<p>Provided is a Bourdon tube pressure gauge comprising a tube support (5) of a resin having a pressure introducing passage (3) for supporting a Bourdon tube (1). The tube support (5) has a tube end fitting hole (H) extending from a side face (5a) and communicating with the opening (3a) of the pressure introducing passage (3), and a first through hole (h1) extending from an upper face (5b) through the confronting hole walls (W) of the tube end fitting hole (H). The Bourdon tube (1) has such second through holes (h2) in the confronting tube walls (w) of an end side (1b) as register with the first through hole (h1) when the tube end (1b) is inserted into the tube end fitting hole (H), and has a safety pin (8) press-fitted from the upper face (5b) into the first through hole (h1) and the second through holes (h2). An adhesive material (M) can exist between the outer face of the tube end (1b) of the Bourdon tube (1) and the inner face of the tube end fitting hole (H), thereby to prevent the pressure release.</p> |
