber 3a is suitably set to 50-100 mm from the side ends of the belt 1. When it is less than 50 mm, the general rubber 3c adjacent to the flame resisting rubber 3a is partially burnt, and when it exceeds 100 mm, the effect is not improved, but the cost is increased.

    • PROBLEM TO BE SOLVED: To eliminate infiltration of moisture while still supplying ordinary grease by connecting pressure air piping to a grease discharge hole of a bearing box through a pressure reducing valve with a check valve, and installing a relief valve in a branch pipe branching off between the grease discharge hole and the pressure reducing valve. SOLUTION: Pressure air piping 8 is connected to a grease discharge hole 6 of a bearing box 3 through a pressure reducing valve 9 with a check valve, and pressure air is supplied in the bearing box 3 to be put under positive pressure to the periphery. A grease discharge branch pipe is branched off from piping between the pressure reducing valve 9 and the grease discharge hole 6, and a relief valve 7 is installed in this to apply back pressure to piping 8a between the pressure reducing valve 9 and the grease discharge hole 6. Pressure of the pressure air after passing through the pressure reducing valve 9 is denoted by Pa, preset cracking pressure of the relief valve 7 is denoted by Pc, and cracking pressure of the shaft seal part 4 of the bearing box 3 is denoted by Ps, and when these are set to Pa
