  • Patent number: 7458185
    Abstract: A belt molding structure for motor vehicles includes a molding body including a resiliently-deformable anti-vibration lip which is integrally formed on an inner surface of the molding body; an end cap attachable to an end of the molding body, and including an insertion portion; a lip-escape space, provided inside the molding body so as not to interfere with the insertion portion of the end cap, for allowing at least a portion of the anti-vibration lip to come into the lip-escape space when the anti-vibration lip is deformed; and a deforming guide surface formed on the end cap in a vicinity of an insertion end of the insertion portion to resiliently deform the anti-vibration lip into the lip-escape space when the insertion portion is inserted into the molding body.

  • Patent number: 6082939
    Abstract: In a machine tool having a worktable feed mechanism of the type that a worktable is moved in a horizontal direction relative to a tool spindle along a pair of guideways in parallel with the horizontal direction, there is provided a cutting chips collection space formed between the pair of guideways fixed to a base. A pair of ball screws are arranged outside of the cutting chips collection space for moving the worktable relative to the tool spindle in the horizontal direction. The cutting chips and coolant generated by contacting a tool with a workpiece drop into the cutting chips collection space directly without being heaped onto a cover mechanism of the worktable feed mechanism.
