The injection hole plate is formed at its central portion with a convex portion which is substantially axisymmetric with respect to a valve seat axis and which has a circular-arc shaped cross section, and the welded portion is also substantially axisymmetric with respect to the valve seat axis. Inlet portions of the injection holes are disposed in an injection hole arrangement surface diametrically outside of the convex portion and diametrically inside of a valve seat opening inner wall which is a minimum inside diameter of the valve seat, and the injection hole arrangement surface is coplanar with a surface having the welded portion.

An electromagnetic valve according to the present invention includes: a housing (10) having an inflow hole (11), an inner flow path (12), and a discharge hole (13); a valve seat (15) secured in position inside the housing (10); a shut-off valve (16) adapted to abut one surface of the valve seat (15) to shut off the working fluid flowing into the inner flow path (12) through the inflow hole (11); and a pressure regulating valve (17) provided coaxially with the shut-off valve (16) and adapted to control, through adjustment of the dimensions of a gap between itself and the other surface of the valve seat (15), the amount of working fluid flowing to the exterior of the housing (10) through the discharge hole (13). In the electromagnetic valve, the housing (10) is equipped with a whirling member for causing the working fluid having flowed into the inner flow path (12) through the inflow hole (11) to whirl in one direction.

A first guide member is attached at one end face to an S pole side of the permanent magnet. A second guide member is attached at one end face to an N pole side of the permanent magnet, and has its tip end disposed in opposition to a tip end of the first guide member. A magnetoresistive member is disposed in a space between the tip ends of the first and second guide members, the magnetoresistive member being fixedly attached to a non-rotating member.
