摘要： PROBLEM TO BE SOLVED: To exhibit sufficient sealing performance even if a part of a car body or an engine is dipped into the water by fitting an elastic seal cap to a rear end part of an elastic cap member, and sealing the rear end part of the elastic cap member. SOLUTION: An elastic seal cap member 9 is fitted to a rear end part of an elastic cap member 8, and its attaching structure is carried out in such a way that a fitting cylindrical body 8-6 having a diameter smaller than an outer diameter of a cap member 8 is protruded to a rear end part of an elastic cap member 8, and a cylindrical elastic seal cap 9 having the same outer diameter as the outer diameter of the elastic cap member 8 is fitted to the fitting cylindrical body 8-6 by a recessed and projection fitting method. In the cylindrical elastic seal cap 9, a through-hole 9-1 having a diameter smaller than the outer diameter of a tube P which is connected, and which is nearly matched is protruded on a center part, and a locking part 9-2 for recessed and projection- fitting the elastic cap member 8 as a counterpart is formed on an outer circumferential end part.

摘要： PROBLEM TO BE SOLVED: To provide a connector regularly having dust preventing effect regardless of before and after the connection to piping and connectable without any trouble in the connecting work of the piping by mounting an elastic cap member from the rear end side of a connector body to enclose an engaging hole part or cutout window part by its cylindrical wall. SOLUTION: In carrying or storage before connection of piping P, an elastic cap member 8 consisting of a bottomed cylinder is preliminarily mounted from the rear end side of a connector body 1 to enclose a cutout window 1-1 part by its cylindrical wall 8-4, and a locking part 8-5 is preferably engaged with a stepped part 1-3 on the circumferential part of the connector body 1 to hold the elastic cap member 8 in a prescribed position of the circumferential part of the connector body 1. When the carrying or storage is performed in this state, intrusion of dust through the rear end part or cutout window 1-1 of the connector body 1 can be prevented by the elastic cap member 8. Accordingly, the connector regularly has dust-preventing effect, and is connectable without any trouble in the connecting work of the piping.

摘要： PROBLEM TO BE SOLVED: To miniaturize the whole joint through axially short-sized structure by providing a base part movably at an opening end part of a joint body through a support member protrusively provided with a cylindrical insert, and pressing a claw wall part inward by contact engagement with an inclined face of the joint body. SOLUTION: In association with the simultaneous follow-up movement of a collet member 4 caused by slight retreat of a resin tube P after being fitted into an insert 3' part and insert-fitted into a space part, a claw wall part is pressed inward to bite into the peripheral surface of the resin tube P by contact engagement with an inclined face 2' on the joint body 1 side at an outer part of a claw wall 4'. In case of releasing the resin tube P, thread-fastening to an opposed member through thread parts 1''' of the joint body 1 is unfastened, and then the resin tube P is released immediately from a flareless state at a claw wall 4' part by slight forward pressing movement of the tube. Miniaturization can be attained through the axially short-sized structure of the joint body.

摘要： PROBLEM TO BE SOLVED: To ensure the mechanical strength on the piping side near a connecting part and prevent the crack and breakage of a piping by vibration by forming a stopper wall, a guide chamber and a hook wall on a connecting hole part, relatively pressing an inserted piping in the axial direction, and connecting the end part vicinity of the piping by a swollen wall by plastic deformation. SOLUTION: A joint body 1 side or a piping P side is relatively pressed from the outside in the axial direction to bring the connecting end part of the piping P into contact with the middle inclined wall surface formed by the guide chamber 3 of a connecting hole 1', and the end part of the piping P is engagingly locked by a stopper wall 2 part. According to further pressing, an outward swollen part P' conformed to the guide chamber 3 is formed by plastic deformation in the part situated in the guide chamber 3 near the piping P end part, and its neck lower part is engaged with a hook wall 4 and connected. Thus, brazing in a connecting part is dispensed with, the connection can be easily performed by simple pressing, the influence on mechanical strength on the piping P side near the connecting part is thus eliminated, and the crack or breakage can be avoided even in a piping state under vibration.

摘要： PROBLEM TO BE SOLVED: To eliminate an other joint, a stopper member and a releasing member of a connecting portion to thereby simplify an interior-furnishing structure, by interior furnishing a collet member such that it can be freely moved in an axial direction and by pressing a claw wall inward and biting in it in the outer peripheral surface of a resin tube by butting it into contact with the slant wall of the connecting portion. SOLUTION: In a connecting portion 1, and collet member 4 having a cylindrical base part 4''' connecting to an elastic slit wall 4a which has an inward claw wall 4' at the tip end and a projecting wall 4'' made on the outer periphery side thereof and elastic sealing members 3 on the inner and outer peripheral surfaces of the base part 4''' is interior furnished such that it can be freely moved in the axial direction. After a resin tube P' fitted on an inserting member 2 is inserted into a room 1' with an enlarged diameter, or after a resin tube P' is fitted on the outer peripheral surface of an inserting member previously inserted, if the resin tube P' is slightly pulled backward, the collet member 4 follows the pulled-back resin tube P' to put the projecting wall 4'' into contact with the slant wall 1'', whereby the claw wall 4' is passed and bit in the outer peripheral surface of the resin tube P', which connects a metal pipe P to the resin tube P'.

摘要： PROBLEM TO BE SOLVED: To form the whole of a connector in a compact manner and to simplify connection and disconnection at a limited space. SOLUTION: A resilient seal ring member 6 and a cylinder annular bush member 7 are arranged internally of the small chamber part 3' of a connector body made of resin and a tongue-form wall 8 having a catching means 8' and a lever is arranged integrally with a notch window groove part 1' formed in the opposite position of the peripheral wall part of a large chamber 3. The window groove part has the other catching means 5'" fitted in the catch means 8'. A retainer member 5 having the tip side forming a claw wall 5' is arranged internally of the catching means. In the connection state of a piping P, an annular expansion expansion wall part P' incorporated in an interior through the tip part of the claw wall 5' is brought into engagement with a pressure. Further, during release, through simultaneous bending of a tongue-form wall occasioned by pull of a lever to the outside of the lever or simultaneous bending of the tongue-form wall occasioned by press, the claw wall part is released from pressure engagement.
