Abstract: The present invention relates to a ceramic ball having a detergent function and a method for manufacturing a ceramic ball, which can improve washing capacity since the ceramic ball is molded such that the surface area coming into contact with water gets wider, and can improve production efficiency and reduce the manufacturing cost since it is possible to manufacture ceramic balls continuously and automatically.

Abstract: According to a steer-by-wire steering apparatus of the present embodiments, by means of offsetting a gap due to abrasion occurring in a rotation preventing member for preventing the rotation of a sliding bar as the sliding bar connected to wheels slide, noise is reduced, precision of a sensor for sensing the position of the sliding bar is enhanced, and sensor precision degradation due to moving or bending of the sliding bar can be prevented.

Abstract: A lead screw structure comprises a screw shaft having a thread on an outer circumferential surface thereof, a nut unit coupled to the screw shaft such that and a thread formed on an inner circumferential surface of the nut unit is engaged with the thread of the screw shaft, and a first elastic member disposed on a portion of the nut portion, in a direction of the screw shaft, to provide an elastic force to the nut portion in the screw shaft, thereby compensating for a gap between the thread of the outer circumferential surface of the screw shaft and the thread of the inner circumferential surface of the nut unit.

Abstract: The present invention relates to a washing ball case for a dishwasher. The washing ball contains a case body with an upper plate portion and a lower plate portion and has through holes formed in an outer side portion thereof so as to completely drain the washing water at the time of washing dishes.

Abstract: Disclosed is a planetary gear reducer for a vehicular steering apparatus. The planetary gear reducer includes: a sun gear, to which a steering shaft is joined; a planetary gear circumscribing the sun gear; a carrier, to which a rotary shaft of the planetary gear is joined; a ring gear, in which the planetary gear is inscribed; and backlash compensation members. The backlash compensation members are coupled to one or more of the sun gear, the planetary gear, and the ring gear such that the backlash compensation members are rotated in a state where they are in close contact with each other.

Abstract: The present invention relates to a washing ball case for a dishwasher, used to wash dishes by washing balls of a ceramic material and washing water without using any detergents and, more particularly, to a washing ball case for a dishwasher, wherein a case body (100) is formed by thermally bonding a top plate (10) and a bottom plate (20) and has through holes (120) formed in an outer side portion thereof so as to completely drain the washing water at the time of washing dishes such that the washing balls can be maintained in a dried state through the complete draining of the washing water and the washing efficiency of the washing balls can be maximized in next dish-washing, and through holes (120) and reference grooves (130) are provided to the outer portions of the top plate (10) and the bottom plate (20) such that, at the time of the thermal bonding, the top plate (10) and the bottom plate (20) can be bonded to each other at uniform positions in a fixed state without movement by the through holes (120) and
