    摘要: To provide a variable valve operating apparatus for an internal combustion engine which can reduce a range where heat treatment is required, thereby favorably suppressing distortion which occurs in a camshaft during heat treatment, to a low level. A changeover mechanism is provided which includes a slide pin which is adapted to move within a predetermined reciprocating range thereby switching between operational states of a variable mechanism, and a guide rail provided in an outer peripheral surface of the camshaft and guides the movement of the slide pin from one end to a remaining end of the reciprocating range. A projection part which is engageable with the guide rail is provided in the slide pin. Restriction means which performs at least one of a restriction of contact between a top surface of the projection part and a bottom surface of the guide rail opposing the projection part, and a restriction of movement of the slide pin beyond a distance from the above-described one end to the above-described remaining end.

    摘要: A variable valve operating apparatus for an internal combustion engine is provided which includes a helical wall part provided in a guide rail for changing valve opening characteristics of a valve and a projection part, and can secure a contact area between the two when the two are engaged, thus successfully reducing the contact pressure generated between the two. The placement of the projection part with respect to the helical wall part is determined such that the central axis line of the projection part and the central axis line of a camshaft perpendicularly intersect with each other in a state in which the projection part is protruded toward the guide rail by an actuator.
