Abstract: An axle assembly is provided and includes an axle component, a pinion nut, and a retainer. The axle component has a recess that defines a wall portion. The pinion nut is received within the recess. The retainer is received within the recess and is disposed between the pinion nut and the wall portion. The retainer is movable between a compressed state and a first expanded state, whereby the compressed state permits movement of the retainer relative to the pinion nut and the first expanded state engages the pinion nut and the wall portion to restrict movement of the retainer relative to the pinion nut and the wall portion.

Abstract: A handgrip includes a tubular grip body having at least two angularly spaced-apart resilient clamp portions projecting outwardly and axially from an annular end thereof, a substantially U-shaped rod member having a bight portion, and non-threaded head and threaded end portions, and a sleeve ring sleeved around the resilient clamp portions and having first and second curved retaining grooves receiving respectively the resilient clamp portions, a head-receiving groove section receiving the non-threaded head portion, and a guide groove section receiving the threaded end portion. A nut member is disposed outwardly of the guide groove section, and engages threadedly the threaded end portion. The nut member pulls the threaded end portion when tightened so that the bight portion pushes one of the resilient clamp portions toward the other resilient clamp portion.
