More Information
Summary:Provided are a pump and a fuel injection device, in which fuel discharge failure and fuel pressure failure are prevented by suppressing generation of vapor, thereby enabling vehicles, agricultural machines, generators, and the like, which are provided with internal combustion engines, to operate stably. A pump is provided with: a pump body having a pump chamber defined therein; a plunger reciprocating in response to the rotation of an eccentric cam, thereby feeding fuel sucked in the pump chamber to an injector; and an input portion to which rotational torque from the outside is applied. The input portion is provided with the eccentric earn coupled to a joint member connected to a rotating member; a boss section for rotatably supporting the joint member; and a bush for restricting the axial movement of the joint member.
