In an intake/exhaust valve operation stop mechanism for an internal combustion engine, which bends a second arm at a portion of the connecting pin to absorb movement of the cam and stop the intake/exhaust valve, the side opposite to the connecting pin of the first arm. An adjusting screw having a pivot at the tip is screwed into the base of the adjusting screw, and a first bore that does not interfere with the adjusting screw is bored in the first arm, and a first arm side of the second arm is screwed onto the base of the adjusting screw. a second bore communicating with the first bore, and a second bore communicating with the first bore;
and a piston that can be fitted into the second bore at the same time, and means for moving the piston forward and backward within the first and second bores;
and a second arm that cannot be bent to each other when the piston is fitted into the first and second bores at the same time to open and close the intake and exhaust valves, and that is bent to the other when the piston is released from the second bore. A mechanism for stopping operation of intake and exhaust valves of an internal combustion engine, characterized in that the intake and exhaust valves are stopped by:
