A plate fastener made of a synthetic resin for fastening together two plates in a face-to-face relation comprises a head portion to be locked in an engagement hole formed on one of the two plates, a cylindrical leg portion perpendicularly extending from the bottom of the head portion and to be locked in a mounting hole formed in the other one of the plates, and an umbrella-like elastic engagement portion extending from the outer periphery of a stem portion of the leg portion and to be in close area contact with the other plate, the leg portion having a projection formed on the outer periphery to engage with the edge of a mounting hole formed in the other plate in a face-to-face relation to the engagement portion and a reduced-thickness axial hinge portion formed in the wall portion other than the projection, the wall of the leg portion being flexed in the folding fashion about the hinge portion. |
