发明名称 RAILROAD VEHICULAR JOINT DEVICE
摘要 PROBLEM TO BE SOLVED: To solve the problem wherein ride comfort is damaged by a clearance generated by permanent set in a part, in which an enlarged diameter part of a shock absorbing member and a connector barrel of a front connector are engaged with each other by inserting, when an impact smaller than a set load activating a shock absorber are repeatedly applied. SOLUTION: A diameter enlarging part 18 of a cylindrical part 12a of the connector barrel 12 is inserted into the enlarged diameter part 13a of the shock absorbing member 13 fitted to a lunette 14 for engagement, and the cylindrical part 12a is slidably fitted on a core 14a of the lunette 14. In the state where the connector barrel 12 is pushed into the enlarged diameter part 13a, the connector barrel 12 and the lunette 14 are connected to each other by a constraining means 15, and while the lunette 14 and the connector barrel 12 are fixed by double-split fastening metals 17 and 17, and one of inside opposite surfaces of directed-inward flange parts 17a and 17a of the fastening metals 17 and 17, is engaged with an annular surface part 14e of the lunette 14, and the other is engaged with an annular surface part 12c of the connector barrel 1.
