The muffler includes a porous plate which is disposed inside of the outer case, and which is connected to an exhaust pipe, and the porous plate is operatively connected to an outlet pipe which discharges an exhaust gas to the outside environment through an opening formed in an outlet side of the outer case. In one embodiment, the inner sleeves are arranged substantially parallel to each other, and are fluidly connected to a joint exhaust feed pipe disposed inside the outer case. The inner sleeves are connected to the outlet pipe on the outlet side of the outer case.

The sealing and pump-up device 10 includes: a liquid agent container 18 containing a sealing agent 32; an injection unit 20 that is connected to an outlet 29 of the liquid agent container 18 and has a liquid pressurization and supply chamber 40 and a jig insertion hole 44; a jig 82 that by insertion into the jig insertion hole 44 pierces an aluminum seal 30 by means of a piercing member 62 and closes off the jig insertion hole 44; and a leading end portion 85, of an insertion portion 84, having a step 85A that catches on an edge 44B of a jig insertion hole 44 before the jig 82 that has been inserted into the jig insertion hole 44 reaches a piercing position, when the aluminum seal 30 is pierced. The jig 82 has simple installation and can be reliably operated because the jig 82 does not come out even when subjected to pressure.

Abstract: When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96.

Both of the bottom and top insulating resin layers have a structure that is a combination of a resin which is changed to cohesiveness when heated and which undergoes smaller plastic deformation when heated to a higher temperature and an insulating resin layer which has a thickness sufficient to maintain insulation between the electronic part or a conductor of the core and the wiring layer and which inherently undergoes small plastic deformation.
