Provided is a damper device capable of increasing torque of a coil spring without increasing an outer diameter of a case. The damper device includes the case (), a shaft () that is relatively rotatable with respect to the case (), fluid filled in a damper chamber () formed between the case () and the shaft (), a bearing member () that forms a partition wall () that closes one end of the damper chamber () in an axial direction and is separate from the shaft (), and a coil spring () having one end connected to a side of the case () and the other end connected to the shaft () or the bearing member () to apply torque to the shaft () with respect to the case (). The bearing member () is arranged between a winding portion () of the coil spring () and the damper chamber.
