PURPOSE: To prevent contact loss by utilizing the attraction force, functioning between a magnet and a ferromagnetic body, for making contact with a conductor.
CONSTITUTION: A magnet 12 is disposed on the contacting part with a trolley wire 2, i.e., a slider 4 or a collector shoe 11, and the attraction force, functioning with respect to the line 1 of electric vehicle including a ferromagnetic body, is utilized for making contact with the trolley wire 2 thus collecting current. Since high contact force can be obtained, contact loss can be prevented. Furthermore, since a part of contacting force functions to pull down the trolley wire 2 through the magnet 12, the trolley wire 12 is not pushed up considerably and damage on the line 1 can be suppressed.
