Claim:
An assembling method of a driving belt, the driving belt including a plurality of elements interlinked annularly, each element including a recess that is open to an outer circumferential side of each element, and protruding portions that protrude from opposing open end sides of inner walls of the recess, and a plurality of rings disposed laterally parallel to each other entirely in a length direction thereof without overlapping each other in the recess of each element and held in an inner circumferential side of the protruding portions to prevent detachment of the plurality of rings, the assembling method comprising: aligning the plurality of rings laterally parallel to each other in an entire length thereof; overlapping at least a second portion of the rings of the plurality of rings in a length direction thereof while holding a first portion of the plurality of rings laterally parallel to each other by restricting a relative movement between the plurality of rings; fitting the plurality of rings into the respective recesses of the plurality of elements; restricting the relative movement between the plurality of rings by attaching a detachable fixing member to the first portion of the plurality of rings aligned laterally parallel to each other; and detaching the fixing member from the first portion of the plurality of rings after fitting the plurality of rings into the recess of each element.
