Abstract: The present invention provides tacrolimus containing ointment having low dermal irritation and excellent stability. It was found that an ointment comprising triacetin as a solubilizer for tacrolimus may sufficiently solubilize tacrolimus, has low dermal irritation and excellent stability. Preferably, the ointment of the present invention is an o/o type (oil-in-oil type) ointment in which tacrolimus-solubilized triacetin droplets are dispersed in an ointment base, preferably a mixture of beeswax and petrolatum.

Abstract: A resin-made gearing apparatus that includes a configuration in which only one tooth flank side of each tooth in one of a pair of gears is provided with an overhang section that is disposed on at least one end portion in a tooth width direction, and overhangs diagonally from the one tooth flank side toward the adjacent tooth side; an end portion in a tooth width direction of each tooth in the other gear is provided with a lightening section that is disposed in a tooth flank of each tooth on an end face on the side of the end portion corresponding to the overhang section of the one gear, so that when the opposite teeth of the pair of gears are meshed with each other, the overhang section of the one gear is elastically deformed and also the lightening section of the other gear is elastically deformed, to absorb a backlash.
