Claims

[Scope of utility model registration request]

A telescopic arm 1 has an outer cylinder 2 fixed to the carrier side and an inner cylinder 3 telescopically inserted into the outer cylinder 2. A ground plate 6 is attached to the tip 3a of the inner cylinder 3. This is an outrigger device in which a jack cylinder 5 is attached to the inner cylinder 3 in a non-tilting state, and the ground plate 6 is connected to the lower end 5a of the jack cylinder 5 so that the arm 1 is extended and contracted by a guide member 8. While it is possible to slide in the direction,
A base side rod 21 is provided near the side of the jack cylinder 5 and has an upper end 21a pivoted to a proper position of the inner cylinder 3 or a member integrated with the inner cylinder 3, such as a fixing member of the jack cylinder 5. and a tip side rod 22 which is telescopically fitted to the base side rod 21 and whose lower end 22a is connected to the ground plate-6.
A telescoping rod device 7 is installed between the jack cylinder 5 and the telescoping rod device 7, and when the jack cylinder 5 is retracting, the lower end of the tip side rod 22 is moved in conjunction with the retracting operation. The arm 1 together with the ground plate 6
The telescopic rod device 7 is tilted in the arm retracting direction so as to be moved relative to the arm in the arm retracting direction. The invention is characterized by being provided with a telescopic rod tilting device 9 that tilts the telescopic rod device 7 in the direction of extension of the arm so as to move the telescopic rod device 7 together with the ground plate 6 relative to the arm 1 in the direction of extension of the arm. outrigger device.
