Abstract
(EN)
Provided is a stud that is improved so as to increase resistance to torque, thereby preventing loosening from sheet metal to which same is press-fitted. The stud comprises: a body part which is inserted into a stud mounting hole formed at the sheet metal, and in which threads to which a screw is fastened are formed; a flange part which is provided at one side of the body part to have a diameter larger than that of the stud mounting hole, and which is press-fitted into the sheet metal; and a rotation-preventing part which protrudes from the flange part to have a diameter larger than that of the stud mounting hole and smaller than that of the flange part, and which is press-fitted to the sheet metal so as to prevent the rotation of the stud, wherein the rotation-preventing part includes a plurality of rotation-preventing protrusions having an asymmetrical shape, and the plurality of rotation-preventing protrusions include rotation-preventing surfaces that are perpendicular to the tangential line of a circle connecting the ends of the plurality of rotation-preventing protrusions.

L'invention concerne un goujon qui est amélioré de façon à augmenter la résistance au couple, empêchant ainsi le desserrage de la tôle auquel il est emmanché. Le goujon comprend : une partie corps qui est insérée dans un trou de montage de goujon formé dans la tôle, et dans laquelle des fils auxquels une vis est fixée sont formés; une partie de bride qui est disposée sur un côté de la partie corps pour avoir un diamètre plus grand que celui du trou de montage de goujon, et qui est ajustée par pression dans la tôle et une partie empêchant la rotation qui fait saillie à partir de la partie de bride pour avoir un diamètre plus grand que celui du trou de montage de goujon et inférieure à celle de la partie de bride, et qui est ajustée par pression sur la tôle de façon à empêcher la rotation du goujon, la partie empêchant la rotation comprenant une pluralité de saillies empêchant la rotation ayant une forme asymétrique, et la pluralité de saillies empêchant la rotation comprend des surfaces empêchant larotation qui sont perpendiculaires à la ligne tangentielle d'un cercle reliant les extrémités de la pluralité de saillies empêchant la rotation.
