PROBLEM TO BE SOLVED: To easily adjust the height of a snowplow part by releasing the lock of a machine body with good operability without removing hands from handles. SOLUTION: This tilt mechanism is provided for a snowplow 1 having a pair of right and left handles 40 attached to the rear of a body 2 and a snowplow part 5 at the front of the body 2, with the entire body 2 supported in such a way as to be vertically rotatable about a drive shaft 35. The tilt mechanism comprises a tilt rod (lock means) 45 for locking the rotation of the body 2 about the drive shaft 35 and a tilt lever 56 which is rotated for undoing the locking of the body 2 by the tilt rod 45. Each handle 40 comprises an inclined part 40a and a horizontal part 40b. A grip 52 for gripping by an operator is provided at the rear end of the horizontal part 40b and a bracket 72 is fixed near the front of the grip 52 of the horizontal part 40b of one of the handles 40. The tilt lever 56 is rotatably journaled to the bracket via a shaft 58 and the part 56a of the tilt lever 56 extending backward from the shaft 58 is opposed to the grip 52 via a space. |
