る。FIG. 1 shows a configuration diagram in which a sacrificial anode material is connected to a pigtail portion of an in-tank motor in one embodiment of the present invention. In FIG. 1, a brush box 10 is fixed to a brush holder 9 arranged and fixed in a motor frame 5.
A brush spring 11 and the carbon brush 1 are movably housed inside the carbon brush 1, and the carbon brush 1 is pressed against the commutator 6 by the brush spring 11. A flexible conductive wire pigdill 2 is fixed to the carbon brush 1,
The power supplied to the brush box 10 is supplied to the commutator 61 through the carbon brush 1. Sarako, Pigdill 2
A sacrificial anode material 7, which has a greater tendency to ionize than metals such as the brush box 10 and the commutator 6° pigdil 2, is fixed to the sacrificial anode material 7.

合金である。As described above, even when the motor with the above structure is immersed in alcohol fuel, the sacrificial anode material 7 serves as a corrosion-protective electrode, and the brush box 10, commutator 6, etc. have a smaller ionization tendency than the sacrificial anode material 7. Since the anti-corrosion current flows through the metal such as the pigdil 2, the negative side, that is, the metal constituting the motor, is protected from corrosion. This sacrificial anode material 7 is, for example, a zinc alloy or a magnesium alloy.
