1. An endoscope camera head comprising
a first member and a second member that are capable of rotating relative to each other about a first axis, wherein
the first member has a first rotation-sliding surface that extends in an annular shape about the first axis as a center, the first member having an outer diameter;
the first member includes a concave portion that extends in an annular shape about the first axis as a center,
the first rotation-sliding surface includes a continuous inner surface of the concave portion,
the second member is configured to engage with the first rotation-sliding surface in a state in which movement to a direction of the first axis is restricted relative to the first member, and has a second-rotation sliding surface that rotation-slides relatively to the first rotation-sliding surface about the first axis,
the second member includes a through hole having an inner diameter larger than the outer diameter of the first member, and
the second rotation-sliding surface abuts only on a first part of the first rotation-sliding surface, to expose a second part of the first rotation-sliding surface outside.
