Abstract: The tang portion of a clamp member of the carpet clamp deforms elastically, and thus the portion which holds a wire harness can be moved. Further, the tang portion is pressed (deformed) in the direction of a bottom wall by a groove portion. Thus the tang portion fits to the wire harnesses having different diameters. Further, in the case where the wire harness has a small diameter, the tang portion of the clamp member deforms elastically, and thus the portion which holds the wire harness is moved, and thus the outside dimension of the carpet clamp becomes substantially small in accordance with the wire harness having a small diameter. The carpet clamp has a height which is smaller by a dimension than in the case where the wire harness has a large diameter.

Abstract: A webbing take-up device with a small difference in a frictional force between an outermost layer portion of a spiral spring along a circumferential direction of a rotating body and an inner peripheral portion of the rotating body is obtained. A reduction sliding spring is formed in a curved shape, such that the radius of curvature becomes gradually larger in a predetermined ratio toward a longitudinal central portion from both longitudinal ends in a state where the reduction sliding spring has not been elastically deformed in a circular shape. The amount of elastic deformation accompanying a minute change in a position from the longitudinal central portion to both longitudinal ends becomes approximately equal in a state where the reduction sliding spring has been elastically deformed in the circular shape. Therefore, a radially outward elastic force having substantially a center of the reduction sliding spring as its center becomes approximately equal.

Abstract: A webbing take-up device which can improve the workability of the assembly work of a tension reducer is obtained. In this webbing take-up device, a take-up spring unit is arranged closer to the opening side of a case than a reduction spring unit within a case. For this reason, when a clutch is arranged inside the reduction balance spring and the inner end of the reduction balance spring in a spiral direction is locked to a spring case of the clutch, the clutch and the reduction balance spring can be easily and visually recognized from the opening side of the case. Thus, the other end of the reduction balance spring can be easily locked to the spring case.

Abstract: 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.

Abstract: In a V-sensor of a webbing take-up device, concave portions are formed in supporting walls of a supporting member having a spring property, and peak ends of a rotating shaft of a sensor pawl gets into the concave portions, and the rotating shaft is thereby supported by the supporting walls. Cone-shaped concave portions come into contact by pressure with the cone-shaped peak ends of the rotating shaft due to the elasticity of the supporting walls, and therefore, when the rotating shaft attempts to be displaced in the axis direction thereof and in a direction orthogonal to the axis direction of the rotating shaft, the elasticity of the supporting walls withstand displacement of the rotating shaft. As a result, occurrence of a rattle of the rotating shaft, that is, the sensor pawl can be prevented or restrained.

Abstract: A webbing retracting device that may prevent entering of an end-lock state when a spool rotates in the pull out direction on rebound just after completion of taking up of the webbing belt. A restriction weight is provided on a V gear. The restriction weight moves in the pull out direction relative to the V gear by acceleration when the V gear is rotated in the take up direction, and furthermore, the restriction weight pivots about a support pin under centrifugal force due to rotation of the V gear and attains a contact position. In such a state, even if the inertial mass attempts to displace toward the lock activation direction, the restriction weight interferes with the inertial mass and restricts displacement of the inertial mass toward the lock activation direction.

Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.
