PROBLEM TO BE SOLVED: To avoid making a saw plate play in any direction such as front and back, left and right and up and down directions to a grip and to conveniently replace the saw plate in a hand-operated saw wherein the saw plate is inserted into the slit of the grip. SOLUTION: A large diameter part and a small diameter part are formed at different rotational positions on the circumference of a fixed shaft 30 provided on a grip 10 and the small diameter part of the fixed shaft is passed through a guide channel of a saw plate up to a through-hole to stop the saw plate come out by means of the large diameter part by rotating the fixed shaft. In addition, the slit 11 of the grip is tightened and loosened in the width direction by a cam 41 and cam receivers 14 and 15 with rotating the fixed shaft.
