The base includes a contact portion that is disposed at a position behind the support unit in a moving direction and above the upper end of the wheel, and with which the moving tool comes into contact when the support unit is bent rearward. ## Claims ### Claim 1 An apparatus equipped with a moving tool, the apparatus comprising: a base; and the moving tool including a wheel that rolls on a floor surface during movement of the apparatus and a support unit that is fixed to the base at a position above an upper end of the wheel and that supports the wheel, wherein the base includes a contact portion that is disposed at a position behind the support unit in a moving direction and above the upper end of the wheel, and with which the moving tool comes into contact when the support unit is bent rearward. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein in the moving direction, the contact portion is disposed behind a rotational center line of the wheel during the movement. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein in the moving direction, the contact portion is disposed behind a midpoint in the moving direction between the rotational center line of the wheel and a rear end of the wheel in the moving direction during the movement. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein the contact portion is disposed in front of a rear end of the wheel in the moving direction. during the movement. ### Claim 5 (depends on 2) The apparatus according to claim 2, wherein the contact portion is disposed in front of a rear end of the wheel in the moving direction during the movement. ### Claim 6 (depends on 3) The apparatus according to claim 3, wherein the contact portion is disposed in front of a rear end of the wheel in the moving direction during the movement. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 8 (depends on 2) The apparatus according to claim 2, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 9 (depends on 3) The apparatus according to claim 3, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 10 (depends on 4) The apparatus according to claim 4, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 11 (depends on 5) The apparatus according to claim 5, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 12 (depends on 6) The apparatus according to claim 6, wherein the support unit is fixed to the base at a position above the contact portion. ### Claim 13 (depends on 1) The apparatus according to claim 1, wherein in the moving direction, a center point in the moving direction of a region in which the support unit is fixed to the base is in front of a midpoint in the moving direction between a rotational center line of the wheel and a front end of the wheel in the moving direction during the movement. ### Claim 14 (depends on 2) The apparatus according to claim 2, wherein in the moving direction, a center point in the moving direction of a region in which the support unit is fixed to the base is in front of a midpoint in the moving direction between the rotational center line of the wheel and a front end of the wheel in the moving direction during the movement. ### Claim 15 (depends on 13) The apparatus according to claim 13, wherein the center point of the support unit is disposed behind the front end of the wheel in the moving direction during the movement. ### Claim 16 (depends on 1) The apparatus according to claim 1, wherein the contact portion is disposed at a position such that the moving tool comes into contact with the contact portion while the support unit is within an elastic deformation range. ### Claim 17 (depends on 1) The apparatus according to claim 1, wherein the contact portion is disposed at a position such that an angle between a first line and a second line is 10 degrees or less, the first line connecting the contact portion and a center point of deformation of the support unit in the moving direction when the support unit is bent rearward, the center point being provided on a fixed portion of the support unit that is fixed to the base, and the second line connecting the center point and a portion of the wheel that comes into contact with the contact portion. ### Claim 18 (depends on 1) The apparatus according to claim 1, wherein the moving tool further includes a cover disposed between the wheel and the contact portion, and wherein the contact portion is disposed at a position such that an angle difference obtained by subtracting a second angle from a first angle is 10 degrees or less, the first angle being an angle between a first line and a second line before deformation of the support unit, the first line connecting the contact portion and a center point of deformation of the support unit in the moving direction when the support unit is bent rearward, the center point being provided on a fixed portion of the support unit that is fixed to the base, the second line connecting the center point and a portion of the wheel that comes into contact with the contact portion with the cover disposed therebetween, and the second angle being an angle between the first line and the second line when the support unit is bent rearward and when the cover is disposed between the contact portion and the wheel and in contact with both the contact portion and the wheel. ### Claim 19 (depends on 1) The apparatus according to claim 1, wherein the moving tool is one of a plurality of moving tools arranged with intervals therebetween, and the contact portion is positioned to correspond to at least one of the plurality of moving tools that is disposed in a front region in the moving direction. ### Claim 20 (depends on 19) The apparatus according to claim 19, wherein at least one of the plurality of moving tools is a front moving tool that is disposed in the front region in the moving direction for movement in two directions that cross each other, and the contact portion is positioned to correspond to the movement in both of the two directions of the front moving tool.
