(54)	Improvements relating to closure members

(57) A drive transfer and locking mechanism for a closure member (15), said mechanism comprising a first arm (12) to be moved arcuately by drive means (11) for effecting pivotal opening and closing of an aperture by the closure member (15), and a second arm (14) to support the closure member (15). Detent means (20) are provided to interengage and interconnect the first and second arms (12,14), the detent means (20) being resiliently operable in a generally vertical direction under the inherent resiliency of at least the first arm (12). The mechanism additionally includes magnetic means (25) to provide a magnetic attractive force between magnetically permeable regions of the two arms (12,14) to aid the detent means (20) in holding said interengaged and interconnected condition of the first and second arms (12,14).
