PROBLEM TO BE SOLVED: To provide a wheelchair bathtub connection sliding structure that prevents unnecessary slide of a seat and prevents unnecessary release of connection between a wheelchair and a bathtub while the connection is easy, and thereby can improve safety.SOLUTION: A carriage 40 of a wheelchair 30 has a connecting arm where a projection is projected to the side connected with a bathtub 12 of the carriage and the projection is provided swingably while being biased horizontally, and a connection part stored in the bathtub so as to cover the projection of the connecting arm substantially in a reverse bowl shape in a connecting portion with the carriage. The projection of the connecting arm curves from the side face to the top, and the projection swings along the curve and is stored so as to slip in the lower part under the connection part when the projection comes in contact with the side face of the connection part, and thereby the carriage of the wheelchair is connected and fixed to the bathtub.SELECTED DRAWING: Figure 1【課題】連結が容易でありながら、不必要な座部の摺動を防止したり、不必要な車椅子と浴槽との連結解除を防止することで、安全性を向上させることが可能な車椅子浴槽連結摺動構造を提供することにある。【解決手段】車椅子３０の台車４０が、台車の浴槽１２と連結される側に突出部が突出し、水平に付勢された状態で突出部が揺動可能に設けられた連結腕と、浴槽が、台車との連結部分に、略逆椀状で、連結腕の突出部を覆うように収容する連結部を有し、連結腕の突出部が側面から上面にかけて湾曲しており、突出部が連結部の側面に接すると、突出部が湾曲に沿って揺動すると共に連結部の下に潜り込むようにして収容されることにより、車椅子の台車が、浴槽に連結固定されることを特徴とする。【選択図】図１
