ATTACHMENT COMPONENT AND LIGHT SOURCE UNIT

PROBLEM TO BE SOLVED: To provide an attachment component capable of fixing a fixation component such as a light source unit to a fixed component without using a screw, and a light source fixed to the fixed component without using a screw.SOLUTION: A waterproof bushing 37 as an attachment component includes: a first projection part 52A penetrating a pore 12X provided in a support pillar 12 as a fixed component, and locked to the rear side of the pore 12X; and a second projection part 52B projecting in the same direction as the first projection part 52A around the first projection part 52A, and contacting with the front side of the pore 12X in penetrating the first projection part 52A through the pore 12X. Also, in a state where the second projection part 52B contacts with the front side of the pore 12X, the first projection part 52A is pushed toward the pore 12X and the waterproof bushing 37 elastically deforms, and thereby the first projection part 52A is locked to the rear side of the pore 12X, and a light source unit 31 is fixed to the support pillar 12 with resilience of the waterproof bushing 37.SELECTED DRAWING: Figure 8 【課題】ねじを用いずに光源ユニット等の固定部品を被固定部品に固定可能にした取付部品、及び、ねじを用いずに被固定部品に固定される光源ユニットを提供すること。【解決手段】取付部品である防水ブッシング３７が、被固定部品である支柱１２に設けられた孔部１２Ｘを貫通して孔部１２Ｘの裏側に係止する第１突起部５２Ａと、第１突起部５２Ａの周囲にて第１突起部５２Ａと同方向に突出し、第１突起部５２Ａを孔部１２Ｘに貫通させた際に孔部１２Ｘの表側に当接する第２突起部５２Ｂとを備える。また、第２突起部５２Ｂが孔部１２Ｘの表側に当接した状態で、第１突起部５２Ａが孔部１２Ｘに向けて押し込まれて当該防水ブッシング３７が弾性変形することで第１突起部５２Ａが孔部１２Ｘの裏側に係止し、当該防水ブッシング３７の復元力で光源ユニット３１を支柱１２に固定するようにした。【選択図】図８
