A novel gene and its encoded protein are described. The apparatus enables a higher throughput per heating channel while achieving equivalent or better devolatilization, as compared to current devolatilization apparatus. The cleaning portion extends in a first direction D1 from the mounting portion to the contact member, wherein a radial direction Dr is defined as extending radially from the central axis a1 towards the outer cleaning surface and normal to the rotational direction \u03b1, and wherein the first direction D1 intersects with the radial direction Dr at an angle \u03b3. The ground contact surface of at least the land portion which is located second when counted from the outer side of a vehicle when the tire is mounted thereon, is arranged so as to have the first circular are and at least a second circular are connected thereto on the vehicle outer side thereof.
