Abstract
A joint structure includes: a plurality of holes open to opposing surfaces of two members that oppose to each other, the holes each being filled with a fluid or powder filler (U) in a state where the holes communicate with each other, such that the two members are relatively fixed by the filler. The holes of the two members each have an inner surface that is wider in cross-sectional direction at a location distant from openings of the holes than at a location close to the openings.
Claims20
A joint structure, comprising:
- a plurality of holes open to opposing surfaces of two frames that oppose each other, wherein
- each hole of the plurality of holes is filled with a filler in a state that the plurality of holes communicate with each other and the two frames are fixed by the filler,
- each hole of the plurality of holes has an inner surface that is wider in a cross-sectional direction at a location distant from an opening of the hole than at a location close to the opening,
- at least one frame of the two frames supports an optical system, and
- a direction of positioning of the optical system is a direction perpendicular to an optical axis that passes through the optical system.

An apparatus, comprising:
- two frames that oppose each other;
- and
- a plurality of holes open to opposing surfaces of the two frames, wherein
- each hole of the plurality of holes is filled with a filler in a state that the plurality of holes communicate with each other and the two frames are fixed by the filler,
- each hole of the plurality of holes has a retaining surface that faces opposite to the opposing surfaces, and
- in a case that force for separating the opposing surfaces from each other is applied between the two frames, a relative movement of the two frames is restricted by a contact between the filler and the retaining surfaces of the plurality of holes.
3 more elements
An apparatus, comprising:
- a first frame having a first surface;
- a second frame having a second surface, the first frame opposing the second frame such that the first surface opposes the first surface;
- and
- a plurality of holes open to the first surface and the second surface, wherein
- each hole of the plurality of holes is filled with a filler in a state that the plurality of holes communicate with each other and the first frame and the second frame are fixed by the filler, and
- each hole of the plurality of holes has an inner surface that is wider in a cross-sectional direction at a location distant from an opening of the hole than at a location close to the opening.
