A vacuum cleaner comprises a closure (12) having a first hinge portion (13) and body (10) having a second hinge portion (15) displaceably mounted thereon, the first portion (13) is pivotally connected to the second portion (15) for rotation of the closure (12) about a rotational axis (A-A) relative to the body (10). The vacuum cleaner further comprises an axially projecting cam (17) on the first portion (13) having a cam surface disposed radially outwardly of the rotational axis (A-A), and a fixed abutment surface (18) disposed remote from the hinge portions (13,15). The surface of the cam (17) is biased against the abutment surface (18) by a spring (16) acting on the second hinge portion (15), the cleaner being arranged such that rotation of the first hinge portion (13) about the rotational axis (A-A) causes the cam (17) to ride over the abutment surface (18) under the applied bias allowing upward translatory movement of the rotational axis (A-A) of the closure. |
