Drive belt (3) comprising several hundred transverse elements (20) provided on and in sliding relationship with an endless carrier (10) having a top section (27) located radially outward from an axially oriented rocking edge (25) with a longitudinal dimension that increases slightly in radially outward direction. On average between the transverse elements (20) of the drive belt (3), the said increase in longitudinal dimension of the said top section (27) in radially outward direction is larger than (Formula (I)) wherein Dr is the longitudinal dimension of the transverse elements (20) at the rocking edge (25) thereof, Csi is the amount of a longitudinal play that is initially incorporated in the drive belt (3) as measured when the belt (3) is placed in a circular posture between the rocking edges (25) of the transverse elements (20) thereof, and wherein L is the belt's circumference length at the rocking edge (25) of the transverse elements (20) thereof.

To efficiently assemble or manufacture a belt by fastening a plurality of elements in a circular manner using a ring. A belt assembling method for assembling a belt 1, by fastening a plurality of plate-like elements 6 in a circular manner, using a ring 9 having a width wider than an opening width of an opening 12 formed in the element 6, comprising: holding the elements 6 in an inner circumferential side of the ring 9 in an orientation to open the opening 12 toward an inner circumferential face of the ring 9; inclining the ring 9 while displacing widthwise by pushing an outer circumferential face of the ring 9 partially toward the opening 12, at a side of one of open ends of the opening 12; and relatively moving the ring 9 and the element 6 close to each other thereby letting the inclined ring 9 through the opening 12 to fit the ring 9 with the element 6.

To efficiently assemble or manufacture a belt by fastening a plurality of elements in a circular manner using a ring. A pair of receiving members 23 and 26 for holding the ring 9 respectively comprises a first receiving face 37 to which the ring 9 is applied, and a second receiving face 28 which is formed outer circumferential side of the first receiving face 37 to hold the element 6 attached to the ring 9 therebetween. A thrust mechanism 30 is adapted to straighten a portion of the ring 9 between the receiving members 23 and 26 by moving at least one of the receiving members 23 and 26 away from the other receiving member thereby applying a tension to the ring 9, and to adjust a distance between the receiving members 23 and 26 thereby equalizing the tension being applied to the ring 9 in both of a case in which the ring 9 is applied to the receiving member 23 and 26 and a case in which the element 6 attached to the ring 9 is applied to the receiving member 23 and 26.

To provide an element for a driving belt, which is easy for a ring to be fitted into a recess of the element, and which is capable of preventing deterioration of durability thereof. An element E as a plate-like member comprises latch portions 8 and 9 formed on an opening end side of each inner side wall 5a and 6a of the recess 7 to hold a ring R in its inner circumferential side. The elements E thus structure are juxtaposed in a circular manner to be fastened by the ring R to form a driving belt V In the element E, a holding face 15 and 16 are formed on an inner circumferential face 8b and 9b of the latch portion 8 and 9 to be opposed to an outer circumferential face 13a and 14a of the ring R and to be contacted with the outer circumferential face of 13a and 14a the ring R to hold the ring R, and a relief area 19 and 20 are formed by depressing a portion of each of the inner side wall 5a and 6a at an inner circumferential side of the holding face 15 and 16.

Drive belt (3) for power transmission between two adjustable pulleys (1, 2) of a continuously variable transmission comprising a number of relatively thin metal transverse elements (32) slideably provided on two endless carriers (31; 31a, 31b) that each comprise a laminated set of mutually nested flat and thin metal rings (30), which transverse elements (32) comprise a top part (33) and a bottom part (35) mutually connected by a pillar part (34) of the transverse element (32), with a laterally open slot (36) being defined on either axial side of the pillar part (34) for respectively receiving one of the endless carriers (31; 31a, 31b), and which transverse elements (32) are provided with longitudinally protruding stud (38) and with a complementary hole (39). The drive belt is provided with urging means for providing at least one of the endless carriers (31; 31a, 31b) with at least a tendency to move in axial direction towards the pillar part (34) of the transverse element (32) during rotation of the belt (3) in the transmission.
