Abstract

La présente invention concerne une flèche (17) pourvue d'un corps (30) et d'un support d'extrémité proximale (31). Le corps (30) comprend une section droite (30a) et une section large (30b). La section droite (30a) a une largeur sensiblement constante (Wa) lorsqu'elle est vue de dessus. La section large (30b) a une largeur (Wb) qui s'élargit en s'approchant du support d'extrémité distale (31) lorsqu'elle est vue de dessus. La section droite (30a) et la section large (30b) sont continues de manière régulière.
