Abstract: There is provided an acceleration sensor enabling precise positioning of a sensor lever of the acceleration sensor, for ensuring a stable operation of the acceleration sensor, and a seat belt retractor including the acceleration sensor. Shafts of a sensor lever projects from a base. The sensor lever is supported between supports of a sensor holder so as to be rotatable and shiftable in a rotation axis direction. The sensor lever is rotated by displacement of an inertia mass. A limiting portion of the sensor holder is brought into contact with contact portions of the sensor lever. The limiting portion limits shifting of the sensor lever in the rotation axis direction, so as to avoid contact between the base and the supports.

Abstract: When end lock has occurred in a seat belt retractor due to winding-up of a webbing, the end lock is easily and surely released. A stop part (6G) engages with a lock arm (40) displaced in a locking operation direction and stops the lock arm (40). A lock mechanism (9), in a state where the lock arm (40) stands still on the stop part (6G), starts operation with rotation in a pull-out direction (P) of a winding drum and stops rotation of the winding drum. A transmission mechanism (19) transmits rotation of the winding drum to the lock arm (40) and displaces the lock arm (40) in a release direction to release the engagement with the stop part (6G) is released between the time when operation of the lock mechanism (9) is started and the time when rotation of the winding drum is stopped. Release means (18) releases the engagement between the lock arm (40) and the stop part (6G) by the transmission mechanism (19).

Abstract: A lining material obtained by rolling a lining material sheet into a tubular form is installed in a conduit with both ends of the lining material sheet in its circumferential direction circumferentially overlapping each other. In this process, the lining material is installed so that, in a bending portion of a conduit, an overlapping portion where the both ends of the lining material sheet overlap each other faces toward an outer curvature side of the bending portion. Then, the diameter of the lining material installed in the conduit is expanded with the both ends of the lining material sheet circumferentially slid on each other. This facilitates inflation of a portion of the lining material which portion faces toward the outer curvature side in the bending portion, thereby decreasing a gap between the lining material and an inner surface of the bending portion.
