It is formed in a U-shape when viewed from above. Therefore, the plate-shaped portion 63a is reinforced by the rib 63b. Further, as compared with the case where the entire cover-side locking portion 63 is formed as a convex portion having a triangular cross section in a solid shape, the wall thickness of the resin is reduced, and the occurrence of sink marks during molding is suppressed.

(9) The joint-side locking portion 43 is provided with a rib 43b extending radially inward from the circumferential intermediate position of the plate-shaped portion 43a. Therefore, the strength of the joint-side locking portion 43 is improved as compared with the case where only the plate-shaped portion 43a is used. Further, due to the configuration of the plate-shaped portion 43a and the rib 43b, the wall thickness thereof is reduced, and the occurrence of sink marks during molding is suppressed.

The above embodiment can be changed as follows. The above embodiment and the following modified examples can be applied in combination with each other within a technically consistent range.
In the above embodiment, the joint member 40 is formed with a concave joint-side locking portion 43, and the cover member 30 is formed with a convex cover-side locking portion 63, but the joint-side locking portion 43 is convex. The cover-side locking portion 63 may be concave. For example, as shown in FIG. 9A, a convex portion protruding outward in the radial direction is formed at the tip of the joint-side locking portion 43 extending in the axial direction from the tip edge of the joint member 40. Further, the extending portion 61 of the cover main body 60 is made thicker to form a cover-side locking portion 63 as a concave portion that is recessed inward in the radial direction in the thickened portion. Even with such a configuration, the convex portion of the joint side locking portion 43 is locked to the concave portion of the cover side locking portion 63, and the joint member 40 and the cover member 30 can be fixed to the head member 20.

Further, as shown in FIG. 9B, a convex portion protruding inward in the radial direction is formed at the tip of the joint side locking portion 43 extending in the axial direction from the tip edge of the joint member 40, and the cover main body 60 is formed. The extension portion 61 may be thickened to form a cover-side locking portion 63 as a recess into which the joint-side locking portion 43 can be inserted. According to such a configuration, the movement of the joint member 40 in the axial direction is restricted, and the movement of the cover body 60 in the vertical direction is restricted. As a result, the removal of the joint member 40 from the head member 20 is restricted, and the removal of the cover body 60 is also restricted.

In the above embodiment, the joint side locking portion 43 is formed in a shape in which a part of the peripheral wall of the joint member 40 protrudes toward the tip end side in the axial direction, but as shown in FIG. 9C, the joint member A concave joint-side locking portion 43 may be formed in the tubular portion of the 40.

In this case, the position of the joint member 40 may be determined so as not to interfere with the water passage 23 and the water chamber 24 inside the head member 20.

The cover-side locking portion 63 may have a shape divided into a plurality of parts. For example, as shown in FIG. 9D, two cover-side locking portions 63 having the same shape may be arranged side by side.
-The shape of the cover-side locking portion 63 can be changed as appropriate. It does not have to be U-shaped when viewed from above. For example, one or more ribs 63b may be formed not only at both ends of the plate-shaped portion 63a but also at the intermediate portion. Further, the rib 63b may not be provided. Alternatively, it may be a triangular entity in a side view.

-The side surface shape of the cover-side locking portion 63 does not have to be triangular. It may have a quadrangular shape, a semicircular shape, or an indefinite shape. In this case, the shape of the joint-side locking portion 43 that locks with the cover-side locking portion 63 may be appropriately changed according to the shape of the cover-side locking portion 63.
