PROBLEM TO BE SOLVED: To secure inflow property of oil into a cylinder head during oiling and reduce the number of parts while suppressing oil from scattering in an oiling part accompanying rotation of a cam shaft. SOLUTION: In the oiling part structure of an engine provided with the oiling part closed by a filler cap on a head cover for covering an upper part of the cylinder head that supports the cam shaft constituting a valve gear, the oiling part is equipped with an opening part positioned above a cam part of the cam shaft, a cylindrical part integrally formed with the head cover and protruding upward from the periphery of the opening part at an upper face of the head cover to/from which the filler cap can be attached/detached, and an oil scattering suppressing wall part integrally formed with the head cover and provided to protrude to the cam shaft side from a portion of the periphery of the opening part at a lower face of the head cover for suppressing intrusion of oil into the cylindrical part that scatters accompanying rotation of the cam shaft.
