Claims

[Scope of utility model registration request]

The cam disk is pressed against the cam surface of the cam disk engaged with the drive shaft via a plurality of radially arranged rollers, and is also connected to an injection timing adjustment device that operates according to the rotation of the engine to adjust the injection timing to the corresponding advance position. In a distribution type fuel injection pump including a controlled roller holder, an eccentric pin is formed by integrating a first pin part and a second pin part and centering the axes of these pin parts, and the eccentric pin A predetermined roller among the plurality of rollers is rotatably supported on the roller holder by a first pin portion, and the roller holder is connected to the injection timing adjustment device by a second pin portion. A distribution type fuel injection pump characterized by:
