1. A positioning structure configured to position a liquid jet head to a head installation part of a liquid jet recording device, the positioning structure comprising:
a protruding part provided to one of the head installation part and the liquid jet head; and
a positioning mechanism which is provided to another of the head installation part and the liquid jet head, and which is configured to adjust a position of the head installation part in a direction along an installation surface thereof with respect to the protruding part, wherein
the positioning mechanism includes:
a contact member configured to have contact with the protruding part; and
a displacement mechanism configured to displace the contact member along a displacement axis extending in an oblique direction crossing a direction perpendicular to the installation surface, and
one of contact parts of the protruding part and the contact member is formed to have a curved surface shape taking a first intersecting axis crossing the installation surface as a central axis, and another of the contact parts is formed to have a curved surface shape taking a second intersecting axis as a central axis, the second intersecting axis crossing an imaginary plane including the displacement axis and a vertical axis extending in a direction perpendicular to the installation surface, and the second intersecting axis being nonparallel to the first intersecting axis.
