Abstract: A disclosed brake lining includes first and second friction member blocks, fastening members, spring members disposed in the fastening members, and a base plate. Each of the first friction member blocks including friction members is elastically fastened to the base plate by two of the fastening members that pass through the spring member and a first back plate. The two of the fastening members are disposed along a circumference of a circle centered around an axle. Each of the second friction member blocks including friction members is elastically fastened to the base plate by three of the fastening members that pass through the spring member and a second back plate. Two of the fastening members lying on opposite ends of each of the second friction member blocks are disposed along a circumference of a circle around the axle.

Abstract: An antislip material ejector comprises an antislip material container 12 which stores antislip material, an air inlet pipe 13 which is arranged in the antislip material container, a compressed air supply pipe 14 which supplies compressed air to the air inlet pipe, a nozzle portion 16 which is arranged in the air inlet pipe, a mixing pipe 17, which is connected with the air inlet pipe, in which the antislip materials are mixed with air and in which a suction hole 18 is formed through which the antislip material passes, a connecting pipe, one end of which communicates with the mixing pipe and the other end of which communicates with a cavity in the antislip material container, and an ejection pipe 20 which is connected with the mixing pipe and which ejects the antislip material together with the compressed air.
