摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine wherein a work to mount and demount an ignition coil is facilitated. SOLUTION: A design cover 4 presses and energizes a head part 3a of an ignition coil 3 contained in a coil containing part 2a of an engine head cover 2. Thus, during mounting and demounting of the ignition coil 3, a work to fasten or loosen a screw is not needed, and a remarkable improvement of the efficiency of a work to mount and demount the ignition coil 3 is effected.

摘要： PROBLEM TO BE SOLVED: To provide a waterproofing structure of a connector whose parts number is reduced in order to realize cost reduction.
SOLUTION: A case 11 and the first connector 13 of an electronic control device 100 have an overlapping structure at a lap portion 15, and a covering member 22 of the second connector 19 covers the lap portion 15 from outside. Both the first connector 13 and the second connector 19 are joined hermetically since a packing 23 is disposed between the covering member 22 and the lap portion 15. Waterproofing is achieved only with the packing 23 between the first connector 13 and the second connector 19. Consequently, a packing between the case 11 and the first connector 13 required hitherto can be saved, and cost reduction becomes possible because of parts number reduction.

摘要： PROBLEM TO BE SOLVED: To prevent an operation lever from catching or obstructing in carrying and wire harness assembling, and to prevent the operation lever from being overturned, so as to prevent surely the operation lever from being damaged. SOLUTION: In this low insertion force lever connector 10 of the present invention, an operation lever attaching part 11g having a step of a thickness T of the operation lever 13 or more is formed on the outer surface of a female connector housing 11, and the operation lever 13 having a cam groove 13f is fixed turnably to the operation lever attaching part 11g. When the operation lever 13 is turned, a mating connector housing is engaged with the inside of the female connector housing 11, one side end part of the operation lever 13 is brought into contact with an end part of the operation lever attaching part 11g when the lever 13 is turned further thereafter, so as to block the overturn of the operation lever 13.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device in which a strain of an injector caused by its fitting is reduced and an injecting characteristic of the injector is kept. SOLUTION: An injector body 11 and a nozzle body 20 hold a spacer 21 and are connected by a retaining nut 22. A flange part 22c of the retaining nut 22 is placed at an end part in the injector fixing direction at a threaded coupling part between the injector body 11 and the retaining nut 22, i.e., an injector fixing direction side rather than the end part opposite to the injector fixing direction at the threaded coupling part and then abutted against a cylinder screw 60. Since an axial length of the cylinder screw 60 to which a fastening force is applied is short, an amount of strain of the members constituting the injector 10 is decreased and then a fluctuation of fuel injecting characteristic can be restricted.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injector in which an injector can be easily mounted on an engine head and the injector can be easily removed from the engine head by a simple constitution and the injector removed can be reused. SOLUTION: A cylinder screw 60 is formed into a cylindrical shape and a male screw part 60a formed on an outer peripheral wall is screw-coupled with a female screw part 2a formed on an inside wall of a mounting hole 2. In a state before an injector 10 is mounted on an engine head 1, the cylinder screw 60 is axially and freely movably assembled between a tapered surface 11b and a flange part 22c. The injector 10 can be easily mounted on the engine head 1 and be easily removed from the engine head 1 by a cylinder screw 60 by pressing the tapered surface 11b by the cylinder screw 60 in a direction that the injector 10 is removed from the engine head 1.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injector easily performing an assembling work. SOLUTION: A stopper 40 is formed into an annular-shape and has a projecting part 41 projecting to the outside in the diameter direction. A positioning groove 3a extends in parallel to the mounting direction of an injector 10. By inserting the projecting part 41 in the positioning groove 3a, the projecting part 41 is restrained by the positioning groove 3a in both the revolving directions of the injector 10. Therefore, the mounting work of the injector 10 and the connecting work of a fuel piping 50 become easy because the revolution of the injector 10 is regulated when the works are performed. The injection characteristic of the injector 10 can be held because torsional force when the fuel piping 50 is connected does not work on magnetic circuit constitution members and injection quantity metering members.

摘要： PURPOSE:To secure a sealing property between a cylinder head and a cylinder head cover by preventing yielding of a fastening seat surface caused by a bolt. CONSTITUTION:A bolt hole 2 is formed in a cylinder head 1, and a screw hole 5 is also formed in a cylinder head cover 3. The cylinder head cover 3 is placed on the cylinder head 1 by interposing a gasket 7 between them, and while using one edge side periphery of the bolt hole 2 as a fastening seat surface 9, a bolt 8 is inserted/driven into the screw hole 5 from the bolt hole 2 on the cylinder head 1 side, so that the cylinder head cover 3 is fastened/fixed to the cylinder head 1. Thereby, even if strength of the cylinder head cover 3 is low, a boss part 4 of the cylinder head cover 3 never becomes the seat surface. Furthermore, stress applied to the cylinder head cover 3 side is dispersed to screw threads of the screw hole 5, and is eased thereby.
