Abstract: A breather that allows airflow between an inside and an outside of a casing of an on-vehicle power unit or a transmission mechanism related to the power unit to be performed through a breather chamber structure includes a connecting portion and a cylindrical wall. An ATF-air mixture from the inside of the casing flows into the breather chamber structure through the connecting portion having a tubular shape. The cylindrical wall is provided in the breather chamber structure and has a cylindrical shape having one end portion that is closed and another end portion that is open. The ATF-air mixture from the connecting portion flows from an opening at the other end portion toward the one end portion through the cylindrical wall.

Abstract: A method for constructing a large-scale marine structure, which comprises: providing, near a dock (2) of which at least one end faces the waters through a gate (6), a pond (5) having an end thereof facing the waters through another gate (6'); constructing in the dock (2) a plurality of blocks (1A, 1B) for the large-scale marine structure (1); towing out the plurality of blocks (1A, 1B) thus constructed from the dock (2) to the waters, and towing same into the pond (5); tack-welding together the plurality of blocks (1A, 1B) in the floating state in the pond (5); discharging water in the pond (5) to cause the plurality of blocks (1A, 1B) thus tack-welded together to land onto the bottom (5a) of the pond (5); and fully welding together the plurality of blocks (1A, 1B) tack-welded together to construct the large-scale marine structure (1).
