PROBLEM TO BE SOLVED: To provide a bulletin board capable of stably sliding and supporting a bulletin object. SOLUTION: The V-opening type bulletin board is connected with a transparent plate to a substrate at the bottom end V-openably to incline forward in order to hold the bulletin object in-between. Either of the substrate or the transparent plate is projected with a slide receiving section for the bulletin object. Also, the bulletin board is equipped with an opening/closing holding device to stop the transparent plate to either opening or closing at the top end. The opening/closing holding device is projected with a slide pin 27 having an engaging recessed groove 41 on the back of the transparent plate 3. The substrate 1 is equipped with a slide hole 55 penetrated with the slide pin, a spring means 28 compressed and interposed between the substrate and the transparent plate by being inserted to the slide pin, and a locking unit 32 partly dropped by elastic force and locked into the engaging recessed groove in closing of the transparent plate accompanied by the further compression of the spring means. The substrate is provided with a stopper for setting the opening angle when the transparent plate is opened by the elastic force of the spring means accompanying unlocking.
