Abstract
In a track-guided vehicle wheel truck, a guide frame can be turned relative to a steering axle of a running wheel. A support shaft is adjustably provided on the guide frame. A receiving member is provided projecting toward the vehicle end side. A link lever capable of interlocking the turning of the guide frame and the steering of the running wheel, is provided along the vehicle front and rear direction. A center-side end part of the link lever is rotatably mounted to the receiving member. A vehicle end-side end part of the link lever is rotatably mounted to a connecting rod that enables the steering of the running wheel. A long hole extending in the vehicle front and rear direction, is provided in an intermediate part of the link lever. The long hole and the support shaft are rotatably engaged with each other at a given position.
