1. A core for an armrest, the core being for an armrest that is supported rotatably onto a seat in a cantilevered manner, and the core comprising: a framed body being made of resin and having a bottom; a stopper pin being made of metal, the stopper pin being subjected to insert molding in said framed body so as to protrude a leading-end shaft thereof toward an outer side of said framed body, and being hooked onto a stopper of said seat, thereby being restricted from rotating; and a rib being integrally molded onto said framed body inside the framed body, said rib being raised from said bottom in an axial direction of said stopper pin; and wherein said stopper pin has a base-end large-sized section with a base-end side thereof and an opposite side face to said base-end side, the base-end large-sized section being formed as a cross-sectional configuration that is larger than that of the leading-end side, the leading end shaft extending from the base end side; said rib being disposed so as to overlap with respect to a base-end face of said base-end large-sized section of said stopper pin in an axial direction of said stopper pin, wherein the base end large-sized section is sandwiched between the bottom of the framed body and a portion of the rib.
