AXLE SUPPORT STRUCTURE FOR MOTORCYCLE

摘要

PROBLEM TO BE SOLVED: To provide an axle support structure for a motorcycle which prevents intrusion of water and dust into rolling bearings even when operation torque is kept low and of which performance is not dependent on accuracy of peripheral components.

SOLUTION: The axle support structure for the motorcycle includes: the two-row rolling bearings each including one or two rolling bearings; an axle fitted to inner rings of the two-row rolling bearings and having both end parts coupled to a vehicle body side via forks; and a wheel hub fitted to outer rings of the two-row rolling bearings and rotatably supporting a tire via a wheel. In at least one rolling bearing on the outer side of the two-row rolling bearings, a seal mechanism is built into the rolling bearing.
