The nucleon-meson vertex structure is discussed by using the transition potential of one-gluon exchange with the production of a quark-antiquark pair, which is deduced from quark-gluon interaction, based on the nonrelativistic quark model. The transition probabilities for nucleon..-->..nucleon+meson, obtained by generator-coordinate method, show that the mesons exchanged in the nucleon-nucleon interaction are produced mainly in the surface region of a nucleon. However, there also exist some probabilities of finding mesons inside a nucleon. The fact that the relative probability of ..pi.. meson is largest in the long-range interaction shows its importance in the processes of meson exchange. The effect of meson size on probabilities, which shows the coupling strength of meson and nucleon, is also discussed.
