PURPOSE:To assign different positions of a steering lever in response to three conditions ''to be locked'', ''locked'' and ''lock removed'' by supporting with a common pin shaft a power input lever which is connected to a steering lever and a lock cam which works on a hook engaged with a lever on a chassis side end providing a latch click for the ''lock removed'' condition. CONSTITUTION:''Locked'' condition is removed by pulling a steering lever 2. A junction of said lever 2 and a power input lever 9 is located in a point AL under the ''locked'' condition and this point is transferred to a point AR by pulling the lever 2. A condition under which the junction is located in the point AR is the ''lock removed'' condition under which a latch click 8 prevents swing of a lock cam 7. The ''lock removed'' condition is transferred to the ''to be locked'' condition with a cabin being titled by a hydraulic pressure cylinder and the like used for tilting. |
