Claims

[Scope of utility model registration request]

A housing is constructed by closing the rear end of a cylindrical housing body with a valve housing portion having a valve port at its tip with a lid member. A ring-shaped sealing member is inserted between the inner surface of the mounting hole at the leading end and the rear end to form an annular fuel passage between the valve housing and the inner surface of the mounting hole, and a ring-shaped seal member is inserted into the valve housing to open and close the valve opening. The housing main body houses a drive unit for driving the valve body, and the side wall of the housing is provided with a communication hole for communicating the fuel passage to the valve port. In the injection valve, the rear end opening edge of the housing body is
The fuel injection valve is fixed by caulking to a fitting protrusion provided on the lid member and fitted into the rear end opening edge, and the seal member on the rear end side is disposed on the outer periphery of the lid member. .
