This invention relates to a steering control device of an endoscope, comprising a base plate, a lower cover fixedly disposed on the lower surface of the base plate, a spindle having a disk body and a rod body, a gasket, and a lower rotary disk, a spacing member, and a upper rotary disk respectively having a disk body, a column body, and a through hole. The disk body of the spindle is disposed between the lower cover and the base plate and fixed to the lower cover. The disk body of the lower rotary disk is stacked on the disk body of the spindle. The gasket is disposed between the disk body of the lower rotary disk and the base plate. The rod body of the spindle and the column body of the lower rotary disk penetrate through the base plate and the rod body of the spindle is disposed to the through hole of the lower rotary disk. The disk body of the spacing member is fixed on the upper surface of the base plate. The disk body of the upper rotary disk is stacked on the disk body of the spacing member. The column body of the lower rotary disk is disposed to the through hole of the spacing member. The column body of the spacing member is disposed to the through hole of the upper rotary body. Accordingly, the steering control device has a stable structure and smooth and accurate operation.一種內視鏡之轉向操控裝置,包含有一基板、一固設於基板下表面之下蓋、一具有盤體及桿體之心軸、一墊片,以及分別具有盤體、柱體及穿孔之一下轉盤、一分隔件及一上轉盤,心軸之盤體設於下蓋與基板之間並固定於下蓋,下轉盤之盤體疊在心軸之盤體上,墊片設於下轉盤之盤體與基板之間,心軸之桿體及下轉盤之柱體穿過基板,且心軸之桿體設於下轉盤之通孔,分隔件之盤體固定於基板上表面,上轉盤之盤體疊在分隔件之盤體上,下轉盤之柱體設於分隔件之通孔,分隔件之柱體設於上轉盤之通孔;藉此,該轉向操控裝置結構穩固、運作順暢且準確。10‧‧‧轉向操控裝置11‧‧‧基板111‧‧‧上表面112‧‧‧下表面12‧‧‧上蓋121‧‧‧板體122‧‧‧側周壁123‧‧‧固定板125‧‧‧通道126‧‧‧柱體127‧‧‧通孔13‧‧‧下蓋14‧‧‧心軸142‧‧‧桿體15‧‧‧下轉盤152‧‧‧柱體153‧‧‧通孔17‧‧‧分隔件18‧‧‧上轉盤182‧‧‧柱體183‧‧‧通孔20‧‧‧繩索30‧‧‧鏡頭
