Abstract
A distributor type fuel injection pump which is provided with an eccentric connecting member coupling the timer piston of the injection timing control device to the roller holder. The eccentric connecting member comprises a first portion and a second portion eccentrically combined together. The first portion engages with the roller holder to support a predetermined one of the rollers on the roller holder, which is rotatably fitted thereon, whereas the second portion pivotably engages with the timer piston. Displacement of the timer piston causes corresponding circumferential displacement of the roller holder through the eccentric connecting member to thereby vary the fuel injection timing.
