Force sensor assembly
First Claim
1. A force sensor assembly comprising:
- a force sensor;
a first support member;
a threaded portion provided for the force sensor;
an opening made in the first support member;
a nut screwed onto the threaded portion which is inserted through the opening;
a restricting member provided between the force sensor and the nut; and
a spacer, which is deformable in a direction of thickness thereof, provided between the force sensor and the nut, a shape of the spacer being adapted to avoid interference with the restricting member;
wherein before the nut is tightened onto the threaded portion, a summation of thickness for the first support member and the spacer is adapted to be not less than a height of the restricting member, and the nut is tightened up with a predetermined fastening torque until the spacer deforms so that the nut strikes the restricting member.

Abstract
A force sensor assembly includes a force sensor, a first support member, a threaded portion, an opening made in the first support member, a nut, a restricting member and a spacer. The nut is screwed onto the threaded portion which is inserted through the opening. The restricting member is provided between the force sensor and the nut. The spacer, which is provided between the force sensor and the nut, is deformable in a direction of its thickness. The shape of the spacer is adapted to avoid interference with the restricting member. Before the nut is tightened onto the threaded portion, a summation of thickness for the first support member and the spacer is adapted to be not less than a height of the restricting member. The nut is tightened up with a predetermined fastening torque until the spacer deforms so that the nut strikes the restricting member.
