<p>PROBLEM TO BE SOLVED: To provide a seal member, in which the trace of an illegal access is reliably left.SOLUTION: A seal member 1 fitted in a sealing hole having a sealing object place formed in a deep part, for sealing a sealing object place is constituted of: a cylindrical insertion part 11 to be inserted from the lower end side into the sealing hole; a cover part 12 arranged on the upper end side of the cylindrical insertion part 11 for covering the sealing hole; and a connection part 13 for connecting the upper end of the cylindrical insertion part 11 to the lower face of the cover part 12 only at a partial sectionαin the circumferential direction. The engaging part 11 for causing the outer peripheral part of the cylindrical insertion part 11 to engage with the inner circumferential part of the sealing hole is formed in the outer peripheral part of the cylindrical insertion part 11. The sectionα, in which the connection part 13 is formed, in the circumferential direction of the upper end of the cylindrical insertion part 11 is preferred to overlap a sectionβ, in which an engaging part 111 in the circumferential direction of the outer circumference of the cylindrical insertion part 11 is formed.</p> |
