ABSTRACT:
A size adjustor is provided for adjusting the size of an article requiring size adjustment. The size adjustor includes a flexible belt having a flexible plate attached thereto. The flexible plate has teeth projecting outwardly therefrom and the teeth are arranged at a predetermined pitch. The teeth are arranged in two rows so as to form a channel part between the two rows. The size adjustor also includes an adjustment fixing member. The adjustment fixing member includes an operating plate which is rotatably supported on a main body. The main body includes a bottom plate with a hole therein. Two side plates are perpendicular to the bottom plate and two pivot support arms project upwardly from the side plates. The operating plate has a through hole therein and two perpendicular side walls. The side walls have operating plate supporting holes therein for engagement with the pivot support arms of the main body. A front end of the operating plate has an engaging claw which engages with the teeth projecting outwardly from the flexible belt. A rear end of the operating plate has a spring body part. The spring body part has a tip end which includes a curled portion. The curled portion is of a narrow width so as to fit within the channel part between the two rows of teeth.
