To provide a technology which can inhibit fretting wear at a spigot fitting part between an output member and a wheel member.SOLUTION: A wheel drive device drives a wheel and includes: an output member 42; and a wheel member 44 connected to the output member 42. The output member 42 and the wheel member 44 include a spigot fitting portion 66 in which an outer peripheral spigot surface and an inner peripheral spigot surface are spigot-fitted. An anti-fretting agent 68 is applied to the spigot fitting portion 66, and a seal member 70 that prevents leakage of the anti-fretting agent 68 is disposed between the output member 42 and the wheel member 44.SELECTED DRAWING: Figure 3
【課題】出力部材とホイール部材のインロー嵌合部でのフレッティング摩耗を抑制することのできる技術を提供すること。【解決手段】車輪を駆動する車輪駆動装置であって、出力部材42と、出力部材42に連結されるホイール部材44と、を備え、出力部材42及びホイール部材44は、外周インロー面と内周インロー面とがインロー嵌合するインロー嵌合部66を備え、インロー嵌合部66にはフレッティング防止剤68が塗布され、出力部材42とホイール部材44との間にはフレッティング防止剤68の漏れを阻止するシール部材70が配置される。【選択図】図3
