Abstract: An absorbent article includes a liquid-permeable topsheet, a liquid-impermeable antileakage sheet, a liquid-retentive absorbent core, having a substantially elongate shape, and having upstanding guards formed on longitudinal left and right opposing side portions of the absorbent article, the upstanding guards are provided with a plurality of upstanding guard elastic members so as to form a gather over the entire region in the widthwise direction of the upstanding guard, the upstanding guard is sectioned into a free end region, a central region and a basal end region so as to trisect it in its widthwise direction, and the stress of the free end region is larger than that of the other regions.

Abstract: A drive belt for use in a continuously variable transmission has an endless carrier and a plurality of elements. The endless carrier has a plurality of endless metal belts with plank-shaped cross sectional shapes laminated together in both radial and axial directions to form ring aggregates. The ring aggregates reduce the rigidity of the endless carrier in the axial direction and increase the allowable axial deflection endless. Thus, when off-centering occurs, the entire V-belt does not become slanted with respect to a line perpendicular to the rotational axes of the pulleys and the V-shaped blocks can be prevented from becoming tilted with respect to the pulley. As a result, the durability of the pulleys and V-shaped blocks can be improved. The entire V-belt becomes slanted when off-centering occurs in a V-belt continuously variable transmission.
