A process of forming a predetermined shape by generally known blowing, a process of removing distortion by annealing, a process of cutting the opening end face with a bead cut, a process of polishing the cut end face, a process of heating the polished opening end face, and a process of heating the polished opening end face. It is manufactured through a process such as annealing the opening end face to remove distortion, but because it is formed into a predetermined shape by blowing, the dimensional accuracy is unstable and it is difficult to obtain a uniform product. Connecting part 5C
Since both ends of the curved surface are formed with relatively large radii R 1 and R 5 as shown in the enlarged view in Fig. 2,
The pressing part 6A of the glove holder 6 presses the connecting part 5C in a point contact state, causing the yellow glove 5 to wobble or being damaged due to concentration of the pressing force.

に設定される。 FIG. 3 is a sectional view showing an embodiment of the yellow glove according to the present invention. In the figure, the yellow glove 10 includes a bottomed cylindrical portion 10A with a hemispherical closed end, a large diameter cylindrical portion 10B with open ends at both ends and a bottomed cylindrical portion 10A having a larger outer diameter (inner diameter) than the bottomed cylindrical portion 10A. The open end and large diameter cylindrical part 10
It is integrally formed with a connecting portion 10C that connects the opening at one end of B. The connecting portion 10C is formed into a conical shape whose circumferential surface is inclined at the same angle Θ over the entire length, and both ends a and b are connected to the bottomed cylindrical portion 10.
A and the large-diameter cylindrical portion 10B at appropriate obtuse angles α 1 and α 2 (α 1 =α 2 ), respectively. However, both ends a and b are curved with a slight curvature due to unavoidable sag due to processing accuracy of the mold, moldability of the glass, etc. The inclination angle Θ is set to an appropriate angle within a range of about 20 to 70 degrees.

According to , when the connecting part 10C is pressed with the pressing part 6A of the globe holder 6 when assembled into the lamp body,
Since the inner surface of the pressing part 6A and the surface of the connecting part 10C are in surface contact, the yellow glove 10 can be securely fixed, preventing wobbling, and since there is no concentration of pressing force, damage to the yellow glove 10 itself can be avoided. Can be prevented.
次に、イエローグローブ１０の製造方法を第４
図に基づいて説明する。 Next, the method for manufacturing the yellow glove 10 will be described in a fourth manner.
This will be explained based on the diagram.
先ず第４図ａに示すように従来周知の廻し吹き

を有してイエローグローブ１０より長く形成され
る。 First, as shown in FIG. 4a, a bottomed cylindrical body 15 with one end open is manufactured by forming a lump of glass melted into a cylindrical shape using a well-known rotary blower. This bottomed cylindrical body 15 is a yellow globe 10
It is longer than the yellow glove 10 and has substantially the same outer and inner diameters as the bottomed cylindrical portion 10A.

されることになる。 Next, the bottomed cylindrical body 15 is inserted into the yellow globe forming hole 17 of the first mold 16 shown in FIG. 1B with the opening facing upward. The glove forming hole 17 is formed to have the same external shape as the yellow glove 10, so that the fitting hole 17A has substantially the same hole diameter and depth as the bottomed cylindrical portion 10A of the yellow glove 10, and this fitting hole A large-diameter forming hole 17B is provided on the open end side of the hole 17A and has a larger hole diameter than the hole 17A, and a large-diameter forming hole 17B is provided between the large-diameter forming hole 17B and the fitting hole 17 and has a circumferential surface extending over the entire length. It is comprised of a tapered hole 17C that is inclined at the same angle and whose both ends intersect with the fitting hole 17A and the large diameter portion forming hole 17B at obtuse angles α 1 and α 2 . Therefore, the bottomed cylindrical body 15 is fitted into the fitting hole 17A.

１６内に完全に圧入した状態を示す。 Next, the second mold 20 is press-fitted into the bottomed cylindrical body 15 fitted into the fitting hole 17A. This second mold 20 has an external shape similar to the globe forming hole 17 and is smaller by the plate thickness of the yellow globe 15, so that the opening side of the bottomed cylindrical portion 15 is expanded to form the large diameter portion. The large diameter cylindrical portion 10B and the connecting portion 10C of the yellow glove 10 are formed in close contact with the hole 17B and the tapered hole 17C. In this case, when the second mold 20 is press-fitted, the opening of the bottomed cylindrical body 15 is heated and melted by a heating means such as a heater (not shown) to a temperature at which plastic deformation is possible. Figure c shows the state in which the second mold 20 is completely press-fitted into the first mold 16.

As described above, in the yellow glove according to the present invention, the connecting part that connects the bottomed cylindrical part and the large diameter cylindrical part is formed in a conical shape that is inclined at the same angle over the entire length of the circumferential surface, and both ends are Since it is connected at an obtuse angle to the bottomed cylindrical part and the large diameter cylindrical part,
When assembling the lamp body, the globe holder can be pressed into contact with the connecting part in a surface contact state.
Damage to the yellow glove itself can be prevented due to the looseness of the yellow glove and the dispersion of the pressing force.

The opening of the bottomed cylinder is heated, and at the same time a second mold having the same shape as the inner shape of the yellow globe is press-fitted into the bottomed cylinder. Since the bottom cylindrical body is formed into a yellow globe shape using both molds, it is possible to manufacture yellow globes with high precision and uniform quality.
It is possible to reduce the defective rate.
