  "textContent": "There is provided a damper device that can stably maintain a pulsation-preventing function obtained from the deformation of a diaphragm and can extend a service life by suppressing damage to the diaphragm. The damper device includes at least a diaphragm 4, an opposite member 5 that faces the diaphragm 4 and is connected to the diaphragm 4 in a hermetically sealed state over a circumferential direction, and a deformation-suppressing member 40 that is disposed in a hermetically sealed space M defined by the diaphragm 4 and the opposite member 5. The deformation-suppressing member 40 includes a central portion 41 that includes a concave surface 41a of which a depth is increased toward a center in a radial direction thereof, and protruding portions 43 that are provided closer to an outer peripheral side than the central portion 41.",
