The present invention relates to a device for adjusting the length of a waist portion of bottoms, which is capable of easily adjusting the length of the waist portion of the bottoms (pants or a skirt) in correspondence to variations in body size. While the waist portion of the bottoms is divided into a front waist portion and a rear waist portion in each of both left and right sides, the front waist portion is formed overlapping an end of the rear waist portion, a guide rail in which a rack part is formed is installed on the rear waist portion, a moving member moving along the guide rail is installed on the front waist portion, so that the rear waist portion and the front waist portion are connected to each other, a latch elastically supported by a permanent elastic member and caught by the rack part is installed on the moving member, and the elastic member has a central portion wound in a coil configuration and coupled to a hinge shaft. One end extending from the central portion is bent in a shape corresponding to a pressing part to support a bottom surface of the pressing part, and the other end extending from the central portion extends in the direction of the pressing part and is then caught and fixed by a fixing piece bent from an upper side surface of the moving member towards an opening.

The present invention relates to a retainer ring structure for a CMP apparatus and a method for manufacturing the same. The retainer ring structure may include screws for fixing the retainer ring structure mounted on a polishing head during a CMP process, the screw being made of a high-strength metallic material, and the method for manufacturing the retainer ring structure may be simplified. Thus, a coupling force with the polishing head may be increased to reduce a defect rate, and the process may be simplified to reduce an operation time and a manufacturing cost, thereby increasing merchantability.

The present invention relates to a golf club shaft, and the purpose of the present invention is to provide a golf club shaft having an identifier formed on one side thereof to identify the location where a golf club is standing vertically on the ground, thereby enabling accurate green reading. To this end, the golf club shaft according to the present invention comprises: an upper part having a grip fixed thereon; a middle part of a predetermined length extending from the upper part; and a lower part extending from the middle part and having a head fixed thereon, wherein the middle part (24) is formed as a linear type to prevent a reference location from being changed even in the case where a golf ball comes into contact with one side of the golf club shaft when the golf club is standing vertically on the ground for green reading, and wherein the middle part (24) comprises an identifier (10) to identify the point where the golf club has a single center of gravity (C) when the golf club is stood vertically.

The present invention generally relates to a device for
adjusting girth of a waistband of pants or a skirt, in which
the device can efficiently adjust the girth of a waistband of
pants or a skirt in response to body changes such as a weight
gain or loss. To achieve the above-mentioned object, the
device of the present invention is configured as described
hereinbelow. The waistband of the pants or the skirt is
divided into a front waistband and a rear waistband, and the
front waistband overlaps the rear waistband at an end part of
the rear waistband. A guide rail is fixed to the rear
waistband, and the rear waistband and the front waistband are
connected to each other, and a latch engaging with a rack part
is mounted to a sliding member, wherein an elastic member is
fitted over a hinge pin at a middle part thereof.
