PROBLEM TO BE SOLVED: To provide a combine harvester 1 in which a single side cover 23 covers front faces of a radiator 31 and an air cleaner 26 and the side cover is made of a resin to reduce weight of the side cover 23 and simplify the structure thereof while improving maintenance property of the radiator and the air cleaner.SOLUTION: In a combine harvester, a side cover 23 has a resin frame body 51 to which dust-proof bodies 56, 57, metal fittings 43, 44 and a seal material 59 are attached and a grip 54 is integrally molded with an outer peripheral edge of the frame body. The side cover is opened by hooking the grip with a finger and pulling it outward of the body to expose front faces of a radiator and an air cleaner to the outside.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】ラジエータ31とエアクリーナ26の前面を単一のサイドカバー23で覆うと共に、このサイドカバーを樹脂製にして、ラジエータとエアクリーナの整備性の向上を図りながら、サイドカバー23の軽量化と構成の簡素化を図ることができるコンバイン1を提供する。【解決手段】サイドカバー23は、樹脂製となす枠体51に防塵体56、57と取付金具43、44とシール材59を装着すると共に、該枠体の外周縁に取っ手54を一体成型し、この取っ手に指を掛けて機体外方に引くとサイドカバーが開いて、ラジエータとエアクリーナの前面が露出するように構成する。【選択図】図5
