Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved lighter, and more particularly to an improved opening / closing mechanism of a lighter with a lid. 2. Description of the Related Art Generally, a gas lighter with a lid generally has a makeup case in which a gas tank and an ignition operation mechanism are housed. In this type of conventional lighter, a makeup tank has a gas tank and an ignition mechanism. A support substrate for supporting the operating mechanism,
It was general that a decorative case was screwed on after supporting various parts on it. However, in such a conventional lighter, various parts such as a gas tank are individually supported on the base, and the decorative case is screwed. Assembling requires a lot of labor, and it is difficult to automate the assembling, so that the assembly has to be done manually. Particularly, in the case of the opening / closing mechanism of the case lid which is capped at the upper end opening of the case, it takes a lot of time to attach such as positioning, and the case lid hangs in the opening direction or the closing direction. There was a problem. The present invention has been made in view of such a problem, and a click feeling at the time of opening and closing can be obtained to surely perform the opening and closing operation of the case lid, and the assembly is easy and the automation can be facilitated. Moreover, the purpose is to provide a lighter that can be manufactured at low cost. [0006] In order to solve the above problems and achieve the intended purpose, the structure which is the gist of the present invention is a bottomed cylindrical case having an upper opening. A lighter comprising a gas tank housed in the case, an ignition operation mechanism, a case lid capped at an upper end opening of the case, and a connecting member for connecting the case lid and the case so as to be openable and closable. The link member includes a case link stopper, a link whose one end is pivotally connected to the case link stopper by a pin, and a lid link stopper which is pivotally connected to the other end of the link by a pin. It is configured by a hinge, and the lid link stopper is inserted and connected to the case lid, and the case link stopper is sandwiched and fixed by the case and a pressing cap fixed in the case. Exists in the writer. Each of the case link stopper and the lid link stopper is provided with a pair of projecting pieces for pivotally supporting the link, and the tip of the link is inserted between the projecting pieces so that the pin is attached to the pin. It is good to pivot. Further, a pair of projecting portions are integrally formed on the step at one corner of the inner surface of the base portion of each projecting piece projecting on the case stopper, and the lower end of the link is inserted between the projecting portions. It is preferable that the link is sandwiched by and the upright state of the link is maintained. Furthermore, an inclined surface is provided on the upper end of the case link stopper, and an inclined surface parallel to the inclined surface is also provided on the lower surface of the corresponding lid link stopper, and both inclined surfaces are joined to each other. It is preferable to set the angle and the length of the link so that the case link stopper, the link and the lid link stopper are aligned in a straight line in this state.

In the upper opening 1A of the case 1, the gas tank 3, the operation cap 15, and the windshield cap 20 are prevented from coming off.
In addition, a hole 21B for leading out the operation portion 15A of the operation cap 15 and a window 21C for exposing the windshield cap 20 are provided, and a metal coating is applied to the inner surface of the operation cap 15 so as not to be melted by a flame. ing. On the other hand, the case 1 has a link type hinge 22 whose one end is sandwiched and fixed by the case 1 and the pressing cap 21.
Is installed. The link type hinge 22 is shown in FIGS.
As shown in the drawing, a case link stopper 23, a link 25 whose one end is pivotally connected to the case link stopper 23 by a pin 24, and a lid link stopper which is pivotally connected to the other end of the link 25 by a pin 26. And 27. The case link stopper 23 and the lid link stopper 27 are a pair of protrusions 23B, 23B and 27B for pivotally supporting the link 25, respectively.
27B is provided in a protruding manner, and both ends of the link 25 are inserted between the respective protruding pieces, and are pivotally attached to the pins 24 and 26. Further, each projecting piece 23 of the case link stopper 23
At one corner of the inner surface of the base portion of B, 23B, a protruding portion 23
C and 23C are integrally molded, and the protrusions 23C and 23C
The lower end 25A of the link 25 is sandwiched between them to be sandwiched, and the upright state of the link 25 is maintained. Further, the inclined surface 2 is provided on the upper end of the case link stopper 23.
3A is provided, and correspondingly, the lower surface of the lid link stopper 27 is also provided with an inclined surface 27A parallel to the inclined surface 23A, and as shown in FIG. 5, both inclined surfaces 23A, 27A are joined to each other. Case link stopper 23, link 2 in the state
The angle and the length of the link 25 are set so that the lid link stopper 5 and the lid link stopper 27 are arranged in a straight line. When the lid link stopper 27 is opened and closed, the corner portion 27C of the inclined surface 27A is the inclined surface 23A of the case link stopper 23. When the vehicle comes into contact with the vehicle and gets over the vehicle, a click feeling is obtained by the tension of the link 25 and the elasticity of the inclined surface 23A and the corner portion 27C, and it is urged toward either the opening direction or the closing direction. The case link stopper 23 is sandwiched between the case 1 and the presser cap 21, and the stepped portion 23D of the case link stopper 23 is pressed by the presser cap 21 so as to prevent the stopper from coming off. Further, a case lid 28, which covers the top of the case 1 and is opened and closed, is fixed to the lid link stopper 27 which is the other end of the link type hinge 22. That is, the case lid 28 is provided with a recess 28A into which the lid link stopper 27 is inserted.
The lid link stopper 27 is press-fitted and fixed therein. The lower surface of the case lid 28 is obliquely cut corresponding to the upper surface of the case 1. A spring piece 28B is provided on the inner surface of the case lid 28 along the lid link stopper 27 so that the corner portion 25B at the upper end of the link 25 elastically slides every time the lid 28 is opened and closed. This spring piece 28B contacts the rear surface of the upper end of the link 25 to regulate the angle of the lid 28 with respect to the link when the lid is closed so that the closed state is maintained. Further, a metallic protective plate 29 is attached to the inner surface of the lid 28 on the flame port 20C side to prevent the lid 28 from being deformed by the flame.
