Abstract
Abstract A wheeled toy truck body is shown having a spring operated boom mounted therein, the boom holding a toy vehicle engaging member such as a hook. The boom is forced downwardly to lower the hook and engage and hold a portion of a toy vehicle to be towed and upon being released, the boom returns to its unflexed position to thereby raise the hook and lift the toy vehicle. The hook may be a separate member or it may be an integral part of the boom.
