The present invention relates to a chain stopper with a locking pawl opening and closing structure, comprising a roller, locking pawl, through-hole, first shaft, pair of fixing members, first gear, second gear, second shaft and handle member. The locking pawl is rotatably installed between a pair of external walls. The locking pawl covers the roller. The through-hole is formed on one side of the locking pawl. The first shaft passes through the through-hole to be inserted and be installed and forms a rotation point of the locking pawl. The fixing members are installed on the first shaft and fixe the first shaft to the locking pawl. The first gear has a fan-shape and is installed on the front end of the first shaft. The second gear is engaged with the first gear. The second shaft is installed on the second gear. The handle member is installed on the front end of the second shaft. According to the present invention, the locking pawl with a heavy weight can easily be opened and closed by transferring rotational force of the handle by meshing of the gear to the locking pawl such that the locking pawl can rapidly and easily be opened and closed by human power.
