Claims

[Scope of utility model registration request]

It consists of a chain made up of links connected endlessly by pins, and a V-shaped block placed between each link node and in contact with a pulley.The link is inserted into the window of the V-shaped block to absorb the force from the pulley. In a V-type chain belt for power transmission that transmits power to a chain via blocks, each block is provided with a plate-shaped rattling member supported by a pin, and each rattling member is made of a shape memory alloy. , has a shape that makes it easy to insert the link into the block when the chain is assembled, and when in operation exerts a biasing force such that the outer side surface of the chain in the left and right direction comes into contact with the inner inner surface of the window part of the block in the left and right direction. A V-type chain belt for power transmission that is characterized by its shape.
