Abstract A toy tow truck having a hoist boom pivoted at its forward end to the truck body for raising and lowering movement with a tow bar suspended from the rear end of the boom and an upright lever having its lower end pivoted to the body and having an intermediate portion engaging a slot in the boom to raise and lower the boom as the lever is swung in fore and aft directions. The boom is locked into position by the lever which seats in its pivot sockets under internal spring tension eliminating the need for rivets or pivot pins to mount either component.
