Abstract: A nose fairing (10) is a nose fairing coupled to a main body (12) of a rocket (11) so as to be separable from the main body. The nose fairing includes: a pair of fairing pieces (40, 50) that are separated after a predetermined time has elapsed since the rocket is launched, the pair of fairing pieces being engaged with each other and maintained in a coupled state before the pair of fairing pieces separate; a biasing structure (60) that biases the fairing pieces in a proceeding direction of the rocket to separate the fairing pieces from the main body; and a separating mechanism (13) that releases the engagement between the pair of fairing pieces and separates the pair of fairing pieces in such a manner that a distance of separation of one of the pair of fairing pieces from the main body is made longer than a distance of separation of the other of the pair of fairing pieces from the main body.

Abstract: A separation device includes: an outer case; a pillar-shaped separation member including an engaging portion; a support member including a swinging portion and an engageable portion, the swinging portion being swingably supported by the outer case, the engageable portion supporting the separation member; an inner case including a fitting hole restricting swinging of the support member; and an operation-enabling element, which supports the inner case and which is fusion-cut when an electric current is applied thereto. When the operation-enabling element is fusion-cut, the inner case is displaced, such that: the engageable portion of the support member detaches from the fitting hole; the swinging portion swings; and the engageable portion moves away from the engaging portion to release the separation member.
