Abstract
In a truck for railroad car capable of absorbing and reducing deformation due to torsional force acting on an end beam, end portions of right and left side frames 2a and 2b of a truck frame 2 are connected by an end beam 3. An antenna support member 4 is supported by the end beam 3. The end beam 3 includes antenna brackets 3a and 3b, as right and left support brackets, connected and fixed to outer end portions of the right and left side frames 2a and 2b by fastening tools 5, and a center bar 3c connected to inner end portions of the right and left antenna brackets 3a and 3b through rubber bushes 6 and 7 and having an antenna support member 4. The rubber bushes 6 and 7 are positioned at both sides of the antenna support member 4 of the end beam 3, include elastic rubber members 6a and 7a, and absorb the torsional force acting on the end beam 3 by elastic deformation of the elastic rubber members 6a and 7a.
