PROBLEM TO BE SOLVED: To provide an outrigger device used in a high place work device.SOLUTION: The outrigger device includes an opening/closing mechanism (9) capable of opening and closing an auxiliary leg (10) to a column side member (4P), and a lock mechanism (26) capable of locking the auxiliary leg (10) at a leg closing position and a leg opening position. An upper side arm (8a) of the opening/closing mechanism turns an arm posture from a first pivot (20) pivoted to the column side member (4P) to a second pivot (21) pivoted to the auxiliary leg (10) to a leg closing posture (P1) which is an upward posture along the auxiliary leg (10) when the auxiliary leg (10) is closed, and turns the arm posture to a leg opening posture (P2) which is a downward posture along the auxiliary leg (10) when the auxiliary leg (10) is opened. The lock mechanism (26) includes an operation member (27) provided on the auxiliary leg (10) movably between a lock position (L) and an unlock position (U), and leg closing lock means (29) and leg opening lock means (30) for mutually non-turnably locking the operation member (27) and the upper side arm (8a). |
