PROBLEM TO BE SOLVED: To provide a lashing device, a turnbuckle, and a bolt for the turnbuckle reducing time and labor for fastening the turnbuckle and releasing interference besides preventing the deformation and wear of a chain and the turnbuckle over a long period of time. SOLUTION: The outer end of one bolt 11 of the turnbuckle 7 is provided with a head 14 having an engaging ring 15 for inserting the chain 6, and a receiving part 16 engaging the chain 6 inserted through the engaging ring 15. The receiving part 16 is provided with a chain insertion groove 17 extending along the screw axis extension line of the bolt 11 and receding from one end face of the head 14 toward the other end face side with a width slightly larger than the wire diameter of each ring 8 of the chain 6 and a depth not less than the short outer diameter of each ring 8, and an engaging groove 18 receding outward from the inner peripheral surface of the engaging ring 15, orthogonal to the chain insertion groove 17 on the axis extension line of the bolt 11, and formed in shape corresponding to the circular arc part of each ring 8 of the chain 6.
