PURPOSE:To improve the travel performance while to prevent noise by forming short lugs which will never reach to the lateral end of belt body with predetermined interval. CONSTITUTION:Main lugs 31, 31 are extending from the center of central portion A toward the opposite side sections B, B to reach to the lateral ends B1, B2 while main lugs 31, 31 in the right and left rows are shifted each other. In other words, one main lugs 31 are provided along the projection area at one side of a core metal 4 while the other main lug 31 are provided along the projection area at the other side of the core metal 4. The central short lugs 32, 32 will never reach to the lateral ends B1, B2 of the belt body 1. Consequently, wide spaces S, S are formed near to the lateral ends B1, B2 of the short lugs 32, 32, which are shifted longitudinally and arranged along the side in front and rear of the core metal. |
