The invention valve by the rotation of the relates to a valve opening and closing device, the handle to by the operation to rotate the worm 20, the formation of the worm 20, worm wheel 31, which is gear coupled to the outer circumferential surface the wheel body (30) in the configuration for rotating the worm wheel 31 are such that more than 180 ° to ensure a constant width is extruded from the outer peripheral surface of the wheel body 30, the worm wheel 31 is formed integrally with the wheel body (30); Indicator, combined to the upper end of the wheel body 30 so as to protrude to the upper portion of the cover plate (40) covering the upper end of the housing 10 to rotate with the wheel body 30, plate 50; Is formed to protrude a predetermined height in the radial direction from the upper surface of the indicator plate 50, the stopper projection 60, once extruded to the outer diameter of the indicator plate 50, a length to outside to form a barrier portion (61); By spaced apart a predetermined distance from the upper surface of the cover plate (40) being fastened to the bolt end connections (71) which is provided integrally, an obstacle part of the stopper protrusions 60, 61 are an obstacle to ensure that the ends are located in the radius of rotation for rotating portion 61 has a feature to occur in a configuration in which a stopper bolt 70 for limiting the angle of rotation of the wheel body 30 by the contact with.
