PROBLEM TO BE SOLVED: To provide an internal machine for Bourdon tube instrument without performance deterioration, capable of acquiring a noncontact signal for sequence control when reaching a set pressure value, and to provide a Bourdon tube instrument installed with the same. SOLUTION: The internal machine for Bourdon tube instrument indicates by expanding an amount of displacement of the tube tip 25 of the Bourdon tube 24, by transmitting a movement of one of the tube tips 25 of the Bourdon tube 24 having twin tube tips 25 via a sector gear 8 and a pinion shaft 3 to a measured value indicator needle 27, wherein the mechanism is provided such that a sensor mechanism 15, a light shielding plate 17, a boss mechanism 20 and a pedestal gear 22 are set and a setting indicator needle 23 is attached to a scale plate 26 and the pedestal gear 22 so that a setting gear 21 and a sensor mechanism rotating gear 16 are engaged and the setting gear 21 and the pedestal gear 22 are engaged.
