摘要

A friction stay comprising a vent arm (24) moveable relative to a fixed component (10) fixed, in use, to a stationary part of a window frame, the vent arm (24) and the fixed component (10) each having projections (32, 38) associated therewith co-operable with one another when the vent arm (24) occupies a closed position to inhibit movement of the vent arm (24) in the longitudinal direction thereof. The vent arm (24) further carries a projection (44) co-operable with a stop (46) when the vent arm (24) occupies its closed position, the projection (44) being out of alignment with the fixed component (10) when the vent arm (24) occupies this position.
