Abstract Provided is a motor and an electric power-steering device with reduced dimensions in the axial direction. This motor (1) is provided with the following: a coil support member (60) into which a coil wire (C) is inserted, and that is made of an insulating material; and a heat sink (100) having a through-hole into which the coil support member (60) is inserted. The heat sink (100) is provided with a recess (111) that is located at the upper end of the through-hole, and that exposes the bottom surface as viewed from above in the axial direction. The top surface of the coil support member (60) and the bottom surface of the recess (111) differ from each other in axial direction position. L'invention concerne un moteur et un dispositif de direction assistée électrique ayant des dimensions réduites dans la direction axiale. Ce moteur (1) est pourvu des éléments suivants : un élément de support de bobine (60) dans lequel un fil de bobine (C) est inséré, et qui est constitué d'un matériau isolant ; et un dissipateur thermique (100) ayant un trou traversant dans lequel l'élément de support de bobine (60) est inséré. Le dissipateur thermique (100) est pourvu d'un évidement (111) qui est situé à l'extrémité supérieure du trou traversant, et qui expose la surface inférieure telle qu'elle est vue depuis le dessus dans la direction axiale. La surface supérieure de l'élément de support de bobine (60) et la surface inférieure de l'évidement (111) diffèrent l'une de l'autre dans une position de direction axiale. 軸方向の寸法を低減するモータ及び電動パワーステアリング装置を提供する。本発明のモータ(1)は、コイル線(C)が挿通され、絶縁性の材料で形成されたコイル支持部材(60)と、コイル支持部材(60)が挿通される貫通孔を有するヒートシンク(100)と、を備え、ヒートシンク(100)には、貫通孔の上端部に位置し、軸方向上側から見て底面が露出する凹部(111)が設けられ、コイル支持部材(60)の上面と、凹部(111)の底面との軸方向位置が異なる。
