A valve structure is disclosed which is mechanically simple and is suited for use in an overhead-valve engine having a hemi-spherical combustion chamber. In the valve structure, inlet valve 3 and exhaust valve 2 are positioned in such a manner that they incline substantially like a 'V' in front view to form an acute angle therebetween. Positioned on a first inclined plane U1 are the longitudinal center lines 2a, 4a and 1a of the inlet valve 2, the associated push rod 4 and the associated rocker arm 1, which connects these, respectively. Positioned on a second inclined plane U2 are the longitudinal center lines 3a, 4a and 1a of the exhaust valve 3, the associated push rod 4 and the associated rocker arm 1, which connects these, respectively.
