A glass substrate includes a first major surface, a second major surface, an end surface, a first boundary surface, a second boundary surface, and a bent portion in which the first major surface is bent so as to be concave and the second major surface is bent so as to be convex. The bent portion includes a portion in which a distance Dfrom the end surface to the first major surface in a tangential direction, extending from the end surface toward the first major surface, of the glass substrate is longer than a distance Dfrom the end surface to the second major surface in a tangential direction, extending from the end surface toward the second major surface, of the glass substrate. A difference between the distance Dand the distance Dis 50 μm or larger.

A first payload computation value which represents a weight of loads loaded on the work implement in a first attitude is obtained. The first attitude and a second attitude are equal to each other in ratio between a horizontal distance from a position of a center of gravity of a first link member to a base end of the first link member and a horizontal distance from a position of the center of gravity of the loads loaded on the work implement to the base end. A second payload computation value which represents a weight of loads loaded on the work implement in the second attitude is obtained. When the first payload computation value and the second payload computation value are determined as being different from each other, a weight of a second link member is changed and processing above is repeated.
