Abstract
In a discharge valve device, a protuberance penetrates a vertical channel with a raised portion engaging a channel. Thus when an attempt is made to rotate a cylindrical body in the circumferential direction with a raised portion engaging a channel, contact between the protuberance right side surface and the vertical channel restricts rotational movement of the cylindrical body in the circumferential direction.
