A supporting structure for a shaft, in which damage to inner ring bores and a shaft outer periphery is prevented. Inner rings (21, 22) are fitted on the outer periphery side of a shaft (10). An outer ring (23) is disposed on the outer periphery side of the inner rings (21, 22). Rolling bodies (24) are arranged between the outer ring (23) and the inner rings (21, 22). A sleeve (1) is fitted between the shaft (10) and the inner rings (21, 22), and the sleeve (1) has a lower hardness than the shaft (10) and the inner rings (21, 22). |
