CONTACT TYPE POWER FEEDING APPARATUS
摘要:
There is provided a contact type power feeding apparatus in which, even if a brush Br disposed in a space between the axis body and the cylinder body that are disposed concentric with each other wears out as a result of sliding, contact can be surely secured between the brush and the axis body as well as the cylinder body, thereby efficiently causing electric current to flow between the two. A brush Br has first brush pieces each having an inner wall surface to make surface-contact with an outer peripheral surface of the axis body; and second brush pieces each having an outer wall surface to make a surface-contact with an inner peripheral surface of the cylinder body. The brush is constituted by alternately arranging, in the circumferential direction, the first brush pieces and the second brush pieces in a state of keeping them in surface-contact with each other. The side wall surfaces of the first brush pieces and the second brush pieces are respectively formed into a tapered shape which is inclined relative to the radial direction. Coil springs are disposed between the second brush pieces that are adjacent to each other, in order to give a biasing force in a direction to move the second brush pieces away from each other.
