WIPO Patent Application WO/2023/127547
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an interdental brush whereby pain to the gums is reduced and harm to the gums is reduced, while retaining high interdental insertability and a feeling of cleaning. An interdental brush (1) includes: a holding part (10) provided with a cylindrical guide section (12) on a tip side of a holding body (11); and a brush body (20) provided with a base shaft (22) on a rear end of a brush part (21). The base shaft (22) is accommodated in the guide part (12), and the brush part (21) is exposed from a tip of the guide part (12). An elastic member (30) is provided between the base shaft (22) of the guide part (12) and the holding body (11), and the elastic member (30) is elastically compressed in a long axis direction when a load directed toward the rear end is applied to the brush part (21) and, as a result, the brush part (21) retreats relative to the holding part (10) while being biased, in the long axis direction, toward the tip.
