Abstract:
The objective of the present invention is to provide a replaceable-head-type toothbrush in which operability and ease of removability of a replacement head can be improved. The present invention is a replaceable-head-type toothbrush in which a body and a replacement head part that has a brush part and is positioned at the side of the main part on the long-axis-direction tip are detachable, wherein the body has a gripping part and a shaft part that extends from the gripping part toward the long-axis-direction tip end. The replacement head has: a head body having the brush part; a leaf spring part that extends from the head body toward the long-axis-direction rear end, and engages with the shaft part due to elastic force on one side facing the shaft part in a radial direction that intersects the long-axis direction; and a detachment assistance part that is connected to the leaf spring part, and deforms the leaf spring part toward the other radial-direction side when external force is applied.
