Abstract

A shaft seal having a ring shape adheres to an outer peripheral surface of a rotational shaft and thereby seals sealed fluid. The shaft seal partitions a gap between the rotational shaft and a housing to which the shaft seal is mounted, into a high-pressure side and a low-pressure side. The shaft seal is an injection-molded body having a generally U-shape in a sectional view about an axial direction. The shaft seal has a seal lip part that is configured to extend to the high-pressure side and slide on the rotational shaft, and an outer lip part that is disposed at an outer diametrical side relative to the seal lip part. An inclined angle of the seal lip partrelative to the outer peripheral surface of the rotational shaft is 5-20 degrees.
