Abstract
A toothbrush comprises two parts (2, 3) which are pivotable relative to one another, of which a first part (2) serves as a handle and of which a second part (3) carries a brush-head (5), a spring (7) being arranged between the parts and having one end (8) fixedly connected to one (2) of the parts and having another end (9) which engages with a wall portion (11) of the second part (3), the second part (3) being pivotable relative to the first part (2) against a pressure exerted by the spring (7) during use of the toothbrush, which spring snaps when a given pressure threshold (P.sub.d) is exceeded, after which the second part (3) is subjected only to a bending load in the absence of a pressure (Q) directed in the longitudinal direction of the spring (7) and exerted by the wall portion (11), and resumes its original position when the pressure has decreased.
