Abstract
A securing device is disclosed in which a cylindrical member having a male thread provided on the outside circumferential surface and to which an adhesive is applied is screw-engaged in the tapped hole of another member from the entrance of the hole so that the cylindrical member is secured in a prescribed position inside the other member, wherein the inside diameter of the female thread of the tapped hole is made larger in the portion of the female member from the entrance of the hole to the prescribed position than in the prescribed position of the female member.
Claims2
A securing device in which a cylindrical male member having a first thread provided on the outside circumferential surface of said male member and to which an adhesive is applied is screw-engaged into a second thread in a tapped hole of a female member from the entrance of said hole so that said cylindrical male member is secured in a prescribed position inside said female member, wherein said second thread has a series of thread turns having a larger equal inner diameter in the portion of said female member from the entrance of said hole to said prescribed position than in the prescribed position having inner thread turns of a smaller diameter.
A securing device comprising:
- a cylindrical male member having a first thread provided on the outside circumferential surface of said male member;
- adhesive applied to said first thread;
- and
- a female member having a tapped hole into which said cylindrical male member is screw-engaged;
- wherein said tapped hole has a second thread projecting inwardly, and wherein a series of thread turns of said second thread from the entrance of said hole to a prescribed position along the axis of said hole are equally truncated so that said series of thread turns have the same inner diameter, and
- wherein a remainder of thread turns of said second thread starting at said prescribed position have a smaller inner diameter than said series of thread turns.
