摘要：The goal of the present invention is to provide an internal combustion enginehead-cover structure capable of suppressing an increase in the wall thickness and size ofa head cover and enhancing the rigidity of the head cover. An internal combustion engine(E) head-cover structure is provided with the following: a covering part (11) which isdisposed on a cylinder head (2) and which covers, from above, a valve gear (3) thatincludes cam shafts (31, 32); an outer peripheral edge part (12) which is provided alongthe outer peripheral edge of the covering part (11) and is fastened to the cylinder head(2); and a plurality of upper bearing parts (13) which are provided integrally with thecovering part (11) and the outer peripheral edge part (12) and rotatably hold the camshafts (31, 32) in cooperation with a plurality of lower bearing parts (23) provided on thecylinder head (2). The internal combustion engine (E) head-cover structure is

characterized by the following: the upper bearing parts (13) are fastened and fixed to thelower bearing parts (23); and the covering part (11) has an expansion part (111) expandingin a substantially hemispherical shape between adjacent upper bearing parts (13).
