Abstract

PURPOSE:To carry out accurate sensing of rolling, by drivably connecting movement of left and right lower links respectively to a cam surface and sensor arm and sensing a relative rolling angle. CONSTITUTION:Vertical rotation of one lower link 4 is transmitted through a crank rod 29 and an arm 8 to a sensor shaft 9 to rotate a cam disk 6. Vertical rotation of the other lower link 3 is transmitted through a crank rod 30 and a sensor arm 8 to rotate the sensor arm 8 about the sensor shaft 9. An operator 31 of a rolling sensor 7 is in slide contact with a cam surface 5 of the cam disk 6 facing the sensor arm 8 to sense a rolling angle by a difference in vertical rotation height of the left and right lower links 3 and 4.
