とする巻取り装置。[Scope of Claim for Utility Model Registration] (1) The rope is wound around the drum against the tension of the rope by the forward rotation of the drum, and the tension of the rope is caused by the release of the lock of the pawl that engages with the ratchet wheel that rotates together with the drum. In a winding device in which the rope is unwound by rotating the drum in the opposite direction, the pawl is rotatably attached to a support shaft adjacent to the outer periphery of the ratchet wheel, and the pawl is rotated from the ratchet wheel in the unlocking direction. A winding device characterized in that a stop positioning means is provided, and a second gear that rotates freely relative to the pawl and is in pressure contact with a side surface of the pawl is meshed with a first gear that rotates together with the pawl. (2) The rope is wound onto the drum by the forward rotation of the drum against the tension of the rope, and the drum is rotated in the reverse direction by the tension of the rope as the pawl that engages with the ratchet wheel that rotates with the drum is released. In a winding device for unwinding a rope, a swinging body whose tip faces the outer periphery of a ratchet wheel is rotatably supported midway through a pin, and a pawl is supported at the tip of the swinging body, and a claw is supported at the tip of the swinging body. The ratchet wheel is given return rotation in the direction in which the pawls engage, and furthermore, a portion of the outer peripheral surface is brought into contact with the edge of the end portion of the rocking body in the return rotation direction to release the engagement between the ratchet wheel and the pawls. Along with the posture, a push button whose axis is parallel to the axis of the drum is slidably provided, and a return force is applied to the push button to push it back. A tilting body has a tapered portion that is in an engaging position, and the opposite end of the claw of the tilting body is rotatable, and the tip side is located on the edge connecting the rope guide path and the rope winding groove of the drum. At the same time, the tip of the tilting body is provided with the ability to return to rotation in the direction in which the tip of the tilting body separates from the claw side of the rocking body, and a recess provided on the outer circumferential surface of the tip of the push button is provided at the end of the tilting body. A protrusion that fits and engages with the stepped part is provided, and a pulley is further provided at the tip of the tilting body that engages with the rope and rotates the tilting body so that the protrusion is removed from the stepped part by the tension of the rope. Characteristic winding device.
