A connection end portion of a inner member (41) is provided with engagement projections (41P, 41P) and a connection end portion of a stay (4B) is formed with reception grooves (Bd, Bd) that are capable of axially receiving the engagement projections. When operation cable (40) is axially inserted into a cylindrical support, the engagement projections (41P, 41P) are axially received in insertion grooves (Sd, Sd) and are retained in terminal end positions thereof that are bent in a circumferential direction. When the stay (4B) is axially inserted into the cylindrical support (2S) in this condition, the engagement projections (41P, 41P) are axially received in the reception grooves (Bd, Bd) and move to terminal end positions thereof that are bent in an opposite circumferential direction. As a result, the operation cable (40) is positioned in an axial connection condition in which the operation cable (40) is suspended in the stay (4B).
