Document Type and Number:
Japanese Patent JP3738332
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a bolt from being removed by an unauthorized person by forming a restraining section on the opposing side where the hinge section of a main body is provided and also forming a section to be restrained on the opposing side where the hinge section of a cover body is provided.
SOLUTION: A sealing device 1 of a bolt consists of a cylindrical main body 4 where a bolt through hole 3 is opened on a bottom plate 2 and a cover body 5 which closes the top opening port of the main body 4. The device 1 is integrally molded of a synthetic resin. The cover body 5 is connected to the top surface of the main body 4 through a hinge section 6. On the opposing side where the hinge section 6 of the main body 4 is formed, a restraining section 7 is formed and a section to be restrained 8 is formed on the opposing side of the hinge section 6 of the cover body 5. The restraining section 7 consists of plural pins 7b which are formed on a projected section 7a of the top surface of the main body 4. A tip 7c of the pin 7b is formed in an arrowhead shape. The section to be restrained 8 consists of plural holes 8b which are formed on a projected section 8a. The pins 7b are inserted into the holes 8b. When the pins 7b are inserted into the holes 8b, the cover body 5 cannot be pulled out by the jaws of the arrowheads of the tips 7c. Therefore, the bolt can not be removed without breaking the sealing device 1.
