PURPOSE: A bearing structure is provided to form a stable oil film between the shaft and the bearing and to reduce the load for driving the oil pump to supplement an oil leakage. CONSTITUTION: A bearing structure comprises bearing parts(10,20) which surround a rotating shaft(8) and a sealing part. The sealing part includes an expansion member(40) which expands according to temperature rise and a sealing member(30) which is pushed by the expansion member against the shaft so that oil staying between the shaft and the bearing parts is kept from leaking out. |
