Patent ID: 8636417

Claim:
A wheel support structure for a motorcycle, the wheel support structure comprising: a pair of rolling bearings, each having an outer ring as a rotating ring, an inner ring as a stationary ring, and a plurality of balls that are located in the circumferential direction between the outer ring and inner ring such that the balls can roll freely; a support shaft, both ends thereof being connected to the motorcycle by way of forks; a hub that supports a tire by way of a wheel such that the tire can rotate; a magnetic encoder that is installed in one of the pair of rolling bearings and that has a detected surface; and a magnetic sensor that is fastened to the support shaft or to a non-rotating member that is provided on the support shaft, and that has a detecting surface that faces the detected surface of the magnetic encoder, the magnetic encoder being mounted and fastened to an inner circumferential surface of a cylindrical section, which extends outward in the axial direction from the outer ring, of an encoder installation plate that is attached to an end section in the axial direction of the outer ring of one of the rolling bearings on a first side adjacent to another rolling bearing, or being mounted and fastened to a side surface of a slinger on the first side, which is attached to the end section in the axial direction of the outer ring of the one rolling bearing on the first side such that an end surface on an inner diameter side faces the outer surface of the inner ring to form labyrinth space; wherein the encoder installation plate, the end section in the axial direction of the cylindrical section thereof being pressure fitted into the inner circumferential surface of the outer ring, further comprises: a bent section that is bent toward the inside in the radial direction from the outer end in the axial direction of the cylindrical section.
