The restraining seat 2c has a base 2d that projects the upper end of the mounting board 2 forward by bending, and an engaging wall 2e provided at the tip of the base 2d.
This engagement wall 2e is formed except for the right end of the base 2d when viewed from the front, and cuts two slits 2f in the vertical direction,
The width of the object located at the left end when viewed from the front is increased.

On the other hand, the joint 1a of the cover 1
Is formed by an aggregate of three ribs 1c formed in the front-rear direction on the inner wall of the upper end. As shown in FIG. 2, the rib 1c has an engagement groove 1d cut from the lower end at a portion near the back of the cover 1, and the engagement wall 2e of the restraint seat 2c can be fitted into the engagement groove 1d. It is what it was.

The thickness of the rib 1c in the width direction is shown in FIG.
Is smaller than the incision width of the slit 2f of the restraint seat 2c. As shown in the drawing, the arrangement pitch of the ribs 1c is formed so as to match the position of the open portion at the right end of the engaging wall 2e and the positions of the two rows of slits 2f on the left side. The rib 1c can be freely moved in the front-rear direction with respect to the restraint seat 2c.

In the above configuration, the valve unit 20
The connection of the pipes and the mounting of the cover 1 by the mounting board 2 are performed in the following manner.
