The outer ring along the outer edge of the anti-slip device.
After handing over, rotate the rotating body of the tightening operation unit to
String material insertion hole and each string material insertion passage on the outer periphery of the board of the tightening operation part
Insert the string material that is in a relaxed state by inserting it through the
Take up on a take-up disc that secures both ends of the
Tension gradually and pull the outer ring toward the tire center
So, a strong restoring force (tightening force) is exerted on the outer ring due to contractility.
Pull the outer peripheral edge of the anti-slip device toward the center of the tire
Is it possible to firmly attach the tool to the tire peripheral surface?
It can be easily installed even by elderly people and women.
Wear. ． And when the anti-slip device is no longer needed, when removing it, the shaft
Push the body against the spring and slide it in the axial direction
Release the meshing condition of the gear part of the
By removing the take-up disc,
However, the take-up disc will be
Due to the resilience, the string that is wound up is pulled
The material rotates in the direction in which it is pulled, and the cord is gradually relaxed.
Is the pulling force of the outer ring toward the tire center released?
The anti-skid device can be easily removed from the tire circumference.
Wear.
