Abstract
Improved attachment structure between a rotatable interdental device and a toothbrush handle having said device rotatable about a movable shaft. The device is held in position by positioners which engage when the device is at a predetermined angle to said handle and said shaft is in a first position. The positioners dissengage when the shaft moves to a second position. The positioners interact in a camming manner so that a predetermined force cams the shaft into its second position. The shaft extends from a resilient cantilever arm which biases the shaft toward the first position. The shaft also includes diverging wedgelike end surfaces which facilitate separating legs of the device for assembly of the shaft and device.
