Abstract: 67 DISPOSABLE DIAPER 5 The present invention aims to provide a wearing tide improved to prevent an undesirable step from being f to downward displacement of a front end flap of a absorbent chassis during use of the diaper, to prevent b y waste from leaking out and to assure a good appearance.10 At least the front waist region 213 of the front and rearwaist regions 213, 214 includes elastici ad regions 225, 226, 227 extending at least in the transver e direction Y, wherein the elasticized regions 225, 226 227 comprise a first elasticized region 225 defined between a waist-opening'15 peripheral edge 223a and the vi inity of a front end flap of the absorbent chassis 212 so as to extend in the transverse direction Y, a second elast ized regions 226 defined adjacent the first elasticized r-gion 225 so as to extend in the transverse direction Y snd a pair of third elasticized regions20 227 defined adjacen the second elasticized region 226 and spaced from and op sed to in the transverse direction Y on both sides of a non-e asticized region 228A formed in a transverse middle of thr front waist region 213 wherein the second elasticized region 226 extends across the front flap of ne absorbent chassis 212.Figure 1. -67- The present invention aims to provide a wearing article improved to prevent an undesirable step from being formed due to downward displacement of a front end flap of an absorbent chassis or upward 5 displacement of a absorbent core during use of the diaper, to prevent body waste from leaking out and to assure a good appearance. At least the front waist region 313 of the front and rear waist regions 313, 314 includes elasticized regions extending at least in the transverse direction Y, the elasticized regions10 comprise a first elasticized region 333 defined between a periphery of the waist-opening 316 and a front end of the absorbent chassis 312 inclusive of the front end flap 362 so as to extend in the transverse direction Y, a pair of second elasticized regions 334 defined adjacent the first elasticized region 333 so as to 15 extend from opposite side edges 318c of the front waist region313 to opposite side edges of a front end 347 of the absorbent panel 346 and to be spaced from and opposed to each other in the transverse direction Y on both sides of a first non-elasticized region 340A defined in a transverse middle of the front waist region 20 and a pair of third elasticized regions 335 defined adjacent the second elasticized regions 334 so as to extend from the opposite side edges 318c of the front waist region 313 to the opposite side edges of the front end 347 of the absorbent panel 346 and to be -68-spaced from and opposed to each other in the transverse direction Y on both sides of the first non-elasticized region 340A, and the first elasticized region 333 extends across the front end of the absorbentpanel347, wherein elasticized regions in the rear waist 5 region comprise a fourth elasticized region 336 defined between opposite side edges of the rear waist region so as to extend along the periphery of the waist-opening in the transverse direction, a fifth elasticized region 337 defined adjacent the fourth elasticized region 336 so as to extend to the rear end 346b of 10 the absorbent panel 346, a pair of sixth elasticized regions 338 defined adjacent the fifth elasticized region 337 so as to be spaced from and opposed to each other in the transverse direction on both sides of a second non-elasticized region 340b formed in a transverse middle of the rear waist region, and a pair of seventh 15 elasticized regions 339 defined adjacent the sixth elasticizedregions 338 so as to be spaced from and opposed to each other in the transverse direction on both sides of the second non-elasticized region 340b, wherein the seventh elasticized re 'ions 339 have a tensile stress lower than a tensile stress of 20 each of the fourth to sixth elasticized regions 336, 337, 338.
