う。On the other hand, the locking hole (■) at the upper end of the valve b is supported by a locking pin (h) press-fitted into the stepped portion (q) connected to the valve seat (e), and is constructed so as not to hinder the opening and closing of the valve (b). h
Due to the arrangement of the valve body d, the inlet hole l is formed to be offset downward from the axis of the valve body d. The valve body d is inserted into the pipe C, the outer periphery is sized and a bead j is formed using a roll, and the deformed material is press-fitted into an annular groove k formed on the outer peripheral surface of the valve body d. Fix and seal d and pipe C.

ルター１７の開口端を装着する段部である。7 is a pulp having a T-shaped locking portion 8 at the upper end and a horizontal locking groove 9 at one end, and is made of a flapper sheet material. Numeral 10 is a U-shaped locking piece that has a pair of engaging portions 11 that engage with the locking groove 9, and a stopper portion 12 that restricts the press-fitting amount of the engaging portions 11. Reference numeral 13 denotes a hole into which the engaging portion 11 is press-fitted and is provided perpendicularly to the valve seat 6. 14 inserts the valve body 3 into the pipe 2 and creates a bead 16 on the pipe 2 by sizing process.
It is a concave groove that receives the deformable member that is plastically deformed when it is formed, and is formed in an annular shape. Further, the groove 14 is located on the outside of the bore portion 4. Reference numeral 16 denotes a buffer groove for buffering deformation, which is formed between the groove 14 and the valve seat 6 so as to be parallel to the groove 14. Note that 17 is a filter, and 18 is a stepped portion to which the open end of the filter 17 is attached.

ことがない。Effects of the Embodiment In this configuration, the pulp 7 is pre-assembled to the valve body 3 using the locking piece 1o, and the filter 17 is further attached so that one end of the filter 17 is attached as shown by the two-dot chain line in FIG. 2 before the diameter is reduced. After inserting and positioning the pipe 2 into the pipe 2, the pipe 2 is sized to form an inlet bead 15. At this time, due to the concentricity of the bore 4 and the buffer groove 16, the material of the pipe 2 can be deformed uniformly along the entire circumference, and the groove 14 can be sufficiently filled. Deformation around the recess @140 to be formed does not extend to the valve seat 6 due to the buffer groove 16.
