A wheelbarrow having its wheel, legs and handles foldable against the underside thereof, for compact storage, comprising in combination: a. a barrow body having a flat bottom and upwardly inclined forward and rear walls; b. a base bracket mounted at the forward end of the underside of the body, at the longitudinal centerline thereof; c. a table tiltably mounted on the base bracket, for fore and aft movement relative to the barrow body centerline; d. a wheel fork, including a wheel journaled therein and a flat camming surface, pivotally mounted on the table and normally spring-biased to a first position, wherein the wheel is positioned crosswise of the barrow body longitudinal centerline; e. a pair of legs and handles hingedly mounted at the rear end of the barrow body underface, and swingable between a first, erected, position and a second, folded, position wherein they lie flat against the underface of the barrow body; f. lock means mounted on the barrow body rear wall, engageable with the handles to maintain them in their first position; g. a first pair of tie rods connecting the tiltable table to the legs, one of the tie rods having a cam positioned at the forward end thereof, adjacent the table; h. a second pair of flexible tension means connecting the legs to the handles; i. when in their, first, erected position, the handles act through the flexible tension means and the tie rods to maintain the legs in their first, erected, position with the table tilted rearwardly, causing the tie rod cam to engage the wheel fork camming surface, to pivot the wheel fork, and its supported wheel, to a second position, wherein the wheel is in a dependent position aligned with the longitudinal centerline of the barrow body; and j. when the handles and legs are in their second, folded, position The tie rods act to tilt the table forward, to disengage the cam from the fork camming surface, permitting the biasing spring to pivot the fork to its first position, wherein the wheel lies against the forward wall of the barrow body, crosswise of the longitudinal centerline of the barrow body.
