Abstract: The present invention relates to a trousers rack which uses the differences in the thickness of a thick upper portion and a thin lower portion above and beneath the waist seam line of trousers. The trousers rack of the present invention can be used in the following manner: a user holds the waist pair of the trousers with two hands, inserts the lower portion beneath the waist seam line into the gap between protruding support bars of hanging means, and releases the two hands from the trousers, such that the upper portion which is thicker than the lower portion beneath the waist seam line of trousers naturally gets caught between the support bars and the trousers can be hung on the trousers rack. The number of hanging means can vary as need, so as to increase or decrease a trousers storage space. Further, the width of the gap between the support bars can be adjusted in accordance with the thickness of trousers, thereby improving user convenience.
