ととなつた。 As shown in FIG. 3, a conventional T-shaped joint for connection consists of a T-shaped joint main body 11 which is generally formed by casting or forging, and each has a communication hole extending through the shaft core, and an outer hole of the communication hole. Individual seat bodies 15, 1 made of a soft metal material whose peripheral end serves as a pressure-receiving seat surface
5′, 15″ are the respective screw hole cylinder walls 12, 1
The respective pressure receiving surfaces are connected to the threaded hole cylindrical wall 1 at the intersection of the stepped small diameter channel 16 provided to communicate the
2, 13, and 14 by pressure-fitting and embedding them coaxially. Therefore, in particular, the casting or molded structure of the T-shaped joint body 11 does not generally require a large number of man-hours, and not only requires a number of subsequent cutting operations, but also the individual seats 15, 15'. , 15" must be press-fitted into the bottoms of the respective small-diameter screw holes cylindrical walls 12, 13, and 14, which necessitates a reduction in productivity and an increase in product weight. I decided to invite him.

A cylindrical hole wall 2 having a diameter of 3" and communicating the inside with each other,
2', 2'' are provided protrudingly, and have communication holes 4, 4' that communicate in a T-shape inside, and the outer circumferential ends of the communication holes 4, 4' are each provided with a tapered conical pressure receiving seat. Face 6,
A seat body 5 made of a soft metal material such as brass, copper, or aluminum and having a diameter of 6', 6" is attached to a pressure-receiving seat surface 6,
6' and 6'' are cast at the same time as the injection molding so that they are located coaxially at the bottom of the cylindrical hole walls 2, 2', and 2'', respectively. Metal screw rings 7, 7', 7'' are fixed by casting to the inner circumferential wall near 3, 3', 3''.
