Abstract
Abstract A passenger body roof opening and detachable tiltable cover is provided. To accommodate tilting movement of the cover, a telescoping device is provided at the rear end thereof which is detachable attachable to the cover. The telescopic device includes a first threaded portion fixed to a body frame at the opening, a second threaded portion detachable connected directly to the cover, and at least one further threaded portion threadably engaging with the first and second threaded portions. To accommodate retraction of the telescopic jack when the cover member is detached from the second threaded portion, the second threaded portion is non-rotatably connected to the frame by way of a rectangular sleeve arrangement which permits telescoping axial movement of the threaded member, while preventing rotative movement.
