PROBLEM TO BE SOLVED: To protect the periphery of an attitude holding hole while improving insertion/extraction properties of an attitude holding pin that holds a storage attitude and a development attitude.SOLUTION: An outrigger device 10 has: a plurality of attitude holding holes 16k, 16u, m and s which are configured so as to be positioned in a development attitude and a storage attitude by restriction and release of positions at which constituting members 16 and 19 are relatively moved by a manual operation of an operator, and pass each of the constituting members 16 and 19 coaxially with each other at a position corresponding to the respective attitudes; an attitude holding pin 41 that is inserted to and/or extracted from the attitude holding holes 16k, 16u, m and s at the position corresponding to the respective attitudes and restricts and releases each of the constituting members 16 and 19; and a pair of resin protective plates 61 and 65 having a trough hole that is mounted on each of both surfaces 16s in the outermost of the constituting members 16 and 19 and is formed so as to insert and extract the attitude holding pin 41 coaxially with the attitude holding holes 16k, 16u, m and s.SELECTED DRAWING: Figure 2
【課題】格納姿勢および展開姿勢を保持するための姿勢保持ピンの挿抜性を向上させつつ、姿勢保持穴周囲を保護する。【解決手段】このアウトリガ装置10は、構成部材16,19相互の相対移動する位置をオペレータが手動操作で拘束および解除することにより、展開姿勢と格納姿勢とに位置可能に構成され、各姿勢に応じた位置で構成部材16,19相互を同軸に貫通する複数の姿勢保持穴16k、16u,m,sと、各姿勢に応じた位置で姿勢保持穴16k、16u,m,sに挿抜されて構成部材16,19相互の位置を拘束および解除する姿勢保持ピン41と、構成部材16,19の最も外側の両面16sにそれぞれ装着されて姿勢保持穴16k、16u,m,sと同軸に且つ姿勢保持ピン41を挿抜可能に形成された挿通孔を有する樹脂製の一対の保護プレート61、65とを有する。【選択図】図2
