。 In a distribution type fuel injection pump in which a solenoid valve for opening and closing the communication passage is interposed in a communication passage communicating between a pump chamber and a plunger pressurizing chamber, the valve member for opening and closing the communication passage of the solenoid valve is made of metal. The valve body has an annular recess at the center of the valve seat surface, and an elastic seal member is attached and fixed to the valve seat surface on the outer periphery of the annular recess. A distribution type fuel injection pump characterized in that a cylindrical guide body is provided on a peripheral edge of the through hole so as to fit into a recess of the valve body when the valve member is seated on the seat surface.
