<p>An object of the invention is to provide a waist adjusting device, in which the number of components is reduced, an assembly thereof is not necessary because of its simple structure so as to achieve reduction of production cost and the adjustment operation is very simple. An adjusting belt (1) has a multiplicity of adjusting protrusions (11) on the surface thereof and a slider (2) has a through portion (20) which the adjusting belt (1) can be passed through in the right and left direction. Engaging protrusions (24) which are capable of engaging the adjusting protrusions (11), when the adjusting belt (1) is passed through an upper section of the through portion (20), are provided on both sides of an inner face of a through hole (23) provided on a rear plate (22) thereof. Attaching holes (27) whose inner side is expanded are provided in a surface plate (21) and a fixing device (4) has two attaching posts (42), which are inserted into the attaching holes (27) and fixed by crushing, at a rear face of a cap (41). Attaching posts (42) are pierced into a waist belt (6) and crushed in the attaching holes (27) so as to fix the slider (2). After the slider (2) is attached on the adjusting belt (1), the adjusting belt (1) is attached to the waist belt (6). By moving the slider (2) downward together with the waist belt (6), engagement therebetween is released. After adjustment is completed, the slider (2) and waist belt (6) are returned to their original positions. <IMAGE></p> |
