Abstract
A shift lock system for an automatic transmission is arranged to make it unfeasible to cancel the shift lock without a tool. The shift lock system includes a cancel lever for moving a shift lock member such as a rotary bush from a lock position for locking a shift lever in the park position to an unlock position against the force of a return spring, a cancel rod for operating the cancel lever, and a plug member which is normally fastened with the cancel rod to a support member by a screw fastener so that the cancel rod is immovable. The plug member can be loosened by a tool such as a screw driver. When loosened, the plug member allows a canceling operation by allowing the cancel rod to be moved.
