PURPOSE: Automatic injector for injection is provided which uses pressure from chemical reaction between two reactive materials to advance a piston for discharging injection so that it shots the amount to be injected exactly. CONSTITUTION: The automatic injector for injection comprises the parts of: a cylinder(10) which includes a discharging hole(14) to discharge injection little by little at the front side; a piston(20) which is airtightly placed in the cylinder to discharge injection in the cylinder into the discharging hole; a capsule receiver(30) which is bound with the rear side of the piston with including multiple capsule grooves(32a)(32b); a working lever which includes capsule insertion grooves(42a)(42b) at the front side; and multiple capsules(46a)(46b) which is inserted to the capsule receiver and the capsule groove with including chemicals that are mixed to generate gas.
