ABSTRACT:
The description relates to a closure for mounting in an opening in a thin wall, such as a sheet metal cabinet door, which comprises a housing and which has, at one end, a bearing support for an actuation lever and, at its other end, a lock device for the actuation lever and a fastening device such as a clamping clip therebetween. The housing has a partially spherical bearing surface with a cylindrical bore hole proceeding from it, wherein a partial ball with a first bearing for a closure drive shaft extending through the cylindrical bore hole and with a second bearing for the actuation lever is arranged in the cylindrical bore hole, and the two bearings enable a rotation of the partial ball in relation to the housing and a swiveling of the actuation lever in relation to the partial ball around an axis vertical to the closure drive shaft and to the extension of the lever.
