とを特徴とするウエビング巻取装置。 A cylindrical member in which one end of the webbing is locked, the webbing is spirally wound around the outer periphery, and a spiral groove is formed in the inner periphery; A shaft member is formed with a straight groove extending in the axial direction on the outer circumference and is prevented from rotating in the direction of pulling out the webbing under predetermined conditions, and a cylindrical member is movably engaged with both the straight groove and the spiral groove. A blade member that cuts the shaft member along the straight groove by moving while being guided by both the linear groove and the spiral groove due to relative rotation with the shaft member, and a blade member that releases the connection when a relative rotational force exceeding a predetermined value is generated. A webbing take-up device comprising: a connecting means for connecting a cylindrical member and a shaft member.
