て可撓性無端部材I3の全周に亘って繰返す。Since the embodiment shown in FIGS. 3 to 7 is constructed as described above, the flexible endless member 13 made of endless thin steel plates stacked in multiple directions has a V-shape extending from the inside to the outside. The metal member 7 is moved to fit the notch 11 of the square-shaped metal member 7 into the flexible endless member 13, and the needle roller 2 is engaged with the arc-shaped groove 10 of the square-shaped metal member 7. This process is then repeated over the entire circumference of the flexible endless member I3.
次にこの可撓性無端部材13を円形にした状態で。Next, this flexible endless member 13 is made into a circular shape.

さらπ相隣接するV形金属部材7は1円弧状溝10でニ
ードルローラ12i介して接触されるため。Furthermore, the V-shaped metal members 7 adjacent to each other in the π phase are brought into contact with each other through the needle roller 12i at the one-circular groove 10.
Vベルト6の曲げ変形は可撓性無端部材13の曲げを伴
なうのみで、V形金属部材7はニードルローラ12にて
軽快に揺動でき、動力伝達効率が高い。The bending deformation of the V-belt 6 is only accompanied by the bending of the flexible endless member 13, and the V-shaped metal member 7 can be easily swung by the needle roller 12, resulting in high power transmission efficiency.
さらにまた円孤状溝】0の曲率半径r1の方がニードル
ローラ12の半径r2よりも太きいため、■形金属部材
7とニードルローラ12とは転がり接触し。Furthermore, since the radius of curvature r1 of the arc-shaped groove [0] is larger than the radius r2 of the needle roller 12, the ■-shaped metal member 7 and the needle roller 12 come into rolling contact.
その結果、■形金属部材7とニードルローラ12との摩
耗および摩擦損失が少ない。As a result, wear and friction loss between the ■-shaped metal member 7 and the needle roller 12 are reduced.
