摘要：
本发明提供电动机的转子(10)，其与轴部件包括：轴孔(13)，以中心轴(AX)为中心旋转的轴部件(40)的至少一部分配置其中；以及流路(50)，其在轴部件(40)的周围配置有多个，在与中心轴(AX)平行的方向上贯通。其中，流路(50)的内表面包含：第1面(51)，其朝向轴部件(40)的径向的外侧；第2面(52)，其在径向上配置于第1面(51)的外侧，与第1面(51)隔着间隙地对置；第3面(53)，其连结以中心轴(AX)为中心的旋转方向上的第1面(51)的一端部与第2面(52)的一端部；以及第4面(54)，其连结旋转方向上的第1面(51)的另一端部与第2面(52)的另一端部。设第1面(51)的一端部与第1面(51)的另一端部之间的距离为C、第2面(52)的一端部与第2面(52)的另一端部之间的距离为D时，满足C＜D的条件。(40)连接且以中心轴(AX)为中心旋转。转子(10)
摘要（英）：

This rotor (10) for an electric motor is connected to a shaft member (40) and rotates about a central axis (AX). Said rotor (10) is provided with a shaft hole (13) and a plurality of channels (50). At least part of the shaft member (40), which also rotates about the central axis (AX), is disposed inside the shaft hole (13), and the channels (50), which are laid out around the shaft member (40), each pass through the rotor (10) in a direction parallel to the central axis (AX). The inside surface of each channel (50) comprises a first surface (51) that faces the radial exterior of the shaft member (40), a second surface (52) that is located radially outwards of said first surface (51) and is opposite said first surface (51) across a gap, a third surface (53) that connects one end of the first surface (51) in the direction of the rotation about the central axis (AX) to one end of the second surface (52) in said direction, and a fourth surface (54) that connects the other end of the first surface (51) in said direction of rotation to the other end of the second surface (52) in said direction. The distance (C) between the one end of the first surface (51) and the other end of the first surface (51) and the distance (D) between the one end of the second surface (52) and the other end of the second surface (52) satisfy the relation C < D.
