A USB(Universal Serial Bus)-type DMB(Digital Multimedia Broadcasting) receiver is provided to safely protect a tip part by reliably maintaining the rotation state of a cover part and to prevent the loss of the cover part by forming the cover part so as not to be separated from a main body. A USB-type DMB receiver(100), which consists of a main body(110), a C-shaped rotating cover part(120), a DMB receiving circuit, a tip part(111) and an antenna(113), comprises the first coupling part and the second coupling part. The first coupling part, sunflower-shaped, is comprised of a circular recess, a pleated recess, and a C-shaped guide slot. The circular recess is concavely formed at the case(112) of the main body(110). The pleated recess, smaller than the diameter of the circular recess, is more concaved at the center of the bottom of the circular recess. At the pleated recess, curved uneven portions are periodically formed along the circumference. The C-shaped guide slot is formed at the bottom surface of the edge of the circular recess. The second coupling part, pivot-type, is formed at the inner surface of a lateral end of the cover part(120) so as to be correspondingly combined with the first coupling part.
