A cam piece 19 having two drive cams 19a and 19b is attached to the cam shaft 31 so as to be movable in the axial direction, and the cam moving shaft 4
The fork 43 attached to the cams piece 1
In the variable valve timing mechanism for an internal combustion engine, the cam movement shaft 41 is biased in one direction in the variable valve timing mechanism for an internal combustion engine, in which the two drive cams are selectively switched by moving the cam 9 in the axial direction to operate an on-off valve. A variable valve timing mechanism is provided with a spring 67 for pulling the valve timing mechanism, and is configured to be manually pulled in the other direction by a lever 71 via a wire 699.
