A handle unit for a retractable handle assembly of a luggage case, said handle unit comprising:
- an elongate upper cap member having an upper wall that extends in a longitudinal direction, and a surrounding wall that extends from a periphery of said upper wall in a transverse direction transverse to the longitudinal direction and that cooperates with said upper wall to form a downwardly opening receiving chamber, said upper wall being formed with a cutout and a pair age of downwardly extending hollow posts that are disposed at opposite sides of said cutout, that are spaced apart from each other in the longitudinal direction, and that are threaded internally, said upper cap member further having opposite longitudinal ends formed with a respective screw hole that opens downwardly, said surrounding wall having a connecting end connected to said upper wall, a distal lower end face opposite to said connecting end in the transverse direction, and an inner wall surface formed with a protrusion that protrudes into said receiving chamber and that is disposed between said connecting end and said distal lower end face;
- an elongate press member disposed in said receiving chamber and formed with a pair of first through holes that permit said hollow posts to extend slidably and respectively therethrough, and a pair of link actuating ends that extend toward said longitudinal ends of said upper cap member, respectively;
- an elongate base member formed with a pair of second through holes that are registered respectively with said hollow posts, a pair of third through holes that are registered respectively with said screw holes, and a pair of openings that extend in the transverse direction and that permit access to said link actuating ends, respectively, said base member having an upper peripheral part with a distal upper end face and a peripheral shoulder disposed around and spaced apart from said distal upper end face in the transverse direction, said upper peripheral part being fitted into said receiving chamber such that said upper peripheral part mates with said surrounding wall, with said distal upper end face abutting against said protrusion and with said distal lower end face abutting against said shoulder;
- a pair of biasing members, each of which is sleeved on a respective one of said hollow posts and has an upper end abutting against said press member, and a lower end abutting against said base member;
- a pair of first screw fasteners, each of which extends through a respective one of said second through holes and engages threadedly a respective one of said hollow posts;
- and
- a pair of second screw fasteners, each of which extends through a respective one of said third through holes and engages threadedly a respective one of said screw holes.
