An article box for a beach buggy is positioned under the rear end of the saddle of a beach buggy. The frame body of the beach buggy is partitioned and formed with an uncovered accommodating space, and the article box with its opening facing upward is embedded in the accommodating space and concealed under the saddle of the beach buggy. By so designing, after the saddle of the beach buggy is pulled open, the driver can put his safety helmet or other things into the article box, convenient in use.
