2. The housing according to claim 1 , wherein
a diameter of the head of the screw is larger than the opening of the second member.
3. The housing according to claim 1 , wherein
the first member is in contact with the second member in a direction in which the fastener screw is pulled out from the hole.
4. The housing according to claim 1 , wherein
a portion of the second member is thickened to form a thick portion rising to surround the prong.
5. The housing according to claim 1 , further comprising
a first fixing screw that fixes the first member and the second member to each other.
6. The housing according to claim 5 , wherein
the hinge bracket includes a first shaft extending along one side of the first member, and
the first fixing screw fixes the first member and the second member to each other at a position outward of the fastener screw in an axial direction of the first shaft.
7. The housing according to claim 6 , further comprising
at least one second fixing screw that fixes the first member and the hinge bracket to each other.
8. The housing according to claim 7 , wherein
a plurality of the second fixing screws are provided for the fastener screw, and arranged at positions outward and inward of the fastener screw in the axial direction of the first shaft.
9. The housing according to claim 6 , wherein
a plurality of the fastener screws are provided along the axial direction of the first shaft, and
the housing further comprises a third fixing screw which fixes the first member and the second member to each other at a position between the fastener screws located at both axial ends of the first shaft.
10. The housing according to claim 9 , wherein
the plurality of the fastener screws are provided along the axial direction of the first shaft.
11. The housing according to claim 1 , wherein
the hinge bracket includes
a first shaft extending in a direction along one side of the first member, and
a second shaft extending in a direction different from the first shaft.
12. The housing according to claim 1 , wherein
the first member and the second member are made of metal.
13. The housing according to claim 1 , wherein
the first member and the second member are provided with coatings different from each other.
14. An electronic device, comprising:
a housing including
a first member that includes a plurality of prongs, each of the plurality of prongs having a hole and projecting in a thickness direction of the first member from a surface of the first member,
a second member with a plurality of openings, each of the plurality of prongs being inserted into each of the plurality of openings,
a width of attachment of the second member being tapered from a position of each of the plurality of openings toward a center position between positions of the plurality of openings, the width of attachment being a size of a vertical direction of a line linking the plurality of openings, and
a plurality of fastener screws, each of the plurality of fastener screws being screwed into an opening of each of a plurality of hinge brackets and the hole of each of the plurality of prongs to fasten the first member and the second member and the hinge bracket, the second member being located between the hinge bracket and the first member, a head of each of the plurality of fastener screws pressing each of the plurality of hinge brackets and further each of the plurality of pressed hinge brackets pressing both of the top of each of the plurality of prongs and the surface of the second member,
a hinge which has the hinge bracket, and
