Catapult for launching miniature vehicles, which is characterized by comprising a flat support with the appropriate profile at its base to be coupled at the starting point or another intermediate of the track, presenting in its upper part two partitions perpendicular to the base and parallel to each other, through which a plunger with a tubular structure slides, provided with a front elastic pad and a longer central back rod, topped by a handle with elastic lining, which abuts against the rear partition, involving the traction of said handle the load of the coil spring included in the interior of the piston, said spring compressing between the bottom of the piston and the rear partition of the general support, and determining its release, upon release of the handle, the launching of the vehicle, previously supported by simple gravity against the anterior elastic plug of the piston.
