A tubular elastic linkage device for axle beam for elastically linking a truck frame and an axle beam including: an inner axial member; two outer segments opposed in axis-perpendicular direction peripherally outside the inner axial member for attachment to a housing part on an axle-beam side; and a main rubber elastic body elastically connecting them. A pocket part opens in an outer peripheral face of the main rubber elastic body onto outside via a window penetrating one outer segment. A stopper supported by the inner axial member is disposed in the pocket part to face the housing part distantly via the window. Contact of the stopper with the housing part constitutes a displacement limitation mechanism between the inner axial member and the outer segments. The other outer segment has an aperture having the main rubber elastic body exposed outside via it.

A gasket for an electrical junction box of a railcar is fitted in a groove portion formed on a contact surface of a side wall portion or a contact surface of a cover in the electrical junction box including: a box main body having the side wall portion defining an opening communicating with an outer space; and the cover closing the opening. Further, the gasket for the electrical junction box of the railcar includes: small width portions, a width of each of the small width portions being smaller than a width of the groove portion; and large width portions each having projections projecting toward both respective sides of the small width portion in a width direction and having a larger width than the width of the small width portions. The small width portions and the large width portions are alternately provided.

The present invention provides a rubber stopper that can set a shape suitable for mounting and set a desired stopper characteristic. Specifically, a holding fittingfastened to one member by means of bolting is provided. A rubber sectionthat abuts against the other member is held by the holding fitting. The holding fittinghas a partition wallto divide between a peripheral edge of a bolt holeand a holding sectionthat holds the rubber section. A rubber side abutment surfacein the rubber sectionprotrudes from a top of the partition wall. A bored sectionis formed near the partition wallof the rubber section. The bored sectionincreases durability of the rubber section. A size of the rubber stopperis reduced.
