PROBLEM TO BE SOLVED: To directly attach front winkers to respective side surfaces of a front cowl without increasing thickness or providing reinforcement of metal plates, and to increase a flow straightening surface in rear of the front winkers.SOLUTION: Winker attachment bosses 35 are integrally formed on a cowl body 30 constituting a front cowl 15 by protruding part of side surfaces of the cowl body 30 outward and cylindrically, respectively, hexagonal nuts 38 are contained in the respective winker attachment bosses 35, and stud bolts 39 provided on tip ends of support arm portions 37 of the front winkers 17 are fastened to the hexagonal nuts 38, respectively. A protruding shape of each winker attachment boss 35 can increase the rigidity of each side surface of the cowl body 30 and makes it unnecessary to increase thickness and to provide reinforcement of a metal plate. A protruding height of each winker attachment boss 35 is generally equal to a height of each hexagonal nut 38, an inside diameter thereof is equal to or larger than an outside diameter of the hexagonal nut 38, and the entire hexagonal nut 38 is contained in the winker attachment boss 35 and not protruded inward of the front cowl 15.
【課題】フロントカウルの側面へ肉厚増大や金属板の補強をせずに、フロントウインカを直接取付けてフロントウインカ後方における整流面を大きくする。【解決手段】フロントカウルを構成するカウル本体部30の側面の一部を筒状に外方へ突出させてウインカ取付ボス35を一体に形成し、このウインカ取付ボス35内に六角ナット38を収容し、フロントウインカ17の支持腕部37先端に設けられた植込ボルト39を締結する。ウインカ取付ボス35の突出形状により、カウル本体部30の側面における剛性が高くなり、肉厚増や金属板の補強を不要にする。ウインカ取付ボス35は突出高さが六角ナット38の高さと同程度、内径が六角ナット38の外径と同等以上であり、六角ナット38全体をウインカ取付ボス35へ収容し、フロントカウル15の内側へ突出させない。【選択図】 図6
