Abstract

A pump device includes a rotating body, a pump housing (2) including a suction port (83) and a discharge port (84), and a relief valve (9). In the pump device, a fluid is sucked from the suction port (83) and discharged from the discharge port (84) by rotation of the rotating body. The relief valve (9) includes a valve body (91) and a biasing member. The discharge port (84) includes an one end in a direction in which the discharge port (84) extends. The one end is shallower than a middle portion of the discharge port (84). The pump housing includes a relief flow path through which the fluid flows when the relief valve (9) opens. The relief flow path is provided so as to be open to a groove bottom surface of the one end of the discharge port (84).
