<p>An innovative and highly practical level that is excellent in mass productivity, where the position of a bubble can be conveniently corrected, and that is cost effective. An installation body (2) is installed on a device body case (3) so as to be finely pivotable about a shaft member (7). The installation body (2) has an elastic contact section (8) coming into elastic contact with the inner surface of one side of the device body case (3), and also has an adjustment screw (9) or a fastening/pressing contact section (12). The adjustment screw (9) comes into pressing contact with the inner surface of the side opposite the one side of the device body case (3). The fastening/pressing contact section (12) comes into pressing contact with the inner surface of the side opposite the one side of the device body case (3) by tightening of the adjustment screw (9). The adjustment screw (9) is turned to adjust the degree of its threaded engagement, which varies the degree of elasticity of the elastic contact section (8) to fix the installation body (2) to the device body case (3). Further, the installation section (2) is adjustable relative to the device body case (3) in a finely pivoting manner to correct the position of a bubble of a bubble tube measurement section (1).</p> |
