PROBLEM TO BE SOLVED: To provide a grain tank, the inside of which can be easily inspected, though the tank is formed by resin molding and is reinforced.SOLUTION: A grain tank (30) is installed behind the drivers seat (20). An opening (52) is formed in the upper surface (41) of the grain tank (30), and is equipped with a lid (43) freely openable and closable. The lid (43) is equipped with a lock member (51) which keeps the lid (43) closed, and a transparent swelling part (43a) is formed in the lid (43) excluding the mounting part of the lock member (51). Moreover, a projection brim (43b) which projects to the inside of the grain tank (30) is formed in the lower peripheral part of the opening and closing lid (43). In the projection brim (43b), the part distant from the slot (44) extends further downward than the part of the slot (44) side, and the lower extending part of the projection brim (43b) faces the slot (44) to the inside of the grain tank (30).COPYRIGHT: (C)2013,JPO&INPIT【課題】グレンタンク内部の点検を容易化する。【解決手段】操縦席(20)の後側にグレンタンク(30)を設け、グレンタンク(30)の上面(41)には開口部(52)を形成し、開口部(52)に開閉自在な蓋(43)を設け、蓋(43)には、この蓋(43)を閉じ状態に保持するロック部材(51)を設けると共に、この蓋(43)におけるロック部材(51)の取付部を除いた部位に透明な膨出部(43a)を形成する。また、開閉蓋(43)の下側周縁部に、グレンタンク(30)の内側に向けて突出する突起縁(43b)を形成する。また、突起縁(43b)は、投入口(44)側の部位よりも投入口(44)から離れた側の部位を下方へ延出させ、この突起縁(43b)における下方延出部をグレンタンク(30)内への投入口(44)に対向させる。【選択図】図4
