The fan guard includes a guide portion having a tubular outer shape, which protrudes toward the fan. A center in a distal end shape, which is defined by a contour line of a distal end portion of the guide portion, matches with a rotation axis of the boss portion. A center in a root shape, which is defined by a contour line of a root portion of the guide portion, is shifted with respect to the rotation axis of the boss portion.
