1. A slider for a slide fastener, wherein the slider comprises: a slider body for coupling and releasing tooth rows of a fastener chain; a pull holding body which is supported and fixed on an upper portion of the slider body and holds a pull movably between the pull holding body and the upper surface of the slider body; a spring body having a spring piece to be elastically disposed between the pull and a rear surface of the pull holding body while being made of a platy material having an opening window portion at one end side thereof and a pawl portion at a front end of the other end side thereof; and first and second post portions on back and forth on the upper surface of the slider body; wherein the slider has support walls that are built at right and left side edges of the first and second post portions and at least front and rear end portions of the pull holding body are fit and supported therein, and an end portion at a side of the pawl portion of the spring body and an end portion at an opposite side thereof are fit between the right and left support walls which are respectively disposed on back and forth on the upper surface of the slider body; the pull holding body is composed of a substantially lateral C-shaped cover body, the substantially lateral C-shaped cover body having front and rear wall portions that are formed back and forth of an upper wall portion and being connected together only by the upper wall portion; and inner surfaces at the front end portions of the front and rear wall portions have engaging pieces to be elastically engaged with locked portions that are formed in the first and second post portions; the spring piece, which is cut out, bent and pulled up at a predetermined height in such a manner that a longitudinal center portion of the platy material is cut out outward from an end portion of the opening window portion; the pawl portion of the spring body is engaged with and released from a portion of the tooth rows of the fastener chain through an inside of the slider body on the basis of an elastic deformation of the spring piece by operating the pull; and outer surfaces of the support walls of the first and second post portions are completely exposed when the C-shaped cover body is engaged with the first and second post portions.
