PROBLEM TO BE SOLVED: To provide a helicopter in which a transmission is correctly operated for a predetermined time even when a lubricating circuit is damaged. SOLUTION: A helicopter 1 comprises a first member 7 movable with respect to a second member 8; lubricated supporting means 9 for supporting the first member with respect to the second member; and a primary lubricating circuit 20 for lubricating the supporting means 9 and in turn having primary storage means 11 for accumulating a lubricating fluid, and primary fluid feed means 12 for feeding the lubricating fluid to the supporting means. The helicopter 1 further comprises an auxiliary lubricating circuit 22 supplying the lubricating fluid continually from the primary storage means at a first lubricating fluid flow rate, and continually supplying the fluid to the supporting means at a second lubricating fluid flow rate lower than the first rate, so as to produce an auxiliary reservoir 23 of lubricating fluid for use in the event of breakdown of the primary lubricating circuit.
