Electronic apparatus and fixing structure

摘要

An insertion member provided with a male thread on the peripheral surface thereof is inserted through an opening of a receiving member. The insertion member is fastened by a fastening member provided with a female thread on the inner surface thereof. A first O-ring is provided between the insertion member and the fastening member, and a second O-ring is provided between the fastening member and the receiving member. When viewing each circular cross-section of the first and second O-rings along a surface parallel to a moving direction of the fastening member at the point of fastening the insertion member by rotating the fastening member, a first point of each circular cross-section is pressed against a surface perpendicular to the moving direction, and a position displaced from a second point opposite to the first point of each circular cross-section is pressed against an inclined surface inclined to the moving direction.

1. An electronic apparatus comprising:
a receiving member having an opening; an insertion member that is inserted through the opening and provided with a male thread on a peripheral surface thereof; a fastening member that is provided with a female thread on an inner surface thereof threadably engaged with the male thread, fixes the insertion member to the receiving member by engaging the female thread with the male thread, and covers the opening; and a first O-ring positioned between the insertion member and the fastening member and a second O-ring positioned between the fastening member and the receiving member, in a state in which the insertion member is fastened by the fastening member, wherein, when viewing each circular cross-section of the first and second O-rings along a surface parallel to a moving direction of the fastening member when fastening the insertion member by rotating the fastening member, a first point of each circular cross-section is pressed against a surface perpendicular to the moving direction, and a position displaced from a second point opposite to the first point of each circular cross-section is pressed against an inclined surface inclined to the moving direction.
