Abstract
A valve (10) of an embodiment of the present invention has a tapered section (55) on an opening side of a depression (51a) of a body (1). When a projection (4b) of a ball (4) is inserted into the depression (51a), a part of a tip end edge of the projection (4b) is brought into contact with the tapered section (55), and the tapered section (55) guides the projection (4b) so that the entire circumference of the tip end edge of the projection (4b) is located on a bottom side with respect to the tapered section (55).
