Since a mounting member 11 has a cylindrical surface 11h to be engaged with a cylindrical hole 4d, it is possible to position a mounting member 11 and a nut 4 by only engaging the cylindrical surface 11h with the cylindrical hole 4d. Accordingly, it is possible to easily perform an assembly. In addition, when a force is applied to the mounting member 11 from the guide groove 1e of the case 1 in the rotational direction of the nut 4, the force is partially applied to the cylindrical hole 4d. Therefore, it is possible to reduce a load applied to screws 12 that fix the mounting member 11, and to use thinner screws.

Also, a moment of inertia of the leg link is decreased to curtail a load applied to the leg of the user. The drive source and the battery are located at positions higher than the third joint, and when the user is in an upstanding position, a plane passing through the second joint lies between the drive source and the battery.

An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a supporting portion that supports the tube member. As the print head reciprocates in a width direction of a recording medium, the tube member flexes as the print head mounted on a carriage moves. The tube protruding from the print head is inclined at approximately 30 degrees with respect to a moving direction of the print head, toward the supporting portion. When the tube is pulled toward the supporting portion, resistance to the movement of the print head can be restricted. When the tube bends or curves between the supporting portion and the print head, the tube can be moved smoothly toward the supporting portion. Thus, when the print head reciprocates, the tube can flex smoothly and the resistance applied to the print head by the tube can be restricted, allowing proper ink supply to the print head.
