動用Ｖベルト。[Scope of Claim for Utility Model Registration] (1) A wrapped-type V-belt comprising a tensile rubber layer on the upper part of the tension member and a compressed rubber layer on the lower part, and the entire surface thereof is covered with rubberized canvas, A group of notches are formed at a predetermined pitch on the lower surface of the compressed rubber layer, and a concave arch in cross-sectional view of the belt is formed on the lower surface of the compressed rubber layer. A V-belt for power transmission, characterized in that it is formed at a wider angle and further has at least one piece of reinforcing canvas embedded in a lower part of the compressed rubber layer near the notch part. (2) The V-belt for power transmission according to claim 1, wherein the reinforcing canvas is embedded in a position not more than 1/2 of the thickness of the compressed rubber layer. (3) The V-belt for power transmission according to claim 1 or 2, wherein the reinforcing canvas is constructed of a canvas woven from aromatic polyamide fibers. (4) The inner belt portion, which is formed closer to the bottom of the belt and has a wider belt angle than the outer belt portion, is formed in an area of 1/2 or less of the belt thickness.Claim 1 of the Utility Model Registration Claim: V-belt for power transmission as described. (5) The belt angle θ 2 formed at a wide angle on the inner side of the belt formed near the bottom of the belt is:
The belt angle θ 1 of the belt outer portion is in the range of 38°<θ 2 <48°, and the belt angle θ 1 of the belt outer portion is in the range of 36°<θ 1 <46°. V-belt for power transmission. (6) The V-belt for power transmission according to claim 1, wherein the notch is configured such that the gap in the notch shrinks and disappears when the belt is bent to the maximum on the pulley.
