ABSTRACT:
A fuel injection pump includes a camshaft, an eccentric cam, a cam ring, a housing and plungers. The camshaft is rotated by an engine. The cam is provided separately from the camshaft and is formed with a connecting portion connected with the main shaft. The cam rotates with the camshaft. The cam ring revolves around the camshaft so that the cam ring rotates with respect to the cam along an outer periphery of the cam. The housing rotatably houses the cam and the cam ring and is formed with fuel pressurizing chambers. The plungers reciprocate in accordance with the revolution of the cam ring to pressurize and to pressure-feed fuel drawn into the fuel pressurizing chambers. Strength of the connecting portion is set to a value lower than damage strength of the housing.
