Abstract
Realized is a sealing member which exhibits excellent sealing properties even at a low temperature and a high pressure. A sealing member (100) includes: a first pressing part (110) that presses a first side part of a gap by pressing from a lateral direction; a second pressing part (120) that is pressed against a second side part of the gap by the pressing from the lateral direction; and a part (122) that induces deformation of the sealing member (100) such that the sealing member (100) is strained toward the second side part by the pressing from the lateral direction.
Claims14
A sealing member which seals a gap, of which a first end is an opening and a second end is a contact part and in which a direction from the first end to the second end is a depth direction, by coming into close contact with both side parts and the contact part of the gap in a case where the sealing member is disposed in the gap and pressed in the depth direction from a first end side, the sealing member comprising:
- a first pressing part that is disposed on a first end side of the sealing member and that presses a first side part of the gap in a case where the sealing member is pressed in the depth direction of the gap in a state of sealing with the sealing member;
- a second pressing part that is disposed on a second end side of the sealing member and that comes into close contact with the contact part and presses a second side part of the gap by pressing with respect to the first pressing part in the state of sealing with the sealing member;
- a connection part that is a part in which a second end part of the first pressing part and a first end part of the second pressing part are overlapped and joined, and that makes the cross-sectional shape constricted in a central part of the sealing member;
- and
- a deformation inducing part that strains the sealing member in a direction in which the second pressing part is directed to the second side part of the gap, by the pressing with respect to the first pressing part in the state of sealing with the sealing member.
A sealing mechanism which is configured such that a sealing member is disposed in a gap, of which a first end is an opening and a second end is a contact part and in which a direction from the first end to the second end is a depth direction, so as to seal the gap by coming into close contact with both side parts and the contact part of the gap in a case where the sealing member is pressed in the depth direction from a first end side, wherein:
- the sealing member includes
- a first pressing part that is disposed on a first end side of the sealing member and that presses a first side part of the gap in a case where the sealing member is pressed in the depth direction of the gap in a state of sealing with the sealing member,
- a second pressing part that is disposed on a second end side of the sealing member and that comes into close contact with the contact part and presses a second side part of the gap by pressing with respect to the first pressing part in the state of sealing with the sealing member,
- a connection part that is a part in which a second end part of the first pressing part and a first end part of the second pressing part are overlapped and joined, and that makes the cross-sectional shape constricted in a central part of the sealing member, and
- a deformation inducing part that strains the sealing member in a direction in which the second pressing part is directed to the second side part of the gap, by the pressing with respect to the first pressing part in the state of sealing with the sealing member;
- the first pressing part is apart from the second side part of the gap, and the second pressing part is apart from the first side part of the gap;
- and
- the sealing member seals the gap in a state where the second pressing part is strained toward the second side part of the gap, by being pressed in the depth direction from the first end side so that the first pressing part moves to the second end side and the second pressing part comes into contact with the contact part.
