The base member includes a natural fiber or a glass fiber and a first thermoplastic resin fiber and has a density of 0.2 to 0.7 g/cm3 The surface member includes a second thermoplastic resin fiber and a low melting point resin fiber and that has a weight per unit area of 50 to 500 g/m2. The surface member is laid on a surface of the base member. An entangled layer where the second thermoplastic resin fiber enters texture of the base member to be entangled with the first thermoplastic resin fiber is provided at an interface between the base member and the surface member.

Abstract: An object is to provide a spin welding component that has a simple configuration of a welding surface and provides enhanced welding strength. A spin welding component 1 includes a shaft portion 2 formed in an approximately columnar shape, a flange portion 3 extended outward from below the shaft portion 2 to be formed in a disk-like shape, and an opening 4 formed by opening part of a bottom face of the flange portion 3. A molten resin 9 as molten material is applied on the bottom face. High-speed rotation causes the molten resin 9 to be melted by the frictional heat, and part of the molten resin 9 enters the opening 4 to be welded.

Abstract: The objective of the present invention is to efficiently and inexpensively mass-produce a sound insulator for a vehicle which is light in weight and has excellent sound insulating properties. For this purpose, the ultra-light sound insulator of the present invention is composed of a felt single sheet 3 having a vehicle interior side surface 1 and a vehicle exterior side surface 2 and being thermoformed of cotton fibers and binder fibers which are tangled and contacted and jointed to each other in a random manner. The ratio of the stiffness of the vehicle interior side surface 1 to that of the vehicle exterior side surface 2 is set to be in a range of 1.1 to 10. The single sheet 3 also has an area of gradually-decreasing stiffness 4 that spreads over at least one part of the area between the vehicle interior side surface 1 and the vehicle exterior side surface 2.
