To enable even a physically weak operator to easily perform supply operation, in a pressure gauge with a filling function that moves a valve to an open position by manual operation against elastic force energizing to a closed position and supplies compressed air to a tire.SOLUTION: A pressure gauge 1 includes a main valve 101v that is pressed by air pressure when the air pressure transmitted from a tire side is a predetermined pressure value or more, and is retracted to an open position permitting the movement of air on the tire side and a compressed air supply source side, a pressure measuring portion 102 that measures the air pressure of the tire transmitted from the tire side, a check valve 101z that is provided between the main valve and the compressed air supply source, permits an air flow from the compressed air supply source toward the main valve, and cuts off a flow in the opposite direction, and a main valve opening/closing mechanism 104 that receives the operation force of an operator, moves the main value to an open position against elastic force energizing the main valve toward a closed position, and permits an air flow from the main valve toward the tire. A predetermined pressure value is lower than an upper limit value of a measurable pressure range set in the pressure measuring portion.SELECTED DRAWING: Figure 2

    【課題】閉位置に付勢する弾性力に抗して手動操作で弁を開位置に移動させて圧縮空気をタイヤへ供給する充填機能付き圧力ゲージにおいて、力の弱い操作者であっても容易に供給操作可能にする。【解決手段】タイヤ側から伝達される空気圧が所定圧力値以上であるときに該空気圧により押圧されてタイヤ側と圧縮空気供給源側の空気の移動を許容する開位置へと退避する主弁101vと、タイヤ側から伝達されるタイヤの空気圧を測る圧力測定部102と、主弁と圧縮空気供給源との間に設けられ、圧縮空気供給源から主弁に向かう空気の流れは許容し、逆方向の流れは遮断する逆止弁101zと、操作者の操作力を受けて、主弁を閉位置へ向けて付勢する弾性力に抗して開位置へ移動させ、主弁からタイヤに向かう空気の流れを許容する主弁開閉機構104と、を備える圧力ゲージ1であって、所定圧力値は、圧力測定部に設定されている測定可能圧力範囲の上限値よりも低い。【選択図】図2
