PROBLEM TO BE SOLVED: To provide a combine provided with a side cover part for covering a power transmission device provided on the lateral outer side of a machine of a threshing device from the lateral outer side of the machine, and dust entering a gap between the threshing device and the side cover part. While making the water fall from the gap, it is difficult for the mud splashed up by the crawler traveling device to enter the gap between the threshing device and the side cover portion. SOLUTION: A lower cover portion 60 is provided to cover a gap between a lower end portion of a side cover portion 50 and a lower end portion 8f of a threshing device 8. A plurality of tilting members 68 are provided in a portion 63 of the lower cover portion 60 located above the rear end side portion of the crawler traveling device 2. The plurality of inclining members 68 are provided in a state of being inclined in a side view of the machine body and with a space S provided in the machine body front-rear direction, and dust is downward from a gap between the side cover portion 50 and the threshing device 8. It allows the crawler traveling device 2 to catch up the mud while allowing it to fall. [Selection diagram] Figure 8【課題】脱穀装置の機体横外側方に設けられた動力伝達装置を機体横外側から覆う側部カバー部が備えられたコンバインにおいて、脱穀装置と側部カバー部との間の隙間に入り込んだ塵埃が隙間から落下するようにしつつ、クローラ走行装置に跳ね上げられた泥土を脱穀装置と側部カバー部との間の隙間に入り込み難くする。【解決手段】側部カバー部５０の下端部と脱穀装置８の下端部８ｆとの間の隙間を覆う下部カバー部６０が備えられている。下部カバー部６０のうち、クローラ走行装置２の後端側部分の上方に位置する部分６３に、複数の傾斜部材６８が備えられている。複数の傾斜部材６８は、機体側面視において傾斜した状態、かつ、機体前後方向において間隔Ｓを空けた状態で備えられ、側部カバー部５０と脱穀装置８との間の隙間から下方へ塵埃が落下するのを許容するとともに、クローラ走行装置２が跳ね上げた泥土を受け止める。【選択図】図８
