[Claims for Utility Model Registration] (1) A part of a cylinder head that supports a camshaft with a bearing is fixed opposite to a bearing gap that is supplied with oil from inside the camshaft, and is connected to the bearing support part of the camshaft and from this. The camshaft locating plate is also provided with a lubricating structure for a camshaft locating plate which is interposed between the camshaft locating plate and a locking portion provided at appropriate intervals in the axial direction to fix the axial position of the camshaft. A first oil groove communicating with the bearing gap and isolated from the outside is provided on the thrust surface facing the bearing support portion, while a first oil groove communicating with the outside at least partially is provided on the thrust surface facing the locking portion. A camshaft locating plate lubrication structure featuring two oil grooves. (2) The lubrication structure for a camshaft locating plate according to claim 1, wherein the first oil groove and the second oil groove are each provided in pairs, upper and lower. (3) The flow resistance of lubricating oil passing through the passage leading from the bearing gap to the outside via the first oil groove, between the camshaft locating plate and the camshaft, and the second oil groove is greater than the bearing gap and the passage leading to the outside. The camshaft locating plate lubrication structure according to claim 1, wherein the lubrication structure is set to be approximately equal to the flow resistance of the lubricating oil flowing to the opposite side of the shaft locating plate.
