PROBLEM TO BE SOLVED: To obtain a support device, which supports an exhaust emission control system in a state where the exhaust emission control system is less likely to be affected by engine cooling air, in a structure which is easily used as a harvesting machine.SOLUTION: A support device 15 of an exhaust emission control system 12 includes: an attachment bracket 20 connected with a side surface of a crank case and a support medium 30 supported by the attachment bracket 20. The attachment bracket 20 includes: an upper connection part 22 connected with the support medium 30 in an area above a fly wheel 83 and a side connection part 21 connected with the crank case. The upper connection part 22 is located at a position which faces an upper side outer periphery part of the fly wheel 83 in a radial direction of the fly wheel 83. The side connection part 21 is formed so as to expose the outer periphery part of the fly wheel 83 to the outer side in the radial direction.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2016,JPO&INPIT【課題】エンジン冷却風による影響が及び難い状態で排気ガス浄化装置を支持する支持装置を、収穫機として用い易い構造で得る。【解決手段】排気ガス浄化装置12の支持装置15は、クランクケースの側面に連結される取付ブラケット20と、取付ブラケット20に支持された支持体30とを備え、取付ブラケット20は、フライホイール83の上方側で支持体30が連結される上方連結部22と、クランクケースに連結される側方連結部21とを備え、上方連結部22は、フライホイール83の上方側の外周部にフライホイール83の径方向で対向する位置にあり、側方連結部21は、フライホイール83の外周部を径方向外方側に露出させるように構成されたものである。【選択図】図11
