PURPOSE:To reduce the number of parts and simplify the structure by providing an axle locking mechanism itself with an unlocking function which is availabe when the axle is inclined. CONSTITUTION:When a fork is lifted over a certain height and a lead switch 16 of a liquid level sensor 20 is turned ON, a movable lock lever 26 is turned around the center of a pin 27 and an engagement projection 26a of the lever is fitted into an engagement hole 24a of a fixed lock plate 24. A rear axle 3 may be thus locked with respect to a frame 1a. When the rear axle is inclined where a fork lift stands on an inclined face, and the frame 1a is horizontal, even though the fork is lifted over a certain height and the solenoid 28 is therefore excited so that the movable lock lever 26 is turned toward the fixed lock plate 24, the engagement projection 26a, may not be fitted into the engagement hole 24a, thus the rear axle 3 may be hold in swingable state. |
