Abstract
Disclosed is a connector for detachably and rotatably connecting one article to another article, which comprises an insert member to be attached to said one article and a receiving member having a space for insertion of said insert member, which is to be attached to said another member, wherein said insert member has an engaging annular peripheral portion having a void or hollow at the center thereof, a pair of spherical projections capable of elastic and reversional deformation are arranged in the insertion space of the receiving member to confront each other, and such a dimensional relation is established between the engaging annular peripheral portion and the spherical projections that the distance between apexes of the spherical projections is smaller than the thickness of the engaging annular peripheral portion and when said insert member is inserted into the receiving member, the engaging annular peripheral portion is rotatably gripped and supported by the peripheral parts of the paired spherical projections. This connector has a simple structure and is excellent in the stoutness and the adaptability to the operations of attaching two articles to each other and detaching them from each other. This connector is used especially suitably for detachably and rotatably connecting a mop handle and a mop supporting frame in a large-size floor cleaner.
