PROBLEM TO BE SOLVED: To provide a safety device for a high lift work vehicle that solves the problem wherein withdrawal operation takes time due to the difficulty in the operation for withdrawing a work platform 6 of the high lift work vehicle positioned in a restricted zone S to a safety side. SOLUTION: This safety device for high lift work vehicle is provided with: a first determining means 38 which determines that the work platform 6 is positioned in the prescribed restricted zone S in response to signals from a work platform position detection means 31 and a prescribed restricted zone storage means 37 when the work platform 6 is positioned in the restricted zone S; a restriction means 39 which restricts the operation of the work platform when the first determining means 38 determines that the work platform 6 is positioned in the prescribed restricted zone S; a second determining means 40 which determines that the operation direction of a horizontal operation means 24 is not directed to the prescribed restricted zone S; and a releasing means 41 which releases the restriction of the restriction means 39 when the second determining means 40 determines that the horizontal operation means 24 is not directed to the prescribed restricted zone S.
