<p>A vibration type gas densitometer comprises a cylindrical vibrator, a cylinder body, to which one end of the cylindrical vibrator is fixed and in which the cylindrical vibrator is housed in concentric manner, and a casing, on which both ends of the cylinder body are supported and in which the cylinder body is housed in concentric manner. The vibration type gas densitometer further comprises first and second elastic bodies, respectively, provided between both end surfaces of the cylinder body and the casing for sealing between the cylinder body and the casing and for supporting the cylinder body from the casing in an axial direction of the cylinder body, and third and fourth elastic bodies, respectively, provided between peripheral surfaces on both end surfaces of the cylinder body and the casing for sealing between the cylinder body and the casing and for supporting the cylinder body from the casing in a diametrical direction of the cylinder body.</p> |
