ABSTRACT:
A rotary eraser has a simple structure, is extremely capable of erasing a letter or other printed material, and facilitates an adjustment of the position of the erase. The rotary eraser includes a cylindrical body, an eraser holder which holds a rod eraser and is rotated by pressing down the body, an outer cylinder which is rotatable together with the eraser holder, an energizing component which biases the eraser holder in a direction in which the rod eraser protrudes, and an eraser bearer by which the position of the eraser in the eraser holder can be changed when the outer cylinder is turned.
