PROBLEM TO BE SOLVED: To provide a damper device and a steering device which reduce a contact sound caused by contact between members of the damper device, particularly, in a radial direction.SOLUTION: An impact absorption member (53) includes an impact receiving member (53a) having an annular part (532) capable of contacting with a contact end surface (51a) of a large diameter part (51), an elastic body (53b) which is arranged between the regulation surface (52b) and the annular part (532), has a radial clearance (S) with respect to an inner peripheral surface (52c) of a housing, is held by a housing (52) for large diameter part, and is formed from a rubber material or a synthetic resin material having rubber-like elasticity, and an elastic film (535a) which is bonded to the whole periphery of an outer peripheral surface (532d) of the annular part (532), is arranged on an inner peripheral surface (52c) of the housing with a radial clearance (G), and is formed from a rubber material or a synthetic resin material having rubber-like elasticity.SELECTED DRAWING: Figure 2 【課題】ダンパ装置の部材間の特に径方向の接触に起因して発生する接触音を低減するダンパ装置及びステアリング装置を提供する。【解決手段】衝撃吸収部材（５３）は、大径部（５１）の当接端面（５１ａ）に接触可能な円環部（５３２）を備える衝撃受部材（５３ａ）と、規制面（５２ｂ）と円環部（５３２）との間に配置され、ハウジングの内周面（５２ｃ）に対して径方向隙間（Ｓ１）を有し且つ大径部用ハウジング（５２）に保持され、ゴム材料又はゴム状弾性を有する合成樹脂材料で成形される弾性体（５３ｂ）と、円環部（５３２）の外周面（５３２ｄ）に全周に亘って接着され、ハウジングの内周面（５２ｃ）に対して径方向隙間（Ｇ）を有して配置されるゴム材料又はゴム状弾性を有する合成樹脂材料で成形される弾性膜（５３５ａ）と、を備える。【選択図】図２
