PROBLEM TO BE SOLVED: To provide a seal device less prone to generate a clearance in a fitting part even in rise atmospheric temperature in use, to have high heat durability. SOLUTION: This seal device 30 fixes its seal part 31 to an outer ring 2 by a mount part 8, by making it consist of a thermosetting resin which can be injection molded, dimensional contraction and creep deformation due to heat hysteresis are reduced to be different from in the case that the mount part 8 consists of a thermoplastic resin. Accordingly, generation of a clearance between the mount part 8 and the outer ring 2 is made difficult, seal performance between the outer ring 2 and an inner ring 3 can be improved. The thermo-hardening resin has a low resin temperature at molding, different from the thermoplastic resin, when a magnetic sensor 7 and its harness are molded to the mount part 8, a thermal influence given to these electronic parts can be decreased, reliability of the electronic part can be improved. |
