To provide an outrigger device in which an occupied area of an outrigger cylinder is reduced, so that an occupied area of the outrigger device is reduced when stored.SOLUTION: An outrigger device 9 comprises: a base end side arm 93; a nested tip side arm 95 with its base end part pivoted to a tip of the base end side arm; a boomerang type link 100 with one end part attached to a horizontal shaft in a freely rotatable manner in a position near the tip of the base end side arm 93; and a lateral outrigger cylinder 36 which is arranged inside the tip side arm 95, and of which an end part on a cylinder rod 36b side is supported in a position near a tip of the tip side arm 95, and of which an end part on a cylinder tube 36a side is supported by a horizontal shaft in a freely rotatable manner at the other end part of the boomerang type link 100. The boomerang type link 100 is constituted so that elongation and contraction force of the lateral outrigger cylinder 36 is converted to turning force for the base end part of the tip side arm 95 and transferred to the base end part.SELECTED DRAWING: Figure 6

    【課題】 アウトリガシリンダの専有面積を低減することで、格納時のアウトリガ装置の専有面積を低減することが可能なアウトリガ装置を提供する。【解決手段】 このアウトリガ装置9は、基端側アーム93と、その先端部に、基端部が枢支された入れ子状の先端側アーム95とを備え、基端側アーム93の先端寄りの位置に一端部が水平な軸回りに回転自在に取り付けられたブーメラン型リンク100と、先端側アーム95の内側に配設されていると共に、先端側アーム95の先端寄りの位置にシリンダロッド36b側の端部が支持され、ブーメラン型リンク100の他端部にシリンダチューブ36a側の端部が水平な軸回りに回転自在に支持された横アウトリガシリンダ36とを備え、ブーメラン型リンク100は、横アウトリガシリンダ36の伸縮力を先端側アーム95の基端部の回動力に変換して該基端部に伝達するように構成されている。【選択図】図6
