PROBLEM TO BE SOLVED: To improve the maintenance and durability of a grain sieve, without causing the structure to become complex and weight-enhancing of a swinging selection mechanism. SOLUTION: The structure for attaching or detaching the grain sieve in a thresher, equipped with the grain sieve 24 capable of sieving grains from a treated product after threshing treatment and installed so as to be present over the right and the left sidewalls 53 and 54 of the swinging selection mechanism 11 is constituted, such that an engaging part 55, enabling the engagement with the right terminal part of the grain sieve 24, is formed at the lower edge part 53A of the right sidewall 53 of the swinging selection mechanism 11; and linking parts 54B and 57, enabling the link with the left terminal part of the grain sieve 24 with a linking tool 62, are formed at the right sidewall 53 so that the grain sieve 24 is constituted detachable to the bottom part of the swinging selection mechanism 11. An opening 34A, that allows the grain sieve 24 to be taken out and put in, is formed in the left side wall 34 of the thresher, and the opening is equipped detachably to a lid body 63 for closing the opening 34A.
