Abstract:
The present disclosure provides a pump for achieving a reduction of manufacturing man-hours. A pump (1) according to the present disclosure comprises a motor (3) and an impeller (9). The motor (3) has a rotor (10). The rotor (10) has a magnet (7) and a magnet cover (6). The magnet cover (6) covers at least a part of the magnet (7). The magnet cover (6) is formed in a cylindrical shape in the extension direction (D1) of a shaft (11). The magnet cover (6) has an outer peripheral surface (621), an end surface (namely, first end surface (611)), and a plurality of insertion sections (613). The outer peripheral surface (621) follows the extension direction (D1). The end surface extends from one end of the outer peripheral surface (621) in a direction (namely, a perpendicular direction (D2)) crossing the extension direction (D1). The plurality of insertion sections (613) are formed to open in the end surface. The plurality of insertion sections (613) are disposed in an annular shape centered on the shaft (11).
