。By the way, the above-mentioned latter invention, that is, JP-A-59-. 1
The invention disclosed in Publication No. 7043 is the former invention,
That is, when the steel band in the invention described in JP-A-54-52253 is bent, a tensile force is applied to the outside of the band.
In order to eliminate the drawback of fatigue caused by compressive force acting on the inside, a link chain is used instead of a steel band, but the link chain and the V-block in which the link chain is inserted are relative to each other. The former steel band is also similar in this respect.
したがって、両者は鋼製バンド及びリンクチェーンが■
ブロックと相対的な滑りを可能にした状態において組立
せられている点において共通の構成を有している。Therefore, both steel bands and link chains are
They have a common structure in that they are assembled in a state that allows them to slide relative to the block.

。Both of them are based on the technical concept of transmitting power by the thrust between the blocks.Since this is an invention, the steel band and link chain do not have the function of directly transmitting power;
It merely has the function of maintaining the shape of the (1) block in an endless band shape, and the relative slippage between the (2) block and the steel band and link chain was unavoidable.

。Means for Solving the Problems The present invention eliminates the technical idea of transmitting power by thrust between blocks, uses a link chain as a tension transmission medium, and furthermore, all tension transmission by the chain is a mesh transmission. The above-mentioned problems of the prior art were solved by changing the general technical idea that there is a chain link plate and using a chain to perform tensile friction transmission. and a friction transmission block piece having a through hole through which the end of the holding pin is inserted above and below the wire hole, respectively, is attached to both ends of the connecting pin, and the outer surface of the block piece is formed into a ■-shaped friction transmission slope, The friction transmission chain has holding pins above and below the connecting pin, both ends of which are inserted and fixed into the through holes.

ンを引張り駆動するものである。Function: Since the present invention has a large number of friction transmission block pieces attached and fixed to both ends of the link chain connecting pin, it is possible to create a boolean whose opposing surfaces are formed in a V-shape on the same axis and whose spacing between the opposing surfaces can be expanded or contracted. In a continuously variable transmission having a friction transmission block, when the friction transmission chain of the present invention is suspended endlessly between a pair of the pulleys arranged apart from each other, both outer surfaces of the friction transmission block are pressed against the opposing surfaces of the boot. The chain is pulled and driven through the chain connecting pin by frictional transmission between the pulley and the V-block.
