An exhaust apparatus for fluorescent lamps has a transferring conveyor which intermittently conveys several carriers. Each of the carriers has several support heads to support bulbs which are connected through exhaust tubes to first connecting pipe members. Working heads are successively located at predetermined positions along the conveyor. Each of the working heads has second connecting pipe members which are detachably connected to the first connecting pipe members, respectively. Further, first and second valves are attached to the first and second connecting pipe members to open and close inner passages in the first and second connecting pipe members.
