1. A head lifting lowering device, comprising:
a lifting lowering mechanism that moves a liquid ejecting head, which ejects a liquid, straight in a first direction in which the liquid ejecting head is lifted/lowered, wherein the lifting lowering mechanism includes a first rail and a second rail;
a frame that supports the lifting lowering mechanism; and
an adjusting member that moves the first rail relative to the frame in a second direction different from the first direction, wherein
the second direction is orthogonal to the first direction,
the first rail and the second rail are supported by the frame,
the first rail and the second rail each guide, in the first direction, a protrusion provided on the liquid ejecting head,
the second rail is fixed to the frame,
the first direction includes a component of a horizontal direction,
the first rail includes an upper wall and a lower wall that form a moving path on which the protrusion moves,
a first gap between the upper wall and the lower wall at a first end of the moving path is smaller than a second gap between the upper wall and the lower wall at a second end of the moving path,
first end of the moving path is opposite to the second end of the moving path, and
the second end of the moving path is adjacent to the second rail.
