WORK MACHINE

To provide a work machine allowing fixation and fixation release of its air compressor to be easily carried out.SOLUTION: A work machine allows a wheel (12a) to be fixed between a wheel stopper (21) and a fixation block (25) by energizing a lever (23) in a fixation direction with an energizing member (28) rotated in the fixation direction from an overlapped state of a support shaft (22) on a virtual line (L2) connecting a fixation shaft (26) and a rotation shaft (27), and fixation of the wheel (12a) with the fixation block (25) to be released by energizing the lever (23) in a releasing direction with the energizing member (28) rotated in the releasing direction from the overlapped state of the support shaft (22) on the virtual line (L2).SELECTED DRAWING: Figure 6 【課題】エアコンプレッサを簡単に固定及び固定解除できる作業機械を提供する。【解決手段】固定軸（２６）及び回動軸（２７）を結ぶ仮想線（Ｌ２）上に支軸（２２）が重なる状態より固定方向に回動した付勢部材（２８）によって、レバー（２３）を固定方向に付勢して、車輪ストッパ（２１）及び固定ブロック（２５）の間で車輪（１２ａ）を固定し、仮想線（Ｌ２）上に支軸（２２）が重なる状態より解除方向に回動した付勢部材（２８）によって、レバー（２３）を解除方向に付勢して、固定ブロック（２５）による車輪（１２ａ）の固定を解除する。【選択図】図６
