目的とする。However, in the above-described structure, the rubber packing 5, which is a waterproof and dustproof member, has a small thickness. Therefore, as the frequency of use increases, the damage and the degree of adhesion of the rubber packing 5 increase. There has been a problem that turning over occurs due to the decrease and lowers the reliability in waterproofing and dustproofing. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to provide a cassette lid device which can improve the reliability of waterproofing and dustproofing and can reliably implement it.

And when closing the cassette cover 2, the outer peripheral portion of the rubber packing 1 is to be in close contact along the VTR housing 3. Go
Fixed part and outer peripheral part where rubber packing 1 is fixed to cassette lid 2
Between the cassette lid 2 and the VTR housing 3
It has a slanting middle part. The entire circumference of the rubber gasket 1 The present embodiment is characterized in that fixed to the cassette cover 2, the Rukoto provided the thick portion 1a by the projecting portion, the outer peripheral portion
The thickness is approximately twice as large as the thickness of the intermediate portion . According to the structure of this embodiment, the outer periphery of the rubber packing 1
By larger than the thickness of the intermediate portion of the thickness of the part, it is possible to enhance the part strength and the adhesion of the rubber gasket 1, when the damage or curling of the rubber packing can be prevented Tomo
The thickness of the middle part of the rubber packing is
Good elasticity of rubber packing 1 compared to thicker case
Thus, the degree of adhesion is also improved. FIG. 3 shows a second embodiment of the present invention, in which a projection protrudes outward instead of upward to form a thick portion 1a. This also exhibits the same effect as that of the first embodiment.

ト蓋装置を提要できる。As is clear from the above description of the embodiment, in the present invention, the thickness of the outer peripheral portion of the rubber packing is set at the intermediate portion.
By making it thicker than it is, the elasticity of the rubber packing
Strength and adhesion can be increased while maintaining
It is possible to provide a cassette lid device that can prevent the rubber packing from being damaged or turned up, reliably waterproof and dustproof, and improve the reliability of the product.
