摘要： A cam cap is placed on a journal of a camshaft attached to a sprocket to constitute a bearing supporting the journal. The cam cap includes an accommodating groove in which a thrust plate provided on the journal is accommodated, an oil passage having an opening at a position facing a camshaft oil groove of the journal, the oil passage communicating with the accommodating groove, and an oil reservoir provided in a first sidewall of the accommodating groove. The cam cap is placed on the journal such that the accommodating groove is located at a position closer to the sprocket than is the opening of the oil passage. When the thrust plate is accommodated in the accommodating groove, the oil passage and the oil reservoir communicate with each other at a position outward of an outer peripheral edge of the thrust plate in a radial direction of the thrust plate.
