PROBLEM TO BE SOLVED: To provide a variable valve train for an internal combustion engine in which duty-controls an electromagnetic solenoid for moving a connection pin, thereby, reducing power consumption of the electromagnetic solenoid and prevents generation of a hitting sound.SOLUTION: There is provided a variable valve train for an internal combustion engine, in which an electromagnetic solenoid (60) is excited by a control means (70) to protrude movable core members (61, 62) and, thereby, a connection pin (56) is moved against a biasing force of a spring (54) such that both rocker arms (51, 52) are connected and are rocked integrally, wherein the control means (70) duty-controls the electromagnetic solenoid (60) and drives the movable core members (61, 62). |
