Abstract
A seat belt retractor having a main pawl (17) which is rotatably fitted in a fourth recess (4n) provided in a reel shaft (4). In this state, a load transfer portion (17e) abuts on a load bearing surface (4j) of the reel shaft (4). Since the load transfer portion (17e) abuts on the load bearing surface (4j) of the reel shaft (4), a load (w) applied to a pawl portion (17c) of the main pawl (17) is transferred from the load transfer portion (17e) to the load bearing surface (4j) and borne by the reel shaft (4). Since teeth (17d), which serve as a point of application of load, and the load transfer portion (17e) are relatively close to each other, the main pawl (17) is subjected to only compressive force substantially. Moreover, since the load transfer portion (17e) and the load bearing surface (4j) are in plane contact with each other and hence the load is transferred to the reel shaft (4) while being dispersed over a wide area, the stress produced therein is relatively small.
