PROBLEM TO BE SOLVED: To solve problems in a prior waist belt which, for example, the prior waist belt covers a range from a lumbar spine to a sacrum when being wound around users waists, and is formed of a single belt, so that the prior waist belt is not suitable for making a waist and a pelvis slender.SOLUTION: A diet belt for waist parts is wound around users waist parts with a winding belt, in which three belts which are divided into three in a vertical direction are connected, and which covers a range from breast lower parts to waist parts 7 reaching to a pelvic part 8. The first belt 1 is configured so that, weaving of the first belt is weakened for reducing tightening force on parts corresponding to at least breast parts, the second belt 2 is woven so as to increase tightening force and covers the pelvic part 8, and the third belt 3 is woven so as to increase tightening force and covers a greater trochanter 10 part. Both ends of the first to third belts comprise male surface fasteners 4 and female surface fasteners 5, for fixing, and the diet belt for waist parts can cover a wide range.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 従来技術の腰ベルトは、腰に巻いた際、腰椎から仙骨にかけての範囲を覆うもので、しかも1枚のベルトで形成したものであるため、ウエストと骨盤を細くするためには好適なものではない【解決手段】 巻付帯により腰部に巻かれるウエスト部のダイエットベルトで、上部から3つに分割した3枚のベルトを接続し、乳房下部から骨盤部8に至るウエスト部7を覆う腰ベルトであって、少なくとも乳房に当たる部分は締め付け力を弱くするためにベルトの編み方を弱くした第1ベルト1に、続いて骨盤部8を覆う締め付け力を強くした編み方の第2ベルト2を接続し、さらに大転子10部分を覆う締め付け力を強くした編み方の第3ベルト3を接続し、これら第1~第3ベルトの両端には雄、雌面ファスナー4、5を設けて固定できるようにし、広範囲を覆うようにしたウエスト部のダイエットベルト。【選択図】図2
