PURPOSE:To prevent the abnormal abrasion of a roller by linear contacting the roller with a roller holding disc pivoted to an arm shaft. CONSTITUTION:An arm shaft 9 is fixed to one end of an arm 7 which is fixed to a vane fixing shaft (not shown) while a roller 28 is mounted through solid state lubricating members 32a, 32b to the arm shaft 9. Here the left and right side faces of the roller 28 will contact with a disc (not shown) of an actuator disc through solid state lubricating members 31a, 31b, but since both side faces of the roller 28 are planer the roller 28 will contact linearly with the disc during the rotating of the vane the facial pressure at the contact face can be reduced. |
