PURPOSE: To simplify the construction of a pendulum beam support part supporting a pendulum beam which sustains a vehicle body via rollers on the frame of a trolley and reduce the size of the support part by using the rollers as bearings which can endure the radial or the thrust force.
CONSTITUTION: A pendulum trolley has a roller bearing 23, of which the bottom face is formed archedly along the direction of the width of a vehicle, at the lower face of a pendulum beam 3 which supports the body of the vehicle via a pneumatic spring put at the upper part. This roller bearing 23 is supported movably by rollers 26 put at the side of a trolley frame 8. In such trolley each of the rollers 26 consists of two tapered bearings assembled reverse to each other into a shaft 27 stuck to a bearing holder 25 which is mounted on the trolley frame 8. A lip 24 is placed in a gap between the bearing holder 25 and the roller bearing 23 and covered to protect the tapered bearing 26 from dust.
