出センサ。A case attached to the fuel injection pump and communicating with the inside of the pump, a sensor housing with a double pipe structure fitted into the case, and a sensor housing fitted between the outer pipe and the inner pipe of the sensor housing. The sensor housing includes a detection coil and a mover movable in the tube axis direction within the inner pipe of the sensor housing, and by moving the mover in conjunction with the operation of the fuel adjustment mechanism of the pump, the detection coil is In the fuel injection pump injection amount detection sensor that detects the fuel injection amount of the pump based on the operation of the fuel adjustment mechanism from a change in inductance, the sensor housing has a pump side end of the outer tube connected to the inner tube. The inner pipe has a double pipe structure in which the end opposite to the pump side is closed, and the inner pipe has a double pipe structure that is closed at the end opposite to the pump side, = a seal that maintains liquid tightness between the outer pipe of the sensor housing and the case. An injection amount detection sensor for a fuel injection pump, characterized in that a member is provided.
