Abstract: A brushless motor includes a rotor, the rotor including magnets and a core member. The magnets are arranged around a rotating shaft and sequentially arrayed with N poles or S poles facing each other in a circumferential direction. The core member includes: an annular portion around the rotating shaft; an outer peripheral core part which supports the magnets on an outer peripheral side of the annular portion; and bridges which extend radially between the annular portion and the outer peripheral core part. Each of the bridges is positioned between the magnets adjacent to each other in the circumferential direction. The bridges include one or more first bridges extending over a first range corresponding to a partial range of the core member along a direction of the rotating shaft.

Abstract: The resistance reduction member includes: an attachment portion attached to a lower surface of a vehicle body; a main body surface extending downward from the attachment portion; and a reinforcement portion extending downward from the side of the lower surface of the vehicle body, on a lateral surface of the main body surface on the vehicle rear side, and configured to prevent toppling of the main body surface.

Abstract: A brushless motor including a toothed part with a tooth main body and a tip part. Protruding slant parts are formed on both sides of the tooth tip part. A tip surface is formed on the inner diameter of the tip part to face a magnet. A groove part is recessed in the center of the tip surface and extends in the axial direction. A depth d of the groove part satisfies 0<d?(Lx?Rt)/3. A width Wg of the groove part satisfies Wt>Wg?Wt/2 (Lx: distance between rotor center and a tooth/slant intersection X; X: intersection between an extension line P of a circumferential side surface of the tooth main body and an extension line Q of a slope of the slant part; Rt: radius of the inner diameter of the tooth tip surface; Wt: width of the tooth main body).

Abstract: A multi-layer paint film satisfies paint film performance, such as water resistance, impact resistance and the like, required of an automobile paint film and which has excellent paint film appearance is obtained. The method comprises coating an aqueous first base paint (A) over an electrodeposited cured paint film to form a first base paint film, and then coating an aqueous second base paint (B) over the first base paint film without carrying out preliminary drying by heating after forming the first base paint film to form a second base paint film, preliminary drying by heating is carried out after forming the second base paint film, coating a single-liquid type clear paint (C) over the second base paint film to form a clear coat paint film. These three paint film layers are heated and cured at the same time.
