WIPO Patent Application WO/2021/060442
Kind Code:
A1
Abstract:
A disc rotor 4 has, in an integrated manner: a rotor part 5 including a disc-shaped rotor bottom plate portion 6 attached to an axle 1 and a rotor cylinder portion 7 cylindrically extending from the outer periphery of the disc-shaped rotor bottom plate portion 6 toward one side of the axial direction; and a toroidal plate-shaped disc part 8 disposed on a radially outer side of an end of the rotor cylinder part 7 on the one side of the axial direction. A dust shield 15 has: a plate-shaped outer diameter side shield part 25 located in proximity to and opposite, from the one side of the axial direction, the disc part 8 of the disc rotor 4; and a cylindrical inner diameter side shield part 21 protruding from the outer diameter side shield part 25 toward the other side of the axial direction. The dust shield 15 is fixed to a vehicle body that supports the axle 1. The outer circumferential surface of the inner diameter side shield part 21 is located in proximity to and opposite, from the inside in the radial direction, the inner circumferential surface of the rotor cylinder part 7 of the disc rotor 4.
