<P>PROBLEM TO BE SOLVED: To provide an in-wheel motor driving device in which a filter can be installed while restricting space. <P>SOLUTION: This in-wheel motor driving device 21 has a motor part A for rotatingly driving motor side rotary members 25 and 35, a speed reduction part B for transmitting rotation of the motor side rotary members 25 and 35 to a wheel side rotary member 28, and a wheel hub 32 fixed and connected to the wheel side rotary member 28. The speed reduction part B has eccentric members 25a and 25b eccentrically joined from the axis O of the motor side rotary members 25 and 35, curved plates 26a and 26b relatively rotatably installing the inner periphery on the outer periphery of the eccentric members 25a and 25b and making a revolving motion around the axis O in response to rotation of the motor side rotary members 25 and 35, an outer pin 27 engaging with an outer peripheral part of the curved plates 26a and 26b, and an inner pin 31 joined to the wheel side rotary member 28. The motor side rotary members 25 and 35 have an axial oil passage 57 for supplying lubricating oil to the speed reduction part B, and a filter member 67 for filtering the lubricating oil. <P>COPYRIGHT: (C)2010,JPO&INPIT |
