PROBLEM TO BE SOLVED: To attain a configuration capable of keeping a satisfactory contact between an overhead wiring and a contact strip 7b throughout the overall longitudinal direction of the contact strip 7b. SOLUTION: The contact strip 7b composed of contact strip devices 34a, 34b divided in a width direction of a vehicle is supported at an upper surface of a contact strip support body 9. A central support member 12 which composes the contact strip support body 9 is elastically deformed in a recessed condition downward throughout the longitudinal direction based on load applied corresponding to contact between the overhead contact line and the contact strip 7b. Besides, both the edge parts of the central support member 12 are oscillatably supported at a shoe body 3a freely through the respective edge part support members 13, 13. As a result, even when the overhead wiring is positioned at both the edge parts in the longitudinal direction of the contact strip 7b, the contact strip 7b can be made to follow a change in the overhead wiring based on elastic deformation of the central support member 12 and elevation/lowering of the central support member 12, thus solving the above problems.
