Abstract: A cooling structure includes a housing having a cooling channel defined therein through which a coolant flows and includes a sealing cap fitted to a hole of the housing to seal the hole. The sealing cap includes a blocking member configured to be in contact with an internal surface of the housing. The cooling structure may be for cooling a motor, such as an in-wheel vehicle motor.

Abstract: A channel structure includes a cooling channel continuously formed inside a housing. A coolant is configured to flow in the cooling channel. The cooling channel includes a plurality of channel portions spaced apart from each other and extending in the housing by changing directions.

Abstract: The present disclosure provides a sealing device and an in-wheel motor including the sealing device. The in-wheel motor includes a stator, a rotor rotatably disposed with respect to the stator, an annular inner seal connected to the stator and spaced apart from the rotor by a predetermined gap so as to be disposed between the stator and the rotor, and an annular slinger coupled to an end portion of the rotor, wherein the annular inner seal seals between the slinger and the in-wheel motor.

Abstract: The present invention relates to a method for molding a shape of bristles of a mascara brush for eyelashes, a mold in used in the method. Two strands of iron cores are twisted and brush bristles respectively having dorsal portions are radially spread between the twisted iron cores through post-process so as to form a mascara brush, wherein the dorsal portions are formed by the brush bristles of the same length on the basis of the iron cores without difference in the length of the brush bristles, so that a mascara solution contained in the dorsal portion does not run down when being applied to eyelashes, and the mascara provides more volume and a beautiful eyelash make-up when a sufficient amount of the mascara solution is applied.

Abstract: A mascara according to the present invention includes guards 34 disposed outside a brush with a predetermined gap theretbetween, in which the guards 34 can function as the teeth of a comb when the mascara is used and can prevent a mascara substance from gathering and block dirt.

Abstract: A mascara brush for eyelash makeup includes two strands of iron cores and brush bristles having dorsal portions, which are formed by nylon bristles put on the iron cores and twisted spirally several times so as to be formed radially on the basis of the iron cores, the brush bristles having the dorsal portions having the same length on the basis of the iron cores.

Abstract: A mold used for molding a shape of mascara brush bristles for eyelash makeup includes a dorsal portion molding hole enabling the dorsal portions of the brush bristles of the mascara formed by nylon bristles put on two strands of iron cores and twisted spirally several times so as to spread in all directions on the basis of the iron cores so that the brush bristles have a circular section, to be formed outwardly on the basis of the iron cores.
