Abstract:
A ball retainer for a slide apparatus and a mold for manufacturing the same. The ball retainer includes, in a width direction, a first extension part and a second extension part that are extended from a center line, forming a pre-determined angle with each other, in a length direction, a body part formed in the center, and a pair of holding parts. Each holding part is respectively formed at each end of the body part. Each holding part includes a plurality of ball insertion grooves for inserting balls that are spaced apart in the length direction. Expansion parts each having an expanding cross-sectional area are respectively formed at both sides in the length direction of the first extension part and the second extension part.
Abstract:
A roller unit having an integrated fastening portion includes a supporting shaft fastened to a containing body or a containing main body that can slide and having first and second flanges formed in multi steps with different outer diameters, a rotating body rotatably fixed to a side of the supporting shaft, and a washer coupled to a side of the rotating body to surround and fix the second flange, thereby preventing separation of the supporting shaft and the rotating body. Therefore, it is possible to more conveniently combine the supporting shaft and the rotating body and to prevent separation of the supporting shaft and the rotating body, whereby is possible to improve various functions.
