Claims

[Claims for Utility Model Registration] (1) A pair of roller support pieces provided at both ends of the bottom of the rail tester, a roller shaft supported by the pair of roller support pieces, and a roller shaft at the center of the roller shaft. A roller that is rotatably attached and makes rolling contact with the head of the rail, a pair of copying rollers that are rotatably and movably disposed on both sides of the roller, and each copying roller facing the side edge of the rail's head. A running roller device for a rail tester, comprising an elastic body that is constantly energized and brought into pressure contact with the side edge of the head of the rail. (2) A utility model characterized in that the elastic body consists of a spring for vertical copying that always biases each copying roller toward the rail, and a spring for left and right copying that always biases each copying roller toward the roller. A running roller device for a rail tester according to claim 1. (3) The running of the rail tester according to claim 1, wherein the elastic body is a spring for vertical and horizontal scanning that constantly biases each copying roller toward the side edge of the head of the rail. roller device.
