According to one embodiment, a measuring system using an optical waveguide is provided. The measuring system has an optical waveguide, magnetic fine particles, a magnetic field applying unit, a light source and a light receiving element. The optical waveguide has a sensing area to which first substances having a property of specifically bonding to subject substances to be measured are fixed. Second substances having a property of specifically bonding to the subject substances are fixed to the magnetic fine particle. The magnetic field applying unit generates a magnetic field for moving the magnetic fine particles. The light source inputs a light into the optical waveguide. The light receiving element receives the light output from the optical waveguide.

A kinetic-energy absorbing member absorbs the kinetic energy of a pull-in member such as a buckle or a lap anchor when reaching a bottom position. The kinetic-energy absorbing member, which includes a thin-walled tubular member that may be made of metal such as iron or aluminum, is arranged between a bracket and buckle. As the pretensioner is actuated, the buckle is pulled by a wire, thereby depressing the kinetic-energy absorbing member against the bracket so that the kinetic-energy absorbing member collapses and the kinetic energy of the buckle is absorbed when reaching the bottom position.

A pre-tensioner capable of effectively absorbing kinetic energy exerted on a coupling member connected to a piston during operation. As a gas generator is actuated to generate gas in the event of emergency, the gas is introduced into a pressure chamber. By gas pressure of the gas, a piston moves at high speed toward a taper portion of a cylinder to reach the taper portion. According to the movement of the piston, a buckle is pulled toward a bracket so that the buckle is about to reach the bottom. After that, the piston further moves to the left while deforming the taper portion. The deformation of the taper portion absorbs kinetic energy of the piston. Therefore, kinetic energy of the buckle is absorbed so as to stop the buckle softly and the impact is buffered.
