An electric hub device has a hub body (26) capable of rotating relative to hub shafts (24, 25) and also has a motor (27) for rotating the hub body (26). The motor (27) has a rotating body (32) provided with a rotating shaft (37) and also has a housing (34) for housing the rotating body (32). The rotating shaft (37) and the hub body (26) are interlocked with each other through a speed reduction mechanism (48). The speed reduction mechanism (48) has a sun gear (49) which is formed on the rotating shaft (37), an annular gear (50) which is provided within the hub body (26), and rotatable planetary gears (51) which mesh with both the sun gear (49) and the annular gear (50). A recess (45) which is recessed inward in the axial direction (A) of the hub shafts (24, 25) is formed in the housing (34), and the sun gear (49), the annular gear (50), and the planetary gears (51) are received in the recess (45). |
