In the vicinity of the top of the triangle head between the line parallel to the slit portion and at least one of the front surface and the rear surface in the belt running direction, the thickness near the top of the triangle head gradually decreases toward the top of the triangle head. In the case where the pressing-side linear portion of the assembling-type V-belt is curved inward due to such an inclined surface or a curved surface, adjacent flat plate elements in the pressing-side linear portion have a corresponding relative angle. However, these flat plate elements do not locally contact (per point) at the apex of the triangular head, and these flat plate elements appear along the above-mentioned line which is also the start line of the inclined surface or the curved surface. Contact each other in an area of a certain width. For this reason, the flat plate elements adjacent to each other on the press-side linear portion in the curved inner side of the assembled V-belt do not rotate relative to each other so as to be misaligned with each other in the belt traveling direction. It is bitten in the V groove of the output pulley in an aligned state,
To solve the above-mentioned problems relating to noise and durability which have conventionally occurred due to misalignment of the flat plate element in the belt running direction since the output pulley does not collide with the opposed conical surface forming the pulley V groove. Can be.

問題を解消することができる。In a fourth aspect of the present invention, the vicinity of the top of the triangular head in a region having a predetermined width including the vertex of the triangular head and a predetermined distance from the vertex in the direction of the V-shaped main body portion is defined as a front surface and a rear surface in a belt running direction. In at least one of the above, the plate thickness near the top of the triangular head is made thinner than the remaining plate thickness of the triangular head by recessing the triangular head, so that the pressing-side linear portion of the assemblable V-belt is curved inward. Therefore, even when adjacent flat plate elements in the pressing-side linear portion have a corresponding relative angle, these flat plate elements are not locally contacted (per point) at the vertex of the triangular head. These flat plate elements are in contact with each other in regions of a certain width appearing on both sides in the width direction of the pulley V-groove with the vicinity of the top of the depressed triangular head interposed therebetween. For this reason, the flat plate elements adjacent to each other on the press-side linear portion in the curved inner side of the assembled V-belt do not rotate relative to each other so as to be misaligned with each other in the belt traveling direction. Conventionally caused by misalignment of the plate element in the belt running direction, since it is bitten in the V-groove of the output pulley in an aligned state and does not collide with the opposed conical surface forming the V-groove of the output pulley. The above-mentioned problems relating to noise and durability can be solved.

消することができる。In the fifth aspect of the present invention, since the apex of the triangular head is removed to form the top of the triangular head on a flat surface parallel to the slit, the pressing-side linear portion of the assembling V-belt is curved inward. In the state, when the adjacent flat plate elements in the pressing-side linear portion have the corresponding relative angles, these flat plate elements are likely to locally contact with each other at the apex of the triangular head. However, since the apex of the triangular head does not exist, the local contact (per point) does not occur,
These flat elements contact each other in a region of a certain width appearing along the flat top surface of the triangular head. For this reason, the flat plate elements adjacent to each other on the press-side linear portion in the curved inner side of the assembled V-belt do not rotate relative to each other so as to be misaligned with each other in the belt traveling direction. The pulley V of the output pulley is bitten into the V groove of the output pulley in an aligned state.
Since there is no collision with the opposing conical surface forming the groove, the above-mentioned problems relating to noise and durability conventionally caused due to the misalignment of the flat plate elements in the belt running direction can be solved.
