Abstract
Provided are an ejaculation promotion apparatus and an ejaculation promotion device by which a varied stimulus and tightening force by an appropriate pressure can be obtained, by using an air pressure in a non-closed air cell formed between a core member and a container as a pressure source that provides a stimulus and tightening force to a penis. Included are a core main body () including an insertion inlet () and an insertion empty space (), a plurality of first ribs () projectingly provided on an outer peripheral surface of the core main body at necessary intervals, and extending in an approximately the same direction, and an air resistance member () that allows passage of air along a flow path F while serving as a resistance against the air flowing in the flow path at the time of expansion of an outer diameter of the core main body.
