1. A recording apparatus comprising:
a recording head that performs recording on a medium that is transported;
a carriage that has the recording head mounted thereon and is movable in a width direction intersecting a transport direction of the medium;
a guide member that extends in the width direction and guides the carriage; and
a gap adjustment unit that displaces the carriage in a first axis direction to change a gap between the recording head and a support surface, wherein
the gap adjustment unit has
a sliding member that moves in the width direction integrally with the carriage while the sliding member slides with respect to the guide member, and
a cam member that is interposed between the carriage and the sliding member and has a stepped portion in which a maintenance surface that maintains a position of the carriage in the first axis direction and an adjustment surface that changes the position of the carriage in the first axis direction are alternately arranged in the width direction,
the gap adjustment unit is configured such that the cam member slides in the width direction with respect to the carriage and the sliding member to change the gap,
the stepped portion includes, as the maintenance surface, a first maintenance surface that maintains a position of the carriage with respect to the sliding member at a first position, a second maintenance surface that maintains the position of the carriage with respect to the sliding member at a second position at which the gap is smaller than the gap at the first position, and a third maintenance surface that maintains the position of the carriage with respect to the sliding member at a third position at which the gap is smaller than the gap at the second position,
a height difference between the first position and the second position in the first axis direction is larger than a height difference between the second position and the third position in the first axis direction, wherein a height of the third maintenance surface is higher in the first axis direction than a height of the first maintenance surface,
the stepped portion includes, as the adjustment surface, a first adjustment surface that couples the first maintenance surface and the second maintenance surface and a second adjustment surface that couples the second maintenance surface and the third maintenance surface, and
an inclination angle of the first adjustment surface with respect to a horizontal plane is smaller than an inclination angle of the second adjustment surface with respect to the horizontal plane.
