Abstract: Provided is a roller assembly for a storage device. The roller assembly includes a shaft member, a rolling member, a cover member, and ball members. In particular, the ball members are configured to perform a rolling operation while being maintained in the state of being seated at specific locations by a seating groove formed in the shaft member and guide grooves formed in the rolling member and the cover member, and the rolling member and the cover member are configured to be coupled to each other by a fitting method and are then completely coupled to each other through laser bonding. The roller assembly is additionally characterized in that the damage of the ball members is prevented from occurring during the above laser bonding.

Abstract: Provided is a head assembly for a water purification filter, which includes a head body, a rotation shaft, and a fastening cap. In particular, the rotation shaft is rotated in the state of being placed on a seat protrusion formed on the head body, and a lower seal member is disposed in the portion where the rotation shaft is placed on the seat protrusion. Accordingly, there can be prevented a problem in which the lower seal member departs from a predetermined location during the coupling of the rotation shaft to the head body so that defective assembly occurs.

Abstract: A refrigerator may include a partition wall that isolate a first storage compartment from a second storage compartment. A third storage compartment is provided in the partition wall to be recessed downwards from an upper surface of the partition wall. An opening is formed on the upper surface to allow storage objects to be placed into the storage space. A door covers the opening of the third storage compartment and is configured to be moved in a direction parallel to the upper surface of the partition wall to selectively open or close the opening. An elastic-force assembly may apply a restoring force to the door when the door is moved to open the third storage compartment. A slide assembly that guides movement of the door may include a speed dampener that reduces a speed of the door when the door is moved to close the third storage compartment.
