  "textContent": "There is provided a one-way clutch unit that is simple in structure and compact. An annular recess 67 is provided in an inner periphery of a side of a deep groove ball bearing portion 55 of a first inner ring 7 of a first one-way clutch 1, and an end portion on the side of a deep groove ball bearing portion 65 of a second one-way clutch 2 is disposed in the annular recess 67. Thereby, the dimension in an axial direction of the one-way clutch unit is reduced by a dimension in the axial direction of the second one-way clutch 2 that is disposed in the annular recess 67. The thicknesses on the sides of the deep groove ball bearing portions 55, 65 of the first inner ring 7 and the second outer ring 14 are set larger than those on the sides of the one-way clutch portions 50, 60, whereby deterioration of strength of the one-way clutch unit against radial loads, which is attributable to provision of the annular recess 67 in the inner periphery of the side of the deep groove ball bearing portion 55 of the first inner ring 7, is prevented.",
