PROBLEM TO BE SOLVED: To provide an inexpensive pump for washing machine in which a temperature rise of a coil in a circulation pump is suppressed.SOLUTION: The circulation pump 17 has: a rotation runner 23 having a blade 38 for feeding water; a pump casing 25 including the rotation runner 23: and a pump motor 26 for driving the rotation runner 23. The pump motor 26 has: a revolving shaft 31 having the rotation runner 23; a stator 26a arranged at an outer periphery of the revolving shaft 31; and a rotor 33 arranged outside of the stator 26a. The rotor 33 has a cylindrical part 33a on which a magnet 32 arranged at an outer periphery of the stator 26a is fixed; and a disk part 33b for combining the cylindrical part 33a with the revolving shaft 31. The disk part 33b is provided with a through hole 53c. Thus, it is possible to suppress a temperature rise of a coil with a simple structure inexpensively. |
