    (54) Mechanism for a munition device


    (57) Mechanism for a muniton device. The mechanism includes a housing (1) containing an arming element (3) and a spindle (9) capable of giving the arming element an axial movement. The spindle (9) is operatively connected to the arming element (3) via a conveyor means (10) which has a thread profile (12), the conveyor means being pivotally journalled in the arming element such that it is able to be turned between a first position (Figures 1 and 2), wherein the thread profile (12) is in engagement with the spindle (9), to a second position (Figures 4 and 7) wherein the thread profile (12) of the conveyor means is disengaged from the spindle. Spring means (4, 13), are arranged, in the armed position of the conveyor means, to return the arming element to said engagement with the movable member.
