The invention provides an in-wheel motor driving device which realizes a fact that the dimension of a terminal box of an in-wheel motor is smaller than that in existing technology. The in-wheel motordriving device (10) is provided with a hub bearing part (11) and a motor part (21). The terminal box (25) of the motor part is provided with a plurality of conductive rods (26u,26v,26w) which extend from the coil side of the motor, and bolts (46) for connecting and fixing a plurality of power line ends (41) with a plurality of conductive ods in the terminal box in a one-to-one manner. The plurality of conductive rods are respectively provided with a through hole or a threaded hole which extends in a preset direction and is used for penetration of the bolt. At least two members in the pluralityof power line ends (41,41,41) are configured in a mutual overlapping manner when viewed in the extending direction of the through hole or the threaded hole of the bolt (46). The plurality of bolts (46) are mounted on the conductive rods in the extending direction of the through hole or the threaded hole of the bolt (46), and are totally configured in a non-overlapping manner when viewed in the extending direction.
本发明涉及一种轮内电动机驱动装置,其使轮内电动机的端子盒的尺寸与以往相比小型化。轮内电动机驱动装置(10)具备轮毂轴承部(11)和电动机部(21)。电动机部的端子盒(25)具有从电动机线圈侧延伸的多个导电棒(26u、26v、26w)、以及在端子盒内部以一对一的方式将多个动力线端部(41)和多个导电棒连接固定的螺栓(46)。在多个导电棒分别设置有沿规定方向延伸并供螺栓穿过的贯通孔或螺纹孔。多个动力线端部(41、41、41)中的至少两个以在螺栓(46)的贯通孔或螺纹孔的延伸方向观察时相互重叠的方式配置。多个螺栓(46)在螺栓(46)的贯通孔或螺纹孔的延伸方向上装卸于导电棒,在该延伸方向上观察时全部以不重叠的方式配置。
