To provide a novel power transmission shaft is simple in structure and moreover makes weight lighter and can perform torque transmission between respective power transmission devices, and to provide a propeller shaft device.SOLUTION: A power transmission shaft comprises a shaft member formed cylindrically, a first collar member which is mounted to one end part of the shaft member and a second collar member which is mounted to the other end part of the shaft member. The first collar member and the second collar member include a first body part and a first press fit part and a second body and a second press fit part. The first press fit part and the second press fit part are coupled by serration after being pressed fit so that opening parts formed on both end parts of the shaft member cover the first press fit part and the second press fit part from outside. The first body part and the second body part are coupled by serration or coupled by spline with a rotational shaft of the power transmission device.SELECTED DRAWING: Figure 2
【課題】簡単な構成で、しかも重量を軽くして夫々の動力伝達装置の間のトルク伝達を行うことができる新規な動力伝達軸、及びプロペラシャフト装置を提供する。【解決手段】筒状に形成されたシャフト部材と、シャフト部材の一方の端部に取り付けられた第1カラー部材と、シャフト部材の他方の端部に取り付けられた第2カラー部材とからなり、第1カラー部材、及び第2カラー部材は、第1本体部と第1圧入部、及び第2本体部と第2圧入部とを有している。第1圧入部、及び第2圧入部は、シャフト部材の両端部に形成された開口部が、第1圧入部、第2圧入部を外側から覆うように圧入されてセレーション結合されている。第1本体部、及び第2本体部は動力伝達装置の回転軸とセレーション結合、或いはスプライン結合されている。【選択図】図2
