1. A writing implement comprising:
a tubular body having a barrel;
a clip;
a pillar formed on an outer surface of the tubular body;
a connecting structure connecting the clip and the pillar;
a compressed coil spring extended between an inner surface of the clip and the tubular body, the compressed coil spring being capable of loading the clip such that a front end part of the inner surface of the clip is pressed elastically against the outer surface of the tubular body and of permitting the clip to be turned on the connecting structure so that the front end part of the inner surface of the clip is separated from the barrel when a back end part of the clip is pressed toward the tubular body; and
a projection formed on the outer surface of the tubular body at a position behind the pillar so as to project from the outer surface of the tubular body toward the clip and to support the compressed coil spring thereon,
wherein the clip is provided with a back wall inside a back part thereof, and the compressed coil spring is disposed on a front side of the back wall.
