PROBLEM TO BE SOLVED: To provide a damper of low temperature dependency for use in a glove box and an ash tray for an automobile. SOLUTION: A narrow part 38 is formed in a base part side of a vane part 24 and made into a narrow width, so that the vane part 24 is easily elastically deformed and a clearance between an arc surface 24A of the vane part 24 and an inner circumferential wall 10A of a housing 10 is changed. For example, a viscous torque enlarged by the viscosity of viscous fluid formed in a projection part 40 of the vane part 24 due to increase in a viscosity coefficient is offset by enlarging the clearance by the increase in the elastic deformation of the vane part 24 and by reducing the viscous torque due to the viscous fluid passing flow rate formed in the projection part 40. The clearance between the arc surface 24A and the internal circumferential wall 10A is thus changed according to resistance receiving from the viscous fluid so as to offset an increase/decrease of the viscous torque and provide the damper 42 low in temperature dependency.
