传动带
摘要：
本发明提供一种能够抑制疲劳强度的降低的传动带。传动带(1)通过被夹入至一对滑轮(P1、P2)的滑轮槽(Pv)中的多个元件(2)被环状的环箍(3)捆束从而被构成，在元件的任意一个面(4f、4g)上形成有凸部(8)，且在另一个面(4g、4f)上形成有凸部所嵌合的凹部(9)，在被架设在一对滑轮之间的传动带的弦部(1a)中的、相互相邻的元件彼此的凸部和凹部相互嵌合的状态下，相互相邻的元件彼此中的一方的元件中的凸部的顶端部(8a)与凸部所嵌合的另一方的元件中的凹部之间的间隙(CU、CL)中的、环箍的半径方向上的内侧的间隙(CL)在半径方向上与半径方向上的外侧的间隙(CU)相比而较大。
摘要（英）：

A driving belt that can limit damages on a hoop and elements. A boss projecting from a front surface of the element is inserted into a hole formed on a rear surface of the fellow adjacent element to form an element array, and the element array is fastened by a hoop. A radially inner clearance between a leading edge of the boss of the element and the hole of the fellow adjacent element in the radial direction is set wider than a radially outer clearance between the leading edge of the boss of the element and the hole of the fellow adjacent element in the radial direction, within a straight region of the driving belt between the pulleys.
