Abstract
A toothbrush having a handle and a rubber-like brushing structure having a plurality of brushing projections and mounted on the forward part of the handle is further provided with a rigid frame member surrounding the side surface of the brushing structure and engaged with the latter in a projection-and-recess relation, the frame member being bonded to the handle for indirectly securing the brushing structure to the handle, and the 'hardness' in operation of the toothbrush, i.e., the brushing projections, being adjusted by varying the height of the frame member measured perpendicularly to the lengthwise direction of the handle.
