Document Type and Number:
Japanese Patent JP2019138344
Kind Code:
A
Abstract:
To provide a tension adjustment device which adjusts tension generated in a power transmission belt by increasing/decreasing the substantial length of the power transmission belt, which has a simple structure, which is easy for miniaturization and which can easily adjust tension, in a belt pulley mechanism which is constituted by winding the power transmission belt between a drive pulley and a driven pulley.SOLUTION: A tension adjustment device includes: a base 11; a first connection part 12 which is fixed to the base 11, and to which one end of a toothed belt 9 is connected; and a second connection part 13 which can adjust position in the direction in parallel with the movement direction of the toothed belt 9, which is mounted on the base 11, and to which the other end of the toothed belt 9 is connected.SELECTED DRAWING: Figure 2
