A small external wall 23 is provided outside an external wall 22 of a first case half body 2 in two case bodies, and a U-shaped groove 24 into which a tip of a second case half body wall 31 is inserted, is formed by an external wall 22, a small external wall 23, and a part close to an outer peripheral end of a plane 21. Further, a slant 23b is formed on a bottom face side of an internal wall 23a of the small external wall 23. When a tip of the wall 31 is inserted into the U-shaped groove 24 by the slant 23b, the tip of the wall 31 is pushed onto an internal space side of a pump case. Thus, an abutting part of a tip of the wall 31 onto the slant 23b is welded as a main welded part. Therefore, though a weld flash is generated in the main welded part, the weld flash is confined into a space S in the U-shaped groove 24.
