Claims

[Scope of utility model registration request]

A carrier formed by stacking endless metal strips in multiple layers, a carrier groove through which the carrier is inserted, a belt-shaped pitch surface located below the carrier groove in the front direction in the direction of travel, and a rearwardly inclined pitch surface at the bottom of the pitch surface. It consists of a large number of V-blocks that have tapered surfaces and are successively attached to the carrier so that they can move in the circumferential direction of the carrier through the carrier groove, and are wrapped around a pair of ■-shaped belt wheels to receive lubricating oil from the inside. Torque is transmitted between both V-shaped belt vehicles, and when traveling straight, the pitch surface of the ■ block comes into contact with the back surface of the V block in front, and when traveling on a curve, the tapered surface of the ■ block contacts the back of the V block in front. A drive belt for a continuously variable transmission mechanism that comes into contact with the back surface of the block, and the V block has a carrier groove on the top of the front or back surface of the main body section, through which the lubricant supplied to the tapered surface section extends beyond the pitch surface. A drive for a continuously variable transmission characterized by having a concave portion that allows the flow to flow to the side.
