    • PROBLEM TO BE SOLVED: To ensure sufficient weld strength by inhibiting defective welding from being caused when welding two tubular bodies forming the case of an oil strainer by spin welding to reduce costs. SOLUTION: The inlet side tubular body 11 is formed at an end with an inlet side weld portion 28 which projects toward the outlet side tubular body 10 and circularly extends. The outlet side tubular body 10 is formed at an end with an outlet side weld portion 21 which projects toward the inlet side tubular body 11 and circularly extends to be along the inlet side weld portion 28. The tip in the projecting direction of the inlet side weld portion 28 is formed with a slanting surface portion 28a. The both tubular bodies 10, 11 are united with the slanting surface portion 28a welded to the outlet side weld portion 21 by the spin welding. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:通过在通过旋转焊接来形成油过滤器的情况下焊接两个管状体时,通过抑制不良焊接来确保足够的焊接强度,以降低成本。 解决方案:入口侧管状体11在其端部形成有朝向出口侧管状体10突出并圆形延伸的入口侧焊接部28。 出口侧管体10的一端形成有出口侧焊接部21,其朝向入口侧管状体11突出并且沿着入口侧焊接部28圆形延伸。入口侧的突出方向的尖端 焊接部分28形成有倾斜表面部分28a。 两个管状体10,11与通过旋转焊接焊接到出口侧焊接部分21的倾斜表面部分28a相结合。 版权所有(C)2008,JPO&INPIT
