PROBLEM TO BE SOLVED: To store fallen leaves, etc., having accumulated on a stagnant space into a dustpan without using a broomstick, depending on natural laws. SOLUTION: The dustpan is shaped like a sector, and an angle thereof is set to 90 degrees. Further, side surfaces of the dustpan are perpendicularly erected to a bottom surface of the same. Thus, the dustpan can be set at a wall corner which can be the stagnant space, without forming a gap.
