In an assembled state of a hinge, the hinge is configured to be capable of adjusting a rotational position when holding a door or the like. The hinge includes a first member (1) and a second member (2) which are rotatable relative to each other. A first cam (11) is provided on the first member (1), a second cam (12) is provided on the second member (2) so as to be non-rotatable and movable in an axial direction thereof, and the second cam (12) is biased to the first cam (11) by biasing means (14) in the axial direction. The first cam (11) and the second cam (12) are configured to hold the second cam (12) in a predetermined rotational position relative to the first cam (11) by biasing force of the biasing means (14). In the assembled state of the hinge, it is possible to adjust the rotational position of the first cam (11) relative to the first member (1). The holding force of the first member (1) to the first cam (11) is larger than the holding force of the first cam (11) to the second cam (12) in a circumferential direction thereof.

A hinge device includes a fixed element with a plate that can be anchored to a stationary supporting structure, and a movable element with a hinge body that can be anchored to a closing element. Adjustment elements for the position of the hinge body and the plate include a pair of opposite longitudinal projections integrally joined to a pin that can be inserted into a slot defined in the plate. A pair of adjustment grub screws at the slot promotes the joined rotation of the longitudinal projections and the pin. The hinge body further includes a seat, for the mutual movement of the pin and of the hinge body, with a damping system interacting by friction with the pin to differentially dampen the rotation of the pin and the hinge body. The hinge device may be fixed to the closing element with a pair of clamping elements.

An engine cowling, comprising a housing part, at least one door element, and a hinge, wherein the hinge fixates the door element at the housing part in an openable and closable manner, wherein the hinge includes a first hinge element, a second hinge element and a bolt, and wherein the hinge includes an adjustment device that can be adjusted in such a manner that a relative position of the door element to the housing part can be altered.
