A valve open and close apparatus includes a resin housing, a resin valve, and a shaft. The resin housing has a fluid passage inside the housing. The resin valve has a through hole inside the valve and opens and closes the fluid passage. The shaft is press fitted inside the through hole such that the shaft is assembled to the valve. The valve includes a first shaft bearing portions, a second shaft bearing portions, and a press-fit portion. The first shaft bearing portion forms a first slide portion between the housing and the first shaft bearing portion. The second shaft bearing portion forms a second slide portion between the housing and the second shaft bearing portion. The press-fit portion is located at a position other than a radially inward portion of each of the first and second shaft bearing portions. The shaft is press fitted into the press-fit portion.
