ともあった。In the conventional tightening device, the extension of the expansion and contraction stroke of the spring for pulling and pulling the pulling tool is limited in structure, so that the pulling force acting on the tightening cord body is strengthened. There was a limit to this. Further, in this tightening device, it is usual to fix the position by hooking the case on the hook fitting of the anti-skid device for the tire, and the pulling force is applied unilaterally only on the pulling tool side. Was becoming. Therefore, due to the slip resistance of the tightening cord with respect to the hook metal fitting, it takes a considerable amount of time for the tensile force to reach the entire length (until the wearing condition of the anti-skid device on the tire is naturally corrected by running vibration etc.). In some cases, it is not possible to apply a uniform tensile force over the entire length of the tightening cord body.

After straddling along the widthwise end, extend and retract the stretchable member that is pulled out through both ends of the tightening cord body at both outlet sides of the device body to the appropriate position at the widthwise end of the anti-skid device. Try to hook it up. As a result, an urging force is applied to the elastic member in the direction of contraction along the axial direction, so that both ends of the tightening cord body are pulled by the elastic member so that the cord passages of the apparatus main body are moved in the forward direction (pulling opening From the direction toward the discharge port), that is, a tensile force that pulls both sides of the tightening cord body around the device body as a center. Therefore, the pulling force acting over the entire length of the tightening cord body becomes uniform, and the pulling force acts quickly. The tightening cord body drawn in the string passage in the normal direction is prevented from moving in the direction opposite to the normal direction by the string locking mechanism, so that the tension force once acting is not loosened.

The structure can be simplified and the mounting work can be facilitated. Also,
In the tightening device for a tire anti-skid device according to the present invention as set forth in claim 4, the hook portion of the operation piece is hooked at an appropriate position on the widthwise end of the anti-skid device wound around the tire to tighten the tightening cord body. After straddling the widthwise end of the anti-skid device, the widthwise ends of the anti-skid device are stretched with the elastic members that are pulled out through both ends of the tightening cord on both outlet sides of the device body. When it is hooked at an appropriate position of the part, the both ends of the tightening cord body are pulled by the urging force in the shrinking direction that acts on the elastic member, and a pulling force that pulls both sides of the tightening cord body around the device main body is created. In addition to acting, a force is drawn to the device body in the direction of the tire diameter center.

り込まれることとなる。Then, the pulling force causes the operating piece to move relatively to the outside of the tire diameter with respect to the main body of the apparatus, and the engaging claw tool is forcibly changed from the unlocked attitude to the locked attitude, and the tightening cord body is moved. Will be prevented. If the tightening cord body is loosened due to the slippage of the anti-skid device being displaced with respect to the tire due to running and the tension force does not act on the tightening cord body, the force acting on the device body in the direction of the tire diameter center also disappears, On the other hand, the tensile force acting on the elastic member acts so that both ends of the tightening cord body are attracted to each other as described above. The claw tool is changed to the unlocked position, both ends of the tightening cord are pulled,
The tightening cord is narrowed in the tire radial center direction until a tensile force is applied.

で、この操作を繰り返せばよい。According to the fifth aspect of the mounting method of the present invention, the anti-skid device is wound around the tire, the device main body and the tightening cord body are hooked and held by the tire, and then the elastic member is bent. While forming the hook portion by the above, the both ends of the tightening cord body are pulled out from the apparatus main body by hooking this hook portion on the hook metal fitting at a predetermined position in the anti-skid device. The hook metal fittings are positioned so that the tensions generated in the elastic members are substantially equal on both sides of the hooking portion. As a result, the tensile force acting on both ends of the tightening cord body is also made uniform. This operation may be repeated until the tension of the tightening cord reaches a predetermined value.
