A push rivet is molded in a shape to be difficult for a foreign material to enter into an inside when an attached member is fixed, and includes a rivet main body and a pin. The rivet main body includes at least a flange portion having an insertion hole, a connected leg portion in which a pair of legs projecting toward an end side from the flange portion is mutually connected in the end side, protection pieces provided to protrude toward a space between a pair of legs from a pair of legs in the connected leg portion to protect the foreign material from entering, at least a pair of split leg portions projecting toward the end side from the flange portion to form slits between the split leg portions and the connected leg portion, and bulging-out portions projecting toward an inside direction of the connected leg portion and the split leg portions, and having tapered surfaces inclining inward as the tapered surfaces head for ends. The pin includes at least a head portion fitted into the flange portion, a shaft portion projecting toward the end side from the head portion, and which is provided with cavities on an inside, corner portions provided at side surfaces of the shaft portion, and slidably fitting into the slits, and concave grooves enlarging a diameter of the connected leg portion by engaging with the bulging-out portions of the respective leg portions.
