To provide a device for cleaning a sandy beach, by collecting refuse thrown away on the sandy beach and refuse buried in sand.

In this sandy beach cleaning device, a plurality of support bars 3 are equally arranged in the circumferential direction of support plates 2 between a pair of right and left support plates 2 to be installed and fixed; a cylindrical drum 5 capable of rotating and traveling on the sand is formed by connecting an intermediate part of the support bars 3 by a plurality of reinforcing materials 4, a plurality of refuse collecting arms 6 are projected in the outward direction of the drum 5 on the respective support bars 3, a cover body 8 capable of regulating an opening angle is rockably arranged in the drum 5, and an input port 7 between the respective support bars 3 can be opened and closed by the cover body 8. The support plates 2 are formed in polygonal shapes. The arms 6 projected on the support bars 3 are formed by bending or curving the tip in the rotational direction of the drum 5 by extending in a straight line shape in the radial direction of the support plates 2, or by forming the tip in an expansive opening bifurcated shape by extending in a straight line shape in the radial direction of the support plates 2.
