摘要： An operating load of an overload releasing mechanism is made to be high by a simple method. In a webbing retractor, spring claws engage with recesses of a rotor, and a gear wheel and the rotor are connected. When relative rotational force is applied between the rotor and the gear wheel, the spring claws elastically deform and engagement thereof with the recesses is released. Due thereto, connection of the rotor and the gear wheel is released, and the overload releasing mechanism is operated. Here, urging members urge the spring claws toward a side of engaging with the recesses. Due thereto, the operating load of the overload releasing mechanism can be made to be high by a simple method of merely adding the urging members.

摘要： To obtain a webbing take-up device that can not only transmit to a take-up shaft only rotation from a motor by a clutch but is also simple and compact.A clutch of this webbing take-up device has a simply configuration where sliders 144 of a clutch body portion 114 are caused by frictional force to be retained in a case, whereby the sliders 144 and lock bars 154 are caused to relatively move and the lock bars 154 are caused by this relative movement to move to positions where they engage with or disengage from a ratchet 134. Consequently, the overall configuration of a clutch 100 can be made significantly compact (thinned) in comparison to a configuration that causes a pawl to move using an inertial disk that is large and has weight as in a conventional clutch. Thus, the overall configuration of a webbing take-up device 10 can be made compact.

摘要： A motor-driven seatbelt apparatus which enables easy re-restraining of a webbing even when an occupant releases the webbing temporarily from a restrained state. A control device senses the vehicle velocity with a vehicle-velocity sensor. When the vehicle velocity is a predetermined value or lower, the control device drives a motor to rotate a winding shaft, so that the webbing is wound into a completely wound state. When the vehicle is traveling at a vehicle velocity exceeding the predetermined value, the storing and winding operation of the winding shaft by the control device or the motor is not performed. Therefore, the occupant who temporarily released the webbing and finished an action such as to take out a small article in the cabin can re-restrain the webbing immediately thereafter.

摘要： A webbing retractor which allows one-way transmission of rotation from a motor by using a clutch, as well as achieving improved operation of pulling-out and taking-up of the webbing in ordinary use. In the clutch 100 of the present webbing retractor, a clutch main body 114 is not supported by a spool 20, but by a case (a clutch case 101 and a clutch cover 102) with a spindle 133 provided at an accommodating portion 132 of a rotor 124 at one side in an axial direction the spindle 133 being rotatably supported in a round hole 135 of the clutch cover 102 via a rotation support portion 175 of a holder 170, and with the accommodating portion 132 at the other side in the axial direction being rotatably supported by the clutch case 101 via a busing 112. Therefore, in the present webbing retractor, unless the clutch is in a connected state, the spool 20 can rotate independently of the clutch main body 114
