A thrust bearing structure for a camshaft using a bearing member forming a bearing hole for insertion of the camshaft, in which the camshaft is formed with an annular flange facing at least one side of the bearing hole, and the bearing member is provided with an annular flange facing at least one side of the bearing hole. A sliding guide surface of the flange is formed to allow the flange to move like a piston, a pair of hydraulic chambers communicating with each other are formed between the flange and the bearing member, and the camshaft and the bearing member are connected to each other. An oil passage is formed in at least one of the hydraulic chambers to guide lubricating oil from an oil supply source to one side of the hydraulic chamber, and the axial displacement of the camshaft is absorbed by the oil in the hydraulic chamber escaping in accordance with the displacement. A camshaft thrust bearing structure characterized by the following features:
