摘要： A belt with improved ratchet type buckling means is disclosed. The belt has a pawl assembly vertically held between the top and bottom walls of the buckle and selectively engaging with a ratchet part. The pawl assembly has a rotatable cylinder, a pawl coupled to the cylinder and adapted for selectively engaging with the ratchet part. A vertically movable push rod is received in the cylinder such that the bottom of the push rod projects out of the bottom wall of the bucket. The cylinder along with the pawl is rotated to make the pawl disengage from the ratchet part when the push rod vertically moves up in the cylinder. In order to rotate the cylinder with the pawl, a radial projection of the push rod is received in an inclined slit formed on a side wall of the cylinder.
