PROBLEM TO BE SOLVED: To prevent a vehicle theft by replacing an anti-theft device with another device. ! SOLUTION: A vehicular anti-theft device 20 includes: a storage processing section 35 which makes a storage section 36 store a position of an in-cylinder piston position during the stop of an engine 10 which is detected by a piston position detecting section 33 when the driving of the engine 10 is stopped; a piston position comparing section 34 which determines whether a position of the in-cylinder piston when starting the engine detected by the piston position detecting section 33 coincides with a position of the in-cylinder piston during the stop of the engine stored in the storage section 36 when an operation detecting section 32 detects the operation starting the engine 10; and an engine driving control section 37 which prohibits fuel injection by a fuel injector 14 when the piston position comparing section 34 determines that a piston of the in-cylinder piston when the engine is started coincides |
