排気量型エンジンのバルブ停止機構。A rocker arm with a fork-shaped end is provided so as to be able to swing following the cam, and a cap-shaped blocking arm with two small protrusions facing each other in the diametrical direction is attached to the stem end of the valve. The blocking rotor can be rotated between a valve operating position in which the fork-shaped end of the rocker arm engages with the small protrusion and a valve rest position in which the fork-shaped end disengages from the small protrusion; A valve for a variable displacement engine, which is provided with means for rotating the blocking rotor between the valve operating position and the valve rest position, so that the valve can be selectively activated or deactivated depending on engine operating conditions. In the stop mechanism, a small-diameter shaft is drilled at the stem end of the valve that extends through the top wall of the blocking rotor, and a retaining ring is installed in the circumferential groove formed in the small-diameter shaft to prevent the blocking rotor from falling off. A valve stop mechanism for a variable displacement engine characterized by preventing.
