Abstract: There is provided a damper device for a glove compartment has a housing, a damping unit, a rack member and a gear. An insertion hole is formed through a bottom surface of the housing. The damping unit has a case which is fixed to the housing, and a rotation shaft which extends into an inside of the housing. The rack member is removably installed to the housing and is movable back and forth with respect to the housing. The gear is removably coupled to the rotation shaft through the insertion hole of the housing and meshes with the rack member. The case has a boss which protrudes into the housing and is received in the inside of the housing. The gear has a non-gear portion which is inserted to the insertion hole, and a flange which is in contact with the bottom surface of the housing.
