Head-mounted display

A head-mounted display, comprising:

• an annular mounting fixture;
• an image display device including at least an image light unit that generates image light and is capable of emitting the image light to one side in a first direction along the first direction, a deflection member that deflects the image light emitted from the image light unit to one side in a second direction, and a casing that covers the image light unit and the deflection member;
• a connection fixture that is a member that mounts the image display device to the annular mounting fixture, and extends in a third direction perpendicular to the first direction and the second direction;
• a first connection member that connects a portion of the annular mounting fixture on another side in the first direction in comparison to a center in the first direction and on another side in the second direction in comparison to a center in the second direction, and the connection fixture to each other;
• and
• a second connection member that connects the image display device and the connection fixture to each other, and at least rotatably supports the image display device with respect to the connection fixture in a state in which a specific rotational axis, which extends in the first direction and is disposed on the one side in the second direction in comparison to the image display device, is set as a supporting point,
• wherein the first connection member rotatably supports the connection fixture with respect to the annular mounting fixture with two or more rotational degrees of freedom,
• wherein the second connection member rotatably supports the image display device with respect to the connection fixture with two or more rotational degrees of freedom including the specific rotational axis,
• wherein the first connection member includes a first ball joint,
• wherein the first ball joint includes a first ball stud including a first rod section that extends from one side of the annular mounting fixture and the connection fixture, a first sphere section that is provided in a front end of the first rod section, and a first socket that is provided on another side of the annular mounting fixture and the connection fixture, and comes into contact with at least a part of the first sphere section to slidably support the first sphere section,
• wherein the second connection member includes a second ball joint, and
• wherein the second ball joint includes a second ball stud including a second rod section that extends from one side of the image display device and the connection fixture, a second sphere section that is provided in a front end of the second rod section, and a second socket that is provided on another side of the image display device and the connection fixture, and comes into contact with at least a part of the second sphere section to slidably support the second sphere section.
