Claim:
1. A fixing structure of a separate leaf spring in a female type terminal fitting, the fixing structure comprising: a female terminal main body extending in an axial direction and including a fitting cylinder section press-molded in a square cylinder shape and into which a male type terminal can be inserted, the fitting cylinder section including a plurality of side wall plates forming the female main body into the square cylinder shape; and a leaf spring formed separately from the female terminal main body and fixed to the fitting cylinder section so that the male type terminal can be pressed by the leaf spring; wherein the fitting cylinder section includes a first side plate of the plurality of side wall plates from which a columnar body protrusion protrudes, the columnar body being monolithically formed with the first side plate; wherein the leaf spring includes a protrusion retaining section that has an insertion hole into which the columnar body protrusion can be inserted, and that is fixed to the first side plate by the protrusion retaining section that retains a top section of the columnar body protrusion inserted in the insertion hole; wherein the leaf spring further includes: a fixing plate connected to the protrusion retaining section; and a tongue-like piece which is folded from a tip edge of the fixing plate to extend towards the protrusion retaining section in the axial direction, wherein the fixing plate and the protrusion retaining section are in surface-contact with the first side plate of the fitting cylinder, wherein the leaf spring includes at least two fixing pieces which each protrude from sides of the fixing plate, and each protrude toward a respective one of a second side plate and a third side plate of the fitting cylinder section, each of the second side plate and the third side plate of the plurality of side wall plates being bent and molded at a side edge of the first side plate in a standing state, wherein each of the second side plate and the third side plate of the fitting cylinder section includes a spring fixing hole into which a fixing piece of the at least two fixing pieces is fitted into, wherein each fixing piece is shaped as a flat plate, and extends in a plane which is a same plane as an extending plane in which both of the protrusion retaining section and the fixing plate extend; and wherein the tip edge of the fixing plate from which the tongue-like piece is folded and an edge of the fixing plate to which the protrusion retaining section is connected are disposed opposite each other in the axial direction.
