摘要： A connecting structure of an externally resin-coated small-diameter metallic pipe having an excellent corrosion-resistant property with respect to a mating member is provided. According to the present invention, a resin-uncovered portion of the metallic pipe provided for applying an end processing thereon is completely covered with a protective pipe made of a resin material so that the processed pipe can be connected with the mating member without spoiling its anti-chipping property and an anti-splashing property of the metallic pipe over the entire length thereof. With the exception of the end of the metallic pipe corresponding to the margin at least required for applying an end processing on the pipe, the pipe is covered with an extrusion-moldable thick film-like resin and is connected with a mating member by means of a clamp nut assembled to the pipe end so as to be screw-fitted with the mating member. The connecting structure according to this invention features that one end of a resin pipe is fitted about the above-described resin coated layer on the metallic pipe while the other end of the resin pipe is inserted into, or fitted about, the clamp nut and the resin pipe is fixed to the clamp nut at least at a single portion thereof.

摘要： A multi-layered metallic pipe having resistances to the chipping of pebbles and splashing of muddy water while driving a vehicle and excellent corrosion resistances. The multi-layered metallic pipe is piped without scraping and does not need an insulator. The multi-layered metallic pipe includes a metallic pipe having a relatively small plated diameter with a film made of zinc, aluminum or a zinc/aluminum based alloy on the outer circumference of the metallic pipe. A first layer of a polyamide resin, a polyviny fluoride, or a polyvinylidene fluoride having a film thickness of 20 to 50 microns is applied to the plated film. A second layer made of an extrudible resin having a film thickness of 100 microns to 1.0 millimeter and a chipping resistance is coated over the first layer along an entire length of the first layer. The second layer is formed to have stepped portions of different thickness. A method of coating the multi-layered metallic pipe includes forming the first layer on the outer circumference of the plated metallic pipe and the subsequent step of forming the second layer with stepped portions of different thicknesses by extruding the resin at an intermittently different feed rate.

摘要： A small-diameter resin tube connecting structure used as a small-diameter tube connector is provided. The connector comprises: a main body including therein a small-diameter chamber continuous with a communication hole defined by the connecting cylindrical wall at the top end of the main body and a large-diameter chamber formed behind the small-diameter chamber; and a socket having repulsive walls each in the form of a pawl wall and formed integral with, or separately from, the outer periphery of the connector main body whereby the repulsive walls of the socket are brought into engagement with an annular bulged wall of the target resin tube. Further, a thin-wall metallic tube having an annular bulged wall is inserted into at least the connecting end of the resin tube with the metallic tube serving as a reinforcing member for the resin tube. The resin tube may have the annular bulged wall together with the metallic tube by press-working the inserted metallic tube in the axial direction. The connector of the present invention can securely maintain the connection of the target small-diameter tube with the connector for a prolonged period of time, increase the resistance against the draw-out force and manufacture easily and in a simple manner without enlarging the size thereof.

摘要： A plating hooking apparatus incorporated into an automatic conveyer permits plate-objects to rotate in and above a plating tank. This apparatus has a current conduction bar extending over the plating tank, hung-down rods suspended from the current conduction bar, hooking jigs rotatably secured to the lower ends of the hung-down rods, a driven rod engaging with a driving unit to move laterally and drive transmission means for rotating the hooking jigs by propagating the lateral movement of the driven rod to the hooking jigs. The drive transmission means includes a rack, a pinion, first means for converting a rotation of the pinion into a rectilinear motion, second means for converting the rectilinear motion into a rotary motion and means for propagating the rotary motion to the hooking jigs. With this arrangement, the hooking jigs are capable of rotating in and above the plating tank.
