Abstract: A bearing structure comprises a shaft member, a bearing, an inner ring, a ring-shaped mount which is made of an elastic material, is fixed to a vehicle body and encloses the inner ring, and a dust cover which is fixed to the bearing member and rotates in unison with the bearing member, the bearing member being supported rotatably on the vehicle body via the bearing. The mount includes, on a front side, a rib facing inward in a radial direction and extending in a circumferential direction so as to seal off a first gap formed between the shaft member and the inner ring. A second gap is formed between an inner radial end of the rib and the shaft member. The dust cover covers the rib and the second gap on the front side of the rib. A cutout is formed in a lower vertical portion of the rib.
