An umbrella frame device includes a runner (20,200) slidably sleeved on a stem (10,10",100) for spreading and collapsing a canopy. A retaining member (22,22',22",220) has a retaining end (222,222',222") which is movable radially in a slot (24,250) in the runner (20,200) and which is extendable inwardly of the runner (20,200) to slidably contact a slideway on a protuberance (113) disposed on the stem (10,10",100). The retaining end (222,222',222") is brought to slip over an upper edge of the protuberance (113) so as to be retained on a shoulder (13) when the runner (20,200) is moved to an engaging position. A sleeve member (30,30",300) surrounds and is movable relative to the runner (20, 200) , and has a cam surface portion (31,31",310) which can depress the retaining end (222,222',222") radially with a friction force that arrests the runner (20,200) in the engaging position. <IMAGE>
