Abstract: A cam lock that includes a cam body having a lobe-shaped working periphery and rotatable between a first locking position and a second unlocked position, a handle shaft mounted to the cam body for moving the cam body through a predetermined range of motion, and a cam shaft mounted to the cam body for pivotal movement relative to the cam body and having an end remote from the cam body for being fixed to a structure to be locked by a force applied against the structure. A bushing is mounted on the cam shaft and has an end proximate the cam body against which a locking force is applied when the cam body is rotated into its locking position.
