MANUFACTURING METHOD OF THROTTLE DEVICE

To promote the size reduction of a product, and to simplify the positioning work of a full-closed stopper or the like.SOLUTION: A manufacturing method of a throttle device has: a throttle body 10; a throttle valve; a throttle gear 30; a spring member 40; a full-closed stopper mechanism composed of a body-side full-closed abutment face 115f at the throttle body 10 side and a gear-side full-closed abutment face 37m at the throttle gear 30 side; an abutment face of an initial opening regulation part 47 which is arranged at the spring member 40 integrally therewith; and an initial opening stopper mechanism composed of the initial opening regulation stopper abutment face 115f at the throttle body 10 side. At least one point of the body-side full-closed abutment face 115f, the gear-side full-closed abutment face 37m, an abutment face 47f of the initial opening regulation part 47, the initial opening regulation stopper abutment face 115f, an initial opening regulation part abutment part 38k, and an engagement part 47k of the initial opening regulation part 47 so as to bring about a positional relationship in which a full-closed position and an initial opening position relatively form a prescribed angle.SELECTED DRAWING: Figure 7 【課題】製品の小型化を図るとともに、全閉ストッパ等の位置調整作業を簡素化する。【解決手段】スロットルボディ１０と、スロットルバルブと、スロットルギヤ３０と、バネ部材４０と、スロットルボディ１０側のボディ側全閉当接面１１５ｆとスロットルギヤ３０側のギヤ側全閉当接面３７ｍとからなる全閉ストッパ機構と、バネ部材４０と一体的に設けられた初期開度規制部４７の当接面と、スロットルボディ１０側の初期開度規制ストッパ当接面１１５ｆからなる初期開度ストッパ機構とを有するスロットル装置の製造方法であって、全閉位置と初期開度位置とが相対的に所定角度を形成した位置関係となるように、ボディ側全閉当接面１１５ｆ、ギヤ側全閉当接面３７ｍ、初期開度規制部４７の当接面４７ｆ、初期開度規制ストッパ当接面１１５ｆ、初期開度規制部用当接部３８ｋ、及び初期開度規制部４７の係合部４７ｋの少なくとも一か所を加工する。【選択図】図７
