  • FIG. 3 is a view of the first member 12 and the second member 13 at this time in the negative direction of the Z axis.
  • the description of the housing 10 and the cover 11 is omitted in order to avoid complication of the drawing.
  • the first member 12 rotates counterclockwise.
  • An example of the state where the cover 11 is opened is shown in FIGS. 4 and 5. Note that in FIGS. 4 and 5, the description of the housing 10 and the cover 11 is omitted in order to avoid complication of the drawings.
  • the first member 12 rotates counterclockwise around the rotation axis AX with the protruding portion 122 engaged with the notch portion 133. Specifically, the first member 12 rotates around the rotation axis AX in a state where the first surface 133a and the second surface 133b are in contact with a continuous portion.
  • the cover 11 can be opened and closed only by the first member 12 and the second member 13.
  • the first member 12 and the second member 13 do not require a rod-shaped shaft member unlike a conventional hinge, and therefore have a simple structure.
  • the first member 12 and the second member 13 can be formed only by sheet metal processing, and the manufacturing process is simple because processing such as caulking and welding, which is required in the conventional manufacturing of hinges, is not required.
  • the second member 17 shown in FIGS. 9 and 10 includes a first member support portion 171 that supports the first member 12, and a rotation range limiting portion 172 that has a shape that limits the rotation range of the first member 12. ..
