FIELD: automotive industry. ^ SUBSTANCE: invention relates to fasteners used for connecting thin-walled parts in automotive industry. Proposed fastener has support part 1, attachment devices 2 and fixing member 3 consisting of four elastic lobes 7 with outer meeting sides 8, inner surfaces 9 pointed inwards the space limited by lobes, and side surfaces 10, 11. Each lobe is connected by one end to plate support part and is connected by other end to the rest of lobes, thus forming end face 12. Lobes are provided with mounting cavities 14 and are arranged on support part uniformly relative to axis of fastener. AT least one pair of lobes installed opposite to each other relative to axis 13 of member is located at different sides of plane containing the axis. Side surfaces of indicated pair of lobes are parallel to each other and to indicated plane. Inner surface of each lobe is pointed to gap between its adjacent and opposite lobes. Each lobe is made with decrease of size from one side surface to the other in plane of section perpendicular to axis. ^ EFFECT: improved reliability of fastener. ^ 4 cl, 5 dwg |
