Patent ID: 8133040

Claim:
A fuel pump comprising: a case member defining a fuel passage therein; a pump section defining an inlet port, the pump section connected to the case member such that the inlet port is in communication with the fuel passage of the case member; a motor section housed in the case member, the motor section configured to drive the pump section; a discharge-side cover defining a discharge port, the discharge-side cover connected to the case member such that the discharge port is in communication with the fuel passage; a positive electrode terminal and a negative electrode terminal each extending from an inside of the discharge-side cover to an outside of the discharge-side cover for conducting electricity to the motor section; a terminal support member being insulative and connected to the discharge-side cover and disposed inside of the discharge-side cover, the terminal support member supporting the positive electrode terminal and the negative electrode terminal; a positive electrode-side insulative portion covering a base portion of the positive electrode terminal, the positive electrode-side insulative portion projecting from the terminal support member; and a negative electrode-side insulative portion covering a base portion of the negative electrode terminal, the negative electrode-side insulative portion projecting from the terminal support member, wherein the discharge-side cover has a first fitting hole and a second fitting hole, the positive electrode-side insulative portion through which the positive electrode terminal passes is fitted in the first fitting hole, the negative electrode-side insulative portion through which the negative electrode terminal passes is fitted in the second fitting hole, the discharge-side cover further has a first guide portion and a second guide portion on an inner surface thereof, the inner surface defining the inside of the discharge-side cover where the terminal support member is disposed, the terminal support member has a first engagement projection and a second engagement projection on opposite side walls thereof, and the first engagement projection and the second engagement projection are configured to be guided by the first guide portion and the second guide portion while restricting the discharge-side cover from rotating with respect to the terminal support member.
