PURPOSE:To produce a specified friction force with a simple construction by using a friction force which is generated by a friction force generating member equipped on a transmission that transmits the driving force of a driver to air deflector plates. CONSTITUTION:When a cam 19 turns on a cylindrical member 20, the rotating motion is transmitted to two elastic members 18 by the friction force, so that a link 13 is turned together with the cam 19. When the link turns on the elastic members 18 and an axle 14, a connecting member 10 reciprocates to the left and right as a protrusion 16 on the rear end of the link 13 is fitted into a slit 11a of a guide 11. Two or more rigid parts 5 on the rear side are connected with each other by the connecting member 10. Therefore, the rigid parts 5 are reciprocated to the left and right together with the connecting member 10. At this time, flexible parts 3 expand in the opposite direction to that of the reciprocating movement of the rigid parts 5 since air deflector plates 2 are rotatably mounted on a main body 1 at rigid parts 4 on the front side. |
