摘要： PURPOSE:To adhere a fibrous sheet on the surface of a hollow body and to prevent the fibrous sheet from peeling, by forming a recess for a projected stripe in an inner side of a pinch-off part of one of the divided molds, pressing thereby a parison and a fibrous sheet when mold-clamping is done, and forming a plastic hollow body having a tightly adhered projected stripe. CONSTITUTION:A thermoplastic parison 12 is fed downward between divided molds 13 and 14 from an extrusion die 11 and a fibrous sheet 17 is fed downward in advance between the parison 12 and the divided mold 13. The divided molds 13 and 14 are clamped and the parison 12 is sealed and at the same time a compressed fluid is introduced in the parison 12 by means of a blowing nozzle. A hollow plate member 2 is formed by cooling and solidifying the parison and a fibrous sheet member 3 is formed by adhering the fibrous sheet 17 on the surface. A projection 5 on the circumference of the hollow plate member 2 is formed by pressing at the mold-clamping and the molten plastic is tightly penetrated in the meshes of the fibrous sheet 12, which is thereby tightly adhered. Only the fibrous sheet 17 is left on the jointed faces 19 and 22 and a flash and a rear parcel shelf are jointed. The rear parcel shelf can be obtained by cutting off the part A-A of a molded item.

摘要： PROBLEM TO BE SOLVED: To provide a folding container in which the fitting of shafts of side walls can easily be performed with respect to a bottom wall and which causes no shaft fall-off. SOLUTION: The folding container is constituted with a pair of side walls 2a and 2b opposed to each other and another pair of side walls 2c and 2d opposed to each other, each side wall being connected to each side of a bottom wall 1 in such a manner that they are freely raised upright and laid flat. A slant surface 8a extending in the direction of a shaft end is formed on each of projecting shafts 8 provided at both ends of each side wall. A slant surface 9a to which the slant surface 8a of each shaft 8 is opposed and which fits and guides each shaft 8 to a shaft hole 9 is formed at a shaft receiving portion 1a at which a shaft stop of each shaft 8 is performed.

摘要： PURPOSE:To provide a boot with which no slip in axial direction is generated between the boot fixing part and a member to be mounted and which presents a high sealing strength. CONSTITUTION:A boot concerned has bellows and a fixing part 3 tightly attached sealedly to a member to be mounted at each end of bellows. A ring- shaped recess 6 to mount a fastener is formed at the peripheral surface of at least one of the fixing parts 3, while a ring-shaped groove 8 is formed at this recess 6, and a tight attaching member 10 made from a hard material is fitted in this ring-shaped groove 8. A ring-shaped ridge 9 mating with the groove 8 is formed at the inside circumferential surface of the fixing part 3.

摘要： PURPOSE:To obtain a fixing structure of a boot which generates no slippage between a fixing part of the boot and a boot-installed member, and has an extremely high sealing strength. CONSTITUTION:A bellows, and fixing parts 2 sealed closely to the outer rings 10 of constant velocity joints to be the installed members to both ends of the bellows, are provided. On the outer peripheral surface of at least one side fixing part 3, a ring-form recess 6 a clamp is installed is formed. On the outer peripheral edge of the ring-form recess 6, a ring-form recessed gloove 8 is formed at almost the center in the axial direction. On the inner peripheral surface of the ring-form recess 6, a ring-form projection 9 corresponding to the ring-form recessed groove 8 is formed. The ring-form projection 9 is formed in the form contacting to a straight line B making the angle beta to a center line A orthogonal to the axial line direction 50 deg. to 65 deg.. A ring recessed groove 11 corresponding to the ring-form projection 9 is formed to the outer ring 10 of the constant velocity joint.

摘要： PURPOSE:To improve flexibility in a bending direction of valley parts constituting a part of the bellows of boots and prevent the generation of a crack on this part without the generation of a concentrated stress by this flexural deflection in the entire valleys. CONSTITUTION:Ring shaped grooves opened outward are arranged in the bottom part of at least two valleys among plural valleys 61-66 of bellows 4. The back side shape of this valley is made in nearly similar figure to the ring shaped groove and also reversed shaped recessed parts are arranged on the connection part of this back side surface with the back surface of the slant surface 7 of the bellows 4. Further, the bellows are formed with an elastic material whose tensile elasticity is 100-1000 kg/cm .
