In the direction of protruding from the packing, a neck part having a diameter smaller than the inner diameter of the through hole, a locking part having a diameter larger than the inner diameter of the through hole, and a tension part having a diameter smaller than the neck part and longer than the depth of the through hole. And are formed in a line in order.

[Action]

According to the above configuration, the mounting leg to be inserted into the through hole provided in the instrument body is integrally projectingly provided on the surface of the packing facing the instrument body, and the mounting leg has the neck portion, the locking portion, and the tension portion. Since the locking portion is provided as described above, the fixing strength of the packing to the instrument body can be increased by making the locking portion larger in diameter than the inner diameter of the through hole. By making the tensile portion longer than the depth of the through hole, it is possible to easily insert the mounting leg into the through hole by pulling the tensile portion when the mounting leg is inserted into the through hole. That is, since the mounting leg is integrally formed with the packing from an elastic material, pulling the pulling portion extends the locking portion and reduces the diameter of the locking portion. It is easy to insert. As a result, it is possible to easily insert the mounting leg into the insertion hole by the pulling portion while securing a sufficient strength for fixing the packing to the instrument body by the locking portion.

【Example】

As shown in FIG. 1, an instrument main body 1 having a light source (not shown) such as a straight tube fluorescent lamp disposed on the front surface is formed in a flat plate shape. Further, a glove 2 formed in a semi-cylindrical shape from a translucent material such as glass or synthetic resin is attached to the front surface of the instrument body 1. The globe 2 is formed in a shape in which a dividing surface that divides the cylinder in half is opened, and the globe 2 is attached to the instrument body 1 so as to close the opening. Grooves 2a are formed on both sides of the globe 2. The groove 2a of the glove 2 is engaged with the protrusion 3a provided on the holding frame 3, and the holding frame 3 is fixed to the device body 1 by screwing the mounting screw 4 onto the device body 1 through the holding frame 3. Further, the peripheral portion of the globe 2 is clamped between the instrument body 1 and the holding frame 3, so that the globe 2 is fixed to the instrument body 1. By the way, a packing 5 made of an elastic material such as silicone rubber or EPT rubber is sandwiched between the instrument body 1 and the opening edge of the glove 2 so as to buffer or drip between the instrument body 1 and the glove 2. Has been done. As shown in FIG. 2, the packing 5 is integrally provided with a plurality of mounting legs 6 on the surface facing the instrument body 1. The mounting leg 6 is inserted into a through hole 7 formed in the instrument body 1 as shown in FIG. 1 (b), and as shown in FIG. 3, it is a neck in the protruding direction from the packing 5. The portion 6a, the locking portion 6b, and the pulling portion 6c are formed in a lined up order. The neck portion 6a has a through hole 7
The inner diameter of the engaging portion 6b is smaller than the inner diameter of the through hole 7, and the engaging portion 6b is formed larger than the inner diameter of the through hole 7. Also, the tension part 6c is the neck part
The diameter is smaller than 6a. Here, there are various shapes of the locking portion 6b, for example, an abacus ball shape as shown in FIG. 3 (a), a spherical shape as shown in FIG. 3 (b), and a shape shown in FIG. 3 (c).
There is a shape in which peaks and valleys are continuous on the peripheral surface as shown in FIG. The pulling portion 6c is formed to be longer than the depth of the through hole 7, and when the mounting leg 6 is inserted into the through hole 7, the engaging portion 6c is a locking portion.
A part of the tensile portion 6c is pulled out from the through hole 7 in a state where the 6b is not introduced into the through hole 7. According to the above configuration, when the attachment leg 6 is inserted into the through hole 7, the pulling portion 6c protruding from the through hole 7 is pulled as shown in FIG. The outer diameter of the locking portion 6b is drawn into the through hole 7 in a state where the outer diameter of the locking portion 6b is small, and if the tension portion 6c is strongly pulled while the packing 5 is in close contact with the surface of the instrument body 1, the tension portion 6c is locked. It can be shredded from section 6b. At this time, the locking part
As 6b swells, neck 6a contracts and packing 5
Will be more closely attached to the instrument body 1. In this way, by providing the pulling portion 6c, the locking portion 6b is formed in the through hole 7
Is more easily introduced into the through hole 7, and the outer diameter of the locking portion 6b can be made sufficiently larger than the inner diameter of the through hole 7,
The fixing strength of the packing 5 to the instrument body 1 can be increased. That is, the fixing strength, the ease of assembly and the dilemma are eliminated. The above description is for the case where the instrument body 1 is thick, but when the instrument body 1 is thin, as shown in FIG.
Passes through the through hole 7 and protrudes to the back side of the instrument body 1,
The packing 5 is fixed to the device body 1 with the device body 1 being sandwiched between the packing 5 and the locking portion 6b.
