ABSTRACT:
A toggle valve includes a valve stem which moves a valve body towards and away from a valve seat, an operation member separate from the valve stem, valve stem rollers which are supported by the valve stem and which have shafts whose axes extend in a direction perpendicular to the direction of the sliding movement of the valve stem without intersecting the same, a tapered surface provided on the end of the operation member adjacent to the valve stem, and intermediate rollers which are provided between the tapered surface of the operation member and the valve stem rollers to come into contact with the tapered surface and the valve stem rollers. The tapered surface, the intermediate rollers, and the valve stem rollers are arranged such that when the operation member is moved by a unit movement toward the valve stem to move the valve stem through the tapered surface, the intermediate rollers, and the valve stem rollers, the valve stem is moved by a displacement smaller than the unit displacement of the operation member.
