[Problem that the idea aims to solve]

However, when heating and keeping tires warm using the conventional tire warmer described above, The outer circumferential surface of a tire is curved in the width direction, whereas a tire warmer is flat. It is a band-shaped material that can be made to follow the curved surface of the tire using only its own flexibility. are doing. For this reason, there was a drawback that adhesion to tires was poor. tire warmer If the adhesion between the , the heating efficiency becomes low.

[0005] Therefore, this idea improves the adhesion of the above band-shaped tire warmer. The first challenge is to improve heating efficiency.

[0006] On the other hand, in car races, when entering the lane, the tire warmer is turned on. Since the source code gets in the way, we have to remove it.

[0007] However, there are ceremonies and other events that take place between entering the lane and starting the race. Because of this, tires that have been heated may cool down during that time.

[0008] Therefore, this idea was developed to allow the tires to cool down between the time they enter the lane and the time they start. The second challenge is to prevent this.

[0009]

[Means to solve the problem]

In order to achieve the first and second problems above, this invention covers the outer circumferential surface of the tire. Both side walls covering both sides of the tire are provided on both sides of the peripheral wall of the required width to form a case shape. This structure constitutes a tire heat insulation cover.

0010 As a further embodiment of the above configuration, a circumference that covers half of the outer circumferential surface of the tire is used. On both sides of the wall, both sides cover both sides of each half when the tire is divided into two in the diametrical direction. A pair of cover halves may be combined.

[0011] Furthermore, on one side of the peripheral wall that covers one side of the outer circumferential surface of the tire, a side that covers one side of the tire is attached. A pair of cover halves formed in a dish shape with a wall may be combined.

0012 Furthermore, a self-heating element may be attached to the inner surface of the peripheral wall.

[0013]

[Effect]
