<p>An annular member, a sealing device, and a magnetic encoder device are provided. In the annular member, when a circular tube section (71) of the annular member (7) is fitted with interference in either one of an inner member (3) and an outer member (4) that are movable relative to each other, strain in the circular tube section (71) produced by the fitting interference is not transmitted to a flange section (72) to prevent wavy projections and recesses from being produced in the flange section (72). In the sealing device and the magnetic encoder device, even if the sealing device (1) and a magnetic encoder device (50) that have the annular member (7) are fitted with interference in the either one member, strain in the circular tube section (71) produced by the fitting interference is not transmitted to the flange section (72). To achieve the above, the thickness of a bent section (73) of the annular member (7) whose circular tube section (71) is fitted with interference to an axial end surface (31) of a shaft (3) is made less than the thickness of the circular tube section (71) and the flange section (72).</p> |
