Power transmission roller

Japanese Patent JP6352148

B2

It is an object of the present invention to provide a power transmission roller assembly capably of stably transmitting power between a driving roller and a driven roller of a power transmission mechanism due to the friction therebetween, and to make the power transmission mechanism small-sized. Such a power transmission roller assembly includes a power transmission roller (2) configured to be brought into contact with the driving roller (D) and the driven roller (S), a pivot shaft (3) fixed to a vehicle body, a pivot arm (4) arranged radially inside of the power transmission roller (2), and pivotally mounted on the pivot shaft (3), a roller support bearing (5) rotatably supporting the power transmission roller (2), a pair of biasing members (6) mounted to the pivot arm (4), and biasing the roller support bearing (5) to a predetermined position between the driving roller (D) and the driven roller (S) such that the abutment force between the driving roller (D) and the power transmission roller (2) is balanced with the abutment force between the driven roller (S) and the power transmission roller (2), and sliding members (9) mounted on respective shafts (6a) of the biasing members (6) such that the shafts (6a) extend through the sliding members (9), and such that frictional forces are generated between the sliding members (9) and the respective shafts (6a).
