A toothbrush handle part of an electric toothbrush has a handle part neck connectable to an attachment, at least one drive element for driving the attachment, said drive element being supported movably relative to said handle part neck, and a retarding element for retarding and/or locking and/or blocking and/or slowing down the drive element. The retarding element is movable relative to said drive element from a retarding position preventing movement of said drive element to an unretarding position allowing free movement of said drive element. The retarding element is accommodated between the handle part neck and the drive element to be slidable along said drive element in the longitudinal direction thereof from said retarding position in which said retarding element is in engagement with both the drive element and the handle part neck, to said unretarding position in which the retarding element is in engagement with not more than one of the drive element and the handle part neck.
