To provide a tire chain tightening device that can prevent an engagement portion from being damaged even when a tensile load equal to or greater than a predetermined value is applied to wire.SOLUTION: A tire chain tightening device 10 is configured such that a rotor 24 provided in a casing 12 performs pulling out or winding up of wire 38 and is provided with first lock means 32 that prevents the rotation of the rotor 24 to disturb the wire 38 from being pulled out and second lock means 36 that operates with a change occurred in the wire 38 or the rotor 24 when a tensile load greater than a load usually applied to the wire 38 is applied and then comes into contact with the rotor 24.SELECTED DRAWING: Figure 1

    【課題】ワイヤに対して所定値以上の引っ張り荷重が加えられたとしても、係合部の損傷を防ぐことのできるタイヤチェーンの締付装置を提供する。【解決手段】ケーシング12内に備えた回転体24によりワイヤ38の送出しや巻取りを行うタイヤチェーンの締付装置10であって、回転体24の回転を抑制してワイヤ38が引き出される事を阻害する第1ロック手段32と、ワイヤ38に対して通常付与される引っ張り荷重を超える荷重が負荷された際にワイヤ38、または回転体24に生じる変化に起因して稼働し、回転体24に接触する第2ロック手段36と、を備えたことを特徴とする。【選択図】図1
