PROBLEM TO BE SOLVED: To provide a current collector for insulated trolley exhibiting excellent durability in which tilting of a yoke post is hard to occur, and the range of relative rotation of the yoke and the post is not regulated. SOLUTION: The current collector for insulated trolley comprises a current collection head 11, a yoke 13 for supporting the current collection head, a yoke post 15 for supporting the yoke rotatably, a base 17 fixed to a movable body, a base post 19 supported on the base rotatably to the right and left, and a parallel arm unit 21 for coupling the base post and the yoke post such that the yoke post can translate for the base post wherein the opposite side faces P of the yoke post 15 are parallel planes coming into plane contact with the inner surface at the distal end of the parallel arms 21A and 21B of the parallel arm unit 21. The yoke 13 is arranged to have a vertical shaft 43 under a current head support 41. The yoke 13 is supported rotatably by the yoke post 15 by inserting the vertical shaft 43 into the shaft hole of the yoke post 15. COPYRIGHT: (C)2008,JPO&INPIT
