To provide a seat belt retractor which can easily prevent abnormal noise caused by an impact energy absorbing wire.SOLUTION: A seat belt retractor includes: a winding drum 3; a locking base which is disposed so as to face a first end surface 31a at the first end 31 side of the winding drum 3; and an impact energy absorbing wire 4B which is housed in a slot 35 provided in the winding drum 3 and in which a head 43 is attached to the locking base. A resin bush 3A is attached to a second end 32 of the winding drum 3. The bush 3A has: an annular part 38 which covers an outer periphery of the second end 32 of the winding drum 3; and holding projections 39 which protrude from the annular part 38 and are inserted into the slot 35 through a second opening 37 of the slot 35. The holding projection 39 is disposed between a tip of the impact energy absorbing wire 4B and an inner surface of the slot 35.SELECTED DRAWING: Figure 6
【課題】衝撃エネルギー吸収ワイヤによる異音を容易に防止可能なシートベルト用リトラクタを提供する。【解決手段】シートベルト用リトラクタは、巻取ドラム3と、巻取ドラム3の第1端部31側の第1端面31aと対向するように配置されるロッキングベースと、巻取ドラム3に設けられたスロット35内に収容されるとともに頭部43がロッキングベースに取り付けられる衝撃エネルギー吸収ワイヤ4Bを含む。巻取ドラム3の第2端部32には樹脂製のブッシュ3Aが取り付けられ、ブッシュ3Aは、巻取ドラム3の第2端部32の外周を覆う環状部38と、環状部38から突出してスロット35の第2開口37を通じてスロット35内に挿入される保持突起39を有する。保持突起39は衝撃エネルギー吸収ワイヤ4Bの先端部とスロット35の内面との間に介在する。【選択図】図6
