PROBLEM TO BE SOLVED: To provide a grease supply structure of a leaf spring which can surely secure an approach angle of a grease supply device which supplies grease to the leaf spring.SOLUTION: An attachment 28 integrally has a first downstream-side opening end part which is connected to a nut 27, a first upstream-side opening end part, and a first grease supply path which penetrates a clearance between the first downstream-side opening end part and the first upstream-side opening end part while being bent in a substantially L-shape. A grease nipple 29 integrally has a second upstream-side opening end part which is connected to the first upstream-side opening end part, a gun connecting part 35 to which a grease gun 34 can be connected, and a second grease supply path which penetrates a clearance between the second upstream-side opening end part and the gun connecting part 35 while being bent in a substantially-L shape. Grease flowing into the second grease supply path of the grease nipple 29 from the grease gun 34 is supplied to an inside diameter part (grease supply hole) of the nut 27 via the first grease supply path of the attachment 28.SELECTED DRAWING: Figure 2

    【課題】リーフスプリングにグリスを供給する給脂装置のアプローチアングルを確実に確保することが可能なリーフスプリングのグリス供給構造の提供。【解決手段】アタッチメント28は、ナット27に接続される第1下流側開口端部と、第1上流側開口端部と、第1下流側開口端部と第1上流側開口端部との間を略L状に曲折して貫通する第1給脂路と、を一体的に有する。グリスニップル29は、第1上流側開口端部に接続される第2上流側開口端部と、グリスガン34が接続可能なガン接続部35と、第2上流側開口端部とガン接続部35との間を略L状に曲折して貫通する第2給脂路と、を一体的に有する。グリスガン34からグリスニップル29の第2給脂路に流入したグリスは、アタッチメント28の第1給脂路を介してナット27の内径部(グリス供給孔)に供給される。【選択図】図2
