ABSTRACT:
A current collecting apparatus for a transport vehicle such as a linear motor car comprises a mounting member for mounting said apparatus for a truck body of a transport vehicle through an insulator. A supporting member is provided on the mounting member such that the supporting member can be moved in a transverse direction of the transport vehicle by a couple of mount arms rotatably supported to the mounting member. Collecting shoes are supported at the lower end of each of the support arms, respectively, for receiving electric power supplied by a trolley rail. Each of the support arms comprises a couple of joint arms forming a parallelogram linkage for maintaining good contact between the trolley rail and the collector shoes. When the transport vehicle travels along curved tracks, the support arms incline in the transverse direction of the transport vehicle against an elastic force of a contracting spring so as to keep contact between the collecting shoes and the trolley rail.
