を有する。 The tank body 10 is a resin tank body, and a protrusion hole 12 having a flange portion 11 is provided in a part thereof. Positioning bosses 13 are provided on the left and right sides of the outer periphery of the protrusion hole 12, and a pin hole 14 tapered in the center is provided on the outside of the protrusion hole 12. Two to four engaging protrusions 16 having stopper portions 15 are provided.
As shown in FIG. 5, the engagement protrusion 16 is provided on the hole side wall with a width of 1 mm and a depth of 4 mm, for example, so that the tip of the pin hole 14 expands when a taper pin 24, which will be described later, is driven into the pin hole 14. A slit 17 is provided. On the other hand, the pipe 18 is a resin-made inlet pipe or outlet pipe, or a fillerneck pipe used as an injection port, and has a flange 20 having a recess 19 at its end. The pipe 18 is provided with a positioning groove 21 at the end of the recess 19 corresponding to the positioning boss 13, and an engaging protrusion 1 on the flange 20.
A mounting hole 22 is provided corresponding to 6. and,
As shown in FIG. 4, the flange 20 of the pipe 18 having the recess 19 is fitted into the projection hole 12 of the tank body 10 through the O-ring 23, and the engagement projection 16 is fitted into each mounting hole 22. The positioning boss 13 and the positioning groove 21 are aligned to determine the mounting position of the pipe 18, and then the engaging protrusion 1
Drive the taper pin 24 into the pin hole 14 of 6,
Engagement of the engagement protrusion 16 with the mounting hole 22 and engagement protrusion 1
It has a structure in which the pipe 18 is attached to the tank body 10 by driving a taper pin into the pin hole 14 of No. 6.

A flange 20 having a recess 19 of the pipe 18 is fitted to the pipe 18 and the engagement protrusion 16 is inserted into the mounting hole 22.
Since the pipe 18 can be attached by engaging the pipe 18 and driving the taper pin into the pin hole 14, the pipe 18 can be fixed at one time without having to tighten each part individually, as in the case of tightening with a nut, and the pipe 18 can be attached very easily. Furthermore, at this time, if the positioning boss 13 and the positioning groove 21 are matched, the pipe 18 can be installed in an accurate position, and the pipe 18 can be accurately installed in the tank body 10 in a short time. This reduces the number of man-hours and costs. Moreover, since the positioning boss 13 and the positioning groove 21 are aligned, rotation of the pipe 18 is prevented.
From this point of view as well, the installation becomes more secure. In addition, the pipe 18 can be securely attached due to the engagement of the engagement protrusion 16 with the engagement portion 15 with the attachment hole 22 and the engagement effect created by driving the taper pin 24 into the pin hole 14 to expand the hole. , pipe 18
will never come out of the tank body 10.
