PROBLEM TO BE SOLVED: To provide a throttle valve opening/closing control device which can automatically restore a safety-control mechanical constitution to an initial state after a throttle valve has performed safety control so as to be brought into a full-closed state according to an increase of an operation amount of an accelerator pedal.SOLUTION: A throttle valve opening/closing control device 11 comprises: a first box body 33 having a slope part 37; a shaft 21 pivoted to the first box body 33; a knob 51 which is integrated with the shaft 21 coaxially therewith, and in which a step part 55 is formed; a guide 61 in which an engagement part 67 engaged with the step part 55 of the knob 51 is arranged, and which has an abutment part 69 abutting on the slope part 37 of the first box body 33, is turnable coaxially with the shaft 21, and interlocks with an accelerator pedal according to an operation amount of the accelerator pedal; a thrust spring 71 for energizing the guide 61 to the knob 51 in a direction of an axial line Z1 of the shaft 21; and a first torsion spring 41 which is interposed between the knob 51 and the first box body 33, and restores the shaft 21 to an original point.SELECTED DRAWING: Figure 2

    【課題】アクセルペダルの操作量の増加に応じてスロットル弁が全閉状態とする安全制御の作動後に、安全制御の機械的構成が初期状態に自動的に戻ることが可能なスロットル弁開閉制御装置を提供すること。【解決手段】スロットル弁開閉制御装置11は、勾配部37を有する第1筐体33と、第1筐体33に軸支されたシャフト21と、シャフト21に同軸で一体化されると共に段差部55が設けられたノブ51と、ノブ51の段差部55と係合する係合部67が設けられ、第1筐体33の勾配部37に当接する当接部69を有し、シャフト21に同軸で回動可能にされ、アクセルペダルの操作量に応じて連動するガイド61と、ガイド61をシャフト21の軸線Z1の方向でノブ51に付勢するスラストバネ71と、ノブ51と第1筐体33との間に介在し、シャフト21を原点復帰させる第1ねじりバネ41と、を備える。【選択図】図2
