Abstract: A brushless motor includes a motor part and a gear part. The motor part includes: a rotating shaft, having a first gear; a rotor, having a bottom wall and a side wall, the bottom wall being fixed to the rotating shaft; magnets, fixed to the side wall and arranged side by side in a circumferential direction of the rotor; a stator, provided between the rotating shaft and the magnets in a radial direction of the rotor and wound with a coil; and a motor housing, rotatably supporting the rotating shaft, and accommodating the rotor and the stator. The gear part includes: a second gear, meshed with the first gear; an output shaft, having an output part, having a base end side thereof fixed to the second gear, and parallel to the rotating shaft; and a gear housing, rotatably supporting the output shaft, and accommodating the second gear.

Abstract: Hot-dip galvanized steel sheet, wherein said coating layer is characterized by being highly resistant to flaking either in a high-temperature humid atmosphere or in long-term indoor aging. The coating comprises 0.1 to less than 0.2 wt % Al, 0.1-0.5 wt % Sb, the remainder being Zn and unavoidable impurities, the total of the unavoidable impurities other than Fe, namely Pb, Cd and Sn being less than 0.02 wt %, the ratio of Sb/Pb being 10-250, and the Al present in the coating layer being in the form of an Al-Sb eutectic.
