PROBLEM TO BE SOLVED: To increase the strength and durability of a joined part more than the usual thing in which the step length is entirely equalized or the length of a steel cord is arranged in a short order or long oder orderly without changing the processing and structure relating to the cost increase, in the joining part of a belt. SOLUTION: The number of one unit steel cord 2 extended from the terminals 1a of oneside belt 1 is made equal to the number of step n and also the length of respective steel cords 2 is differed mutually by every step length divided in response to the number of step n and the step length (S1, S2,...) are differed to two kinds or more so that the sumΣL of the length L1, L2,... of an anti-load block (slanting line part) which is a section of one step amount mutually adjoining the steel cord extended from the reverse direction mutually is bigger (ΣL>N×D/n) than 1/n of the number of anti-load block N×the interval D between both terminals 1a, 1a' of the belt.
