Abstract
A support plate is accommodated in the interior of a casing, the support plate having a bearing member that rotatably supports a rotating shaft of a brushless motor, together with supporting a circuit substrate on which a control circuit is provided. The casing is constituted by combining a lower side half body and an upper side half body. A second flow passage through which cooling air (air) is allowed to flow is formed in the lower side half body, and a protrusion is provided therein, which serves as a guide member for guiding the cooling air toward the side of (a first flow passage of) the upper side half body.
