Abstract
A cylindrical body includes a cylindrical member, made by forming a metal plate into a cylindrical shape such that the two end faces of the metal plate face each other, and a nonmetallic adhesive member bonding the two end faces together. The two end faces each include an adhesive part, and the adhesive member is disposed between the adhesive parts of the end faces. The adhesive part of one end face is not parallel to the adhesive part of the other end face. Each end face also includes a contact part which is in contact with the contact part of the other end face.
Claims21
A cylindrical body comprising:
- a cylindrical member made by forming a metal plate, the metal plate having a first end face, a second end face, a third end face, and a fourth end face, into a cylindrical shape such that the first end face and the second end face of the metal plate face each other;
- a nonmetallic first adhesive member bonding the first end face to the second end face;
- and
- a second adhesive member, wherein
- the first adhesive member is disposed between a first part of the first end face and a second part of the second end face, and the first part and the second part are not parallel to each other, and
- the first adhesive member is bonded to a portion of an inner peripheral surface of the cylindrical member,
- the third end face and the fourth end face are in an axial direction of the cylindrical member,
- a distance between the third end face and the fourth end face is greater than an outside diameter of the cylindrical member,
- the second adhesive member is bonded to a third part away from the first part of the first end face and a fourth part away from the second part of the second end face in the cylindrical member,
- the second adhesive member of the third part and the second adhesive member of the fourth part are not continuous with each other,
- the second adhesive member of the third party is disposed away from the third end face, and
- the second adhesive member of the fourth part is disposed away from the fourth end face.
