PROBLEM TO BE SOLVED: To provide a variable valve gear of an OHC-type internal combustion engine in which a connection pin and a pressing force transmission member are arranged on a crankcase side in a cylinder axial direction as much as possible and the upsizing of a cylinder head and a head cover is avoided.SOLUTION: In a variable valve gear of an OHC-type internal combustion engine, a connection pin (71) is arranged between rocker arm shaft insertion holes (57h and 58h) of rocker arms (57 and 58) and action side ends (57vv and 58vv), pluralities of stud bolt fastening holes (115, 116, 125, and 126) and rocker arm shaft support holes (112h and 122h) are formed on a cylinder head (33), and a sliding hole (102) of a pressing force transmission member is formed in a position that is between the stud bolt fastening hole (125) being nearest the rocker arm shaft support hole (122h) and the rocker arm shaft support hole (122h) and that overlaps with the rocker arm shaft support hole (122h) in a cylinder axial direction. |
