An object of the present invention is to realize a structure able to well retain contact performance between an overhead line and a slider 7b, across the entire lengthwise direction of the slider 7b. The slider 7b formed of slider elements 34a and 34b divided in the crosswise direction of a vehicle, is supported on the upper surface of a slider support body 9. A center support member 12 forming the slider support body 9 is elastically deformed downward in a concaved shape across the longitudinal direction, due to a load applied due to contact between the overhead lines and the slider 7b. Also, together with this, both ends of the center support member 12 are supported on a shoe body 3a so as to allow free oscillation via the respective end section support members 13. As a result, even if the overhead lines are positioned on both of the end sections in the lengthwise direction of this slider 7b, the slider 7b is able to track the movement of the overhead lines due to elastic deformation of the center support member 12 and to the rising and falling of the center support member 12, and hence the above object can be achieved.
