PURPOSE:To improve the followability by lapping slide plate small pieces each other at adjacent ends of the longitudinal small pieces of shoes by irregular shape longitudinal. CONSTITUTION:Two shoes 4 are integrated by a coupling arm 6, and mounted in a frame of a pantograph to press a slide plate on the upper surfaces of shoes 4 to a trolley wire 5 by a spring tension or the like. Slide plate small pieces 1a, 1b divided from the slide plate into many small pieces are disposed adjacently in one row longitudinally on the upper surfaces of the shoes 4, and the pieces 1a, 1b are arranged to lap each other in an irregular shape at the adjacent ends. The pieces 1a, 1b are secured with bolts on a continuous stainless steel 2 having elasticity.
