PROBLEMTo provide a tire chain tightening device that can prevent damage to an engagement part even when a tensile load equal to or more than a predetermined value is applied to a wire.SOLUTIONA tire chain tightening device (10) feeds and winds a wire (38) by using a rotating body (24) included inside a casing (12). The tire chain tightening device (10) includes a first locking means (32) and a second locking means (36). The first locking means (32) suppresses rotation of the rotating body (24) to inhibit the wire (38) from being pulled out. The second locking means (36) operates due to a change generated in the wire (38) or in the rotating body (24) and is brought into contact with the rotating body (24) when a load that exceeds a tensile load normally applied to the wire (38) is applied.
