PURPOSE: To provide an air gun for rivets capable of minimizing strain applied to a matrix, uniformizing shape of rivets clamped, easily clamping solid rivers utilizing a tool used when clamping conventional blind rivets and selectively clamping blind type rivets and solid type rivets using a tool. CONSTITUTION: An air gun for rivets comprises an air cylinder(130); a lever(120) for supplying air into the air cylinder or cuts off air supplied into the air cylinder; a moving member(180) which is connected to an one end part of piston(140) of the air cylinder, and on a central part of which a groove(182) is formed; a fixing member(150) which is connected to a body part of the air cylinder, into which the moving member is inserted, and on which a cutout part(154) is formed such that the groove is exposed to the outside; a forming plate which is fixed to an inner wall at one side of the groove of the moving member, and on which a semispherical forming groove(196) is formed; and a river supporting plate which is fixed to an inner wall at one side of the cutout part of the fixing member, and on which a semispherical supporting groove(166) is formed, wherein the forming plate comprises a support(190), and a replacement element(194) which is inserted into the support, and on which the forming groove is formed, and wherein the river supporting plate comprises a support(160), and a replacement element(164) which is inserted into the support, and on which the supporting groove is formed.
