摘要： PURPOSE: To make the check of connection easy enough, extending the range of application, and further to make the check of slipout or fallout from the outside yet easier by means of an elastic claw wall and a check member or an easy-to-see positional relationship of a projecting wall even in a narrow, complicated connective place. CONSTITUTION: A seal ring member 6 and a bush member 7 both are installed in a small diametral chamber 3' part of a connector 1 piercingly installed with this diametrally expanded small diametral chamber 3' and a large diametral chamber 3 ranging to a flow hole 4 in the inner part of a shaft center. In addition, plural pieces of elastic claw walls 5 being surrounded by an almost U-shaped notch part 5' along the circumferential surface direction and energized inward aslant, is installed in a peripheral wall 1' part of the large diametral chamber 3', while in time of connecting a pipeline P, a bottom surface interposed in a gap part 9 with a side face of the notch part 5' being opposed to a free tip part of the claw wall is slipped or dropped out with contactual engagement to an annular bulge wall P' at the piping side, while this bulge wall is resiliently engaged and pressed with the sidepiece at the vicinity of a tip of the claw wall 5.

摘要： PURPOSE:To ensure rigidity, restrain deformation and prevent oil leak while facilitating working by molding a portion of a fuel delivery pipe with resin. CONSTITUTION:A cylindrical socket 12 for mounting a fuel injection valve is molded into a primary assembly. The socket 12 is composed of a tubular extension part 21 receiving a fuel injection valve and a band part 22 wound around a communicating pipe 11, which are integrally molded with synthetic resin. Thus, fuel supplied from central opening 23 of a flange 13 is sent through a fuel supply path 17 in the communicating pipe 11 from a hole 18 in a side wall into the fuel injection valve (injector) fitted into the tubular extension part 21 of the socket. Since a portion of a fuel delivery pipe is thus molded with resin, a portion of mechanical working processes can be omitted and the working is facilitated.

摘要： PURPOSE:To install an insert-allowance accurately in a thin member with a simple device by setting put an inside die at the backside, compressing and deforming the central part of a setting objective part in pressing the tip of a pressing rod from the surface side and, after deforming the outer circumference and projecting it to the surface side, piercing it through by means of punching. CONSTITUTION:An inside die 2 is set up at the backside of a setting objective part of a thin wall member 1, pressing the surface side of this setting objective part with a circular part 4 of a pressing rod 3, and a central part of the setting objective part is compressed and deformed, while an outer circumference of this compressed-deformed part 5 is deformed and projected to the surface side, thereby forming a ring projection 6. Then, a punching die 12 is set up on the backside of the setting objective part, and the compressed-deformed part 5 on an inner circumference of the ring projection 6 is punched out, piercing a mounting port 11 through the compressed-deformed part 5, and an insert-allowance 14 is installed in the thin-wall member 1. Thus, even in the solid-form thin-wall member 1 such as a small diametral pipe or the like where an operating space is not taken on the backside, not to mention the platelike thin-wall member 1, the insert-allowance 14 is made installable by a simple and small device by adding external force from the surface side of the thin-wall member 1.
