The present invention relates to a front cover of target frames of dartboards with a tidy appearance and a long service life, which comprises a cylindrical housing frame provided with a flange at the bottom edge used for connection. A metal gauze or spider is integrated with the cylindrical housing frame at the circumference. The toroidal and radial bars of the metal gauze are all provided with inverted V-shaped grooves, which are in the back of the metal gauze and filled with an injection molding filler to form a flat back surface.
