Abstract
A net chair-back includes a first frame member, a second frame member corresponding to the first frame member and combined with the first frame member, and a net member arranged between the first frame member and the second frame member. The first frame member includes a recessed groove formed therein and arranged in a circumferentially surrounding form. The recessed groove includes a plurality of fixation posts mounted therein. The second frame member includes an insertion groove formed therein and arranged in a circumferentially surrounding form. The insertion groove includes a plurality of locking pillars formed therein. The locking pillars each include a retention member mounted thereto. The retention member is tightly engageable with an inside surface of the fixation post. In this way, exposing locking holes or threaded fasteners outside the net chair-back can be prevented to thereby improve the outside appearance of the net chair-back.
