  "textContent": "A fuel injection pump pressurizes and injects fuel. A cam rotates about a rotational axis of the cam. A housing includes a cam chamber that houses the cam and a sliding chamber communicated to the cam chamber. A roller rotates while being in contact with a surface of the cam. A shoe reciprocates in the sliding chamber by rotation of the cam and is in contact with and slides on a surface of the roller. A plunger reciprocates with the shoe. A cylinder houses the plunger and includes a pump chamber to pressurize and feed the fuel by reciprocation of the plunger. A deformed section is a groove or a protrusion which extends in a direction of a rotational axis of the cam, on a part of a surface of the cam, and has a shape different from a cam profile of the cam.",
