Claims

[Scope of utility model registration request]

a fixed side support bracket having a first support wall portion and a second support wall portion parallel to each other; a first rotating shaft rotatably supported by the first support wall portion; a long hole formed in the support wall; a displacement-side support bracket supported on the outer surface of the second support wall so as to be freely displaceable in the length direction of the long hole; rotatably supported and supported by a second rotating shaft inserted through the elongated hole and an intermediate portion between the second rotating shaft;
A circular member that rotates together with the second rotating shaft and transmits power between the endless transmission member stretched around the outer periphery, and the first and second supporting walls. a universal joint connecting an end of one rotating shaft and an end of a second rotating shaft; and a fixing member fixed to the fixed side support bracket in a state protruding from a side surface of the second supporting wall. A side coupling plate, a displacement side coupling plate fixed to a part of the displacement side support bracket in a state opposite to the fixed side coupling plate, and this displacement side coupling plate and the above fixed side coupling plate are coupled together. 1. A tension adjustment device for an endless transmission member, comprising a screw member, the distance between the displacement side coupling plate and the fixed side coupling plate being adjustable as the screw member rotates.
