A caster swivel lock construction comprising a base, a yoke rotatably mounted on the base for rotation about a vertical axis and having a ring plate and spaced legs extending away from the ring plate, an axle extending between the legs and a wheel rotatably mounted on the axle. The ring plate has one or more radially extending notches therein. A spring loaded plunger assembly is mounted on the base and comprises a body, a plunger movable axially in the body, and a spring associated with the plunger. A foot pad is pivoted to the plunger on the other end and has a cam portion urged by the spring to engage a portion of the body so that the plunger is moved axially inwardly and outwardly by operation of the foot pad. The plunger assembly is removably mounted on the base so that the plunger axis extends radially inwardly toward the ring plate and movement of the foot pad causes the plunger to move radially inwardly and outwardly for engagement and disengagement with a notch. The cam portion of the foot pad has a configuration such that in one position of the foot pad, the one end of the plunger is out of engagement with a notch, and in another position, the one end of the plunger is in engagement with a notch.
