摘要： In a webbing take-up device, a lock ring of an energy absorption mechanism is disposed coaxially to a spool. An anchor hook (one end portion) of a wire is anchored to the lock ring, and the wire is wound around a wire attachment face (outer peripheral portion) of the lock ring from the anchor hook to another end portion of the wire. Most of the wire excluding a second energy absorption portion is accordingly disposed around the wire attachment face of the lock ring that is disposed coaxially to the spool, thereby enabling an increase in size of the body of the webbing take-up device to be suppressed in comparison to a case in which the lock ring is disposed parallel to the spool.

摘要： A serrated portion is formed on an outer peripheral portion of a lock base body of a lock base of a webbing take-up device. Furthermore, a flange portion is formed on the outer peripheral portion of the lock base body. The flange portion is disposed on a vehicle front side with respect to the serrated portion. Triangular grooves of the serrated portion are closed by the flange portion. When the lock base becomes displaced in a vehicle rearward direction and the flange portion comes into abutting contact with a leg plate of a frame, further displacement of the lock base in the vehicle rearward direction is blocked. Due to this, engagement between the serrated portion and ratchet teeth of a ratchet hole in the leg plate can be maintained.

摘要： In a webbing take-up device, a FL lock pawl is actuated by rotation of a spool in a pull-out direction relative to a lock base, coupling the spool and a lock ring of an energy absorption mechanism together by the FL lock pawl. A reduction in number of times the FL lock pawl is actuated is thereby enabled in comparison to a case in which the FL lock pawl always actuates on actuation of a lock mechanism. The occurrence of wear or the like of ratchet teeth of the FL lock pawl is suppressed as a result. Accordingly, improvement of margin for durability of the FL lock pawl that actuates the energy absorption mechanism is enabled.

摘要： In a webbing retractor device, a compression coil spring is suspended between an engagement frame of a V-gear and an engagement surface of a locking base. As a result of the engagement frame being engaged with from an exposed portion side by the compression coil spring that is being held in a holding groove of the locking base so as to be exposed to the exposed portion side, the compression coil spring is suspended between the V-gear and the locking base. Because of this, the compression coil spring can be easily suspended between the V-gear and the locking base.
