1. Technical Field
The present invention relates to a force detection apparatus and a robot.
2. Related Art
For example, as a force detection apparatus that detects a force applied thereto, a force detection apparatus described in Patent Document 1 (JP-A-10-68665) is known. The force detection apparatus described in Patent Document 1 has an attachment plate, an attachment block, a measurement cell sandwiched between the plate and the block, and two preload screws that apply preloads to the measurement cell through the attachment plate and the attachment block. Further, in the force detection apparatus described in Patent Document 1, the two preload screws are arranged in the width direction of the apparatus side by side for reduction of the height of the apparatus.
However, in the force detection apparatus, the preload screws are arranged in the width direction of the apparatus side by side, and it is difficult to reduce the width of the apparatus.
