When assembling the valve portion V of the solenoid valve 1, first, the spool valve 12 is inserted into the valve hole 11 of the valve body 10 through the mounting hole 22, and then the valve spring 13 is inserted. The spool valve 12 is fitted to the short shaft 12a at the outer end. Then, while supporting the outer end of the valve spring 13 with the support projection 23 of the closed end wall 14b, the peripheral wall 14a of the adjusting plug 14 is pressed into the mounting hole 22 until it is inserted into the mounting hole 22, and the set load of the valve spring 13 is reduced by the press-fitting depth. Adjust. In this case, while the hydraulic pressure source 16 is connected to the fourth port 15 4 (input port), a specified current is applied to the linear solenoid unit S, and while the hydraulic pressure of the third port 15 3 (output port) is measured, 14 will promote gradually pressed into the mounting hole 22 of the valve spring 1 when the oil pressure of the third port 15 3 is lowered to a predetermined value
3 is a time when a predetermined set load is applied, and at this time, the press-fitting of the adjusting plug 14 is stopped.

After the adjusting plug 14 is press-fitted, by pressing the peripheral wall 14a of the adjusting plug 14 from the inside with the caulking pin 27 as described above, the concave and convex portions 25 which are closely fitted to both press-fitting fitting surfaces. , 26 are formed to further secure the adjustment plug 14. However, since the adjustment plug 14 is already fixed by press-fitting into the intake hole 22, the adjustment plug 14 is secured even when caulking with the caulking pin 27. Of the valve spring 13 can be avoided, and the set load of the valve spring 13 can be avoided. Further, the indented concave and convex portions 25 and 26 are formed for the first time by caulking.
Unlike the case where the convex portion is formed by caulking on the peripheral wall 14a of the adjusting plug 14 in accordance with the concave portion provided on the inner peripheral surface, the allowable range of the caulking position on the peripheral wall 14a is wide, and the caulking can be performed easily and reliably. Further, since the adjusting plug 14 immersed in the mounting hole 22 can avoid collision with another object, no displacement occurs.

When assembling the valve portion V of the solenoid valve 1, first, the spool valve 12 is inserted into the valve hole 11 of the valve body 10 through the mounting hole 22, and then the valve spring 13 is inserted. The spool valve 12 is fitted to the short shaft 12a at the outer end. Then, while supporting the outer end of the valve spring 13 with the support projection 23 of the closed end wall 14b, the peripheral wall 14a of the adjusting plug 14 is pressed into the mounting hole 22 until it is inserted into the mounting hole 22, and the set load of the valve spring 13 is reduced by the press-fitting depth. Adjust. In this case, while the hydraulic pressure source 16 is connected to the fourth port 15 4 (input port), a specified current is applied to the linear solenoid unit S, and while the hydraulic pressure of the third port 15 3 (output port) is measured, 14 will promote gradually pressed into the mounting hole 22 of the valve spring 1 when the oil pressure of the third port 15 3 is lowered to a predetermined value
3 is a time when a predetermined set load is applied, and at this time, the press-fitting of the adjusting plug 14 is stopped.

After the adjusting plug 14 is press-fitted, by pressing the peripheral wall 14a of the adjusting plug 14 from the inside with the caulking pin 27 as described above, the concave and convex portions 25 which are closely fitted to both press-fitting fitting surfaces. , 26 are formed to further secure the adjustment plug 14. However, since the adjustment plug 14 is already fixed by press-fitting into the intake hole 22, the adjustment plug 14 is secured even when caulking with the caulking pin 27. Of the valve spring 13 can be avoided, and the set load of the valve spring 13 can be avoided. Further, the indented concave and convex portions 25 and 26 are formed for the first time by swaging, and the mounting holes 22 and 22 are formed in advance.
Unlike the case where the convex portion is formed by caulking on the peripheral wall 14a of the adjusting plug 14 in accordance with the concave portion provided on the inner peripheral surface, the allowable range of the caulking position on the peripheral wall 14a is wide, and the caulking can be performed easily and reliably. Furthermore, since the adjusting plug 14 immersed in the mounting hole 22 can avoid collision with another object, no displacement occurs.
