For projectiles of, for example, anti-aircraft guns, nose-impact fuzes are known which contain a melting part (11) which melts after firing and allows an impact spindle (12) to move forwards. However, after this has been done, even raindrops which strike the impact spindle can lead to premature explosion of the projectile. The object of the invention is to construct and arrange rain-protecting parts, which move into the space previously occupied by the melting part (11) before it melted, such that said rain-protecting parts prevent the transmission of small shocks through the impact spindle (12) to an impact bolt. For this purpose, the rain-protecting parts (13, 14) are arranged in an annular groove of the impact spindle (12) or are guided in holes in the impact spindle such that, together with a projection (16) which is located in the hole for the impact spindle (12), they form an interlock which prevents the transmission of a shock caused by raindrops via the impact spindle (12) to the impact bolt. <IMAGE>
