Expansion joint apparatus which can be installed at junctions between upper structures of a road and a bridge. In a state of applying the apparatus to a bridge, each wheel in a same shaft of a vehicle passes the apparatus at different time spots, that is, when any one wheel passes one of the support members, the other wheel passes the other support member. Thus, a load applied to the bridge is distributed. The apparatus is made of material having high stiffness so that it lasts a long time. By changing the number of the intermediate support members, an expansion range of the apparatus can be controlled.
