摘要： A geared two-speed landing gear mechanism for semi-trailers is disclosed, of the type in which a hand-crank shaft is movable axially to select two gear ratios. A detent mechanism for defining the shaft position includes an elongated C-shaped spring clip which selectively engages one of a pair of grooves on the shaft. A clip retainer is formed on one wall of the gear casing and includes a pair of bent-wire retainers which are stud-welded to the wall at opposite sides of the shaft opening defining an access space therebetween for the insertion or the removal of a shaft-supporting bearing. The retainers have laterally turned ends which engage the clip to restrain it against axial movement. The retainers also support the clip in an aligned condition for ease in the insertion or removal of the shaft.
