In the case of No. 2, since the locking surface 5 is a surface perpendicular to the press-fitting direction of the valve seat 2, when the locking surface 5 is cut by the cutter 37 which is rotationally driven as shown in FIG. Due to the shape of the cutting edge 37a of the cutter 37, it is necessary to cut from the bottom 1 side of the valve housing 12. what if,
As shown in FIG. 7, when attempting to cut from the upper side of the valve housing 12, the cutting edge 37b of the cutter 37 must be a right angle surface like the locking surface 5, but such a cutting edge 37b is a so-called "cutting". It is not feasible because there is no "litter escape". Therefore, the step of cutting the fitting hole 7 for fitting the lid 11 and the step of cutting the press-fitting hole 3 including the locking surface 5 are performed while the same cutter 37 is attached to the cutting machine. It cannot be performed with the valve housing 12 fixed to the same jig. Therefore, there is a problem that the valve body 8 is not properly seated on the valve seat 2 due to the deviation of the axis of the valve seat 2 from the operation axis of the movable core 9, and the valve closed state becomes uncertain.
