いる。As is apparent from FIG. 2, the lower end portion of the tubular mounting portion 7 is a stepped portion 13 having a small diameter formed at the same time when the housing 1 is molded. Further, the rotor shaft 3 is provided inside the tubular mounting portion 7.
The bearing metal 14 is fitted between the end of the cylindrical metal fitting 7 and the end portion of the stepped portion 13. It has a flange portion 12. Therefore, the step portion 13 and the flange portion 12 allow the O-ring mounting groove having a substantially U-shaped cross section to be provided at the end of the cylindrical mounting portion 7.
15 is formed, and a part of the O-ring 8 is fitted therein.

After performing a simple process such as polishing on the step part 13 as needed,
When the small diameter portion of the bearing metal 14 is inserted into the tubular mounting portion 7 and the flange portion 12 is brought into contact with the end portion of the tubular mounting portion 7, the outer diameter of the flange portion 12 is larger than the outer diameter of the step portion 13. Because it is large, it is a step
An O-ring mounting groove 15 having a substantially U-shaped cross section is formed by 13 and the flange portion 12. Therefore, when a part of the O-ring 8 is fitted into the O-ring mounting groove 15, the O-ring 8 is mounted around the tubular mounting portion 7, and when the tubular mounting portion 7 is fitted to the engine side. A reliable seal can be performed.
