PURPOSE:To enable differential lock to be securely carried out by one foot without any wrong operation by providing a front and rear wheel differential lock pedal capable of changing over front and rear wheel differential gear mechanisms to the differential lock condition. CONSTITUTION:Bevel rears 10, 10 mesh with differential side gears 5, 6 to constitute a front wheel differential gear mechanism 11, and bevel gears 26, 26 mesh with differential side gears 21, 22 to constitute a rear wheel differential gear mechanism 27. And a pedal shaft 45 is pivotably supported by bearings 44, 44 provided beneath a step 43. A lever body 47 having one end connected pivotably to a base 46b of a front and rear wheel differential lock pedal 46 is secured fixedly to said shaft 45. By pedalling this pedal 46 is pulled a control wire 49 to pivot a differential lock arm 18 and differentially lock only said mechanism 11. By further pedalling the pedal is differentially locked said mechanism 27.
