The second layer contains a polyethylene resin (PE) having 70 to 90 wt% of a lower crystalline component (LCC) and 10 to 30 wt% of a higher crystalline component (HCC). The PE has a melt flow rate of 0.1 to 20 g/10 min and in a temperature rising elution fraction elution curve, an elution peak temperature of the LCC is from 45 to 85° C; the ratio of (peak height of LCC)/(height of the minimum valley between LCC peak and HCC peak) is 9 or more; an area ratio of the elution peak temperature or less of LCC is 35% or more. The third layer contains a) PP or b) a high-pressure low density PE having an extrapolation melting completion temperature of melting of 110° C or more; or c) a copolymer of ethylene/C3-18 &agr;-olefin having a density of 0.920 g/cm3 or more.

A differential includes a pinion shaft holder, a differential case, a first side gear, a second side gear, a first spring and a second spring. The differential case includes a first side boss portion and a second side boss portion. The first spring is interposed between the first side boss portion and the first side gear. The second spring is interposed between the second side boss portion and the second side gear. A recessed portion is provided on the pinion shaft holder and is configured to avoid interference with an auxiliary tool. The auxiliary tool maintains one of the first spring and the second spring in the compressed state.

An antioxidant agent capable of easily enhancing the intake of ORAC (Oxygen Radical Absorbance Capacity) is proposed. The antioxidant agent includes tealeaf as an active ingredient for enhancing ORAC. The tealeaf is preferably plucked from tea Camellia sinensis, decaffeinated or in a powdery form having a median diameter equal to or less than 50 μm. A beverage using such antioxidant agent is also proposed.

A planetary gear device including a first gear, a second gear, a carrier, and composite planetary gears each having a large- and a small-diameter pinion that are formed integrally with each other and arranged in the axial direction. The composite planetary gears are mounted rotatably on respective pinion shafts such that the composite planetary gears are axially movable over predetermined distances due to axial plays, and the pinion shafts are supported by the carrier such that the pinion shafts are disposed around an axis of the carrier. The pinions of the composite planetary gears mesh with the first and second gears, respectively. Each of the first and second gears and the pinions consists of a helical gear whose teeth have a helix angle with respect to the axis. The large-diameter and small-diameter pinions have the same direction of helix and the same amount of lead.
