ABSTRACT:
A bicycle inflator includes a cylinder having a cap fixedly received in a first end thereof and an end member fixedly received in a second end of the cylinder. The cap has a passage defined therethrough. The end member has a tubular portion extending downwardly from a bottom thereof and the tubular portion has a cut-away defined through a periphery thereof so that a pawl member extending from the bottom is received in the cut-away. A piston rod extends through the end member and is connected to a piston member in the cylinder. A handle has a first end and a second end which is pivotally connected to the piston rod. A longitudinal recess is defined through a periphery of the handle and sized to allow the piston rod to pass therethrough. Each of two opposite inner sides defining the longitudinal recess has a notch defined therein and located near the first end so as to receive the pawl member when the handle is not used. Two protrusions respectively extend from the two respective opposite inner sides defining the longitudinal recess and are located near the second end of the handle.
