Abstract
A torque detection device includes a first portion, a second portion disposed inside the first portion, and a connecting portion configured to link the first portion and the second portion. The first portion includes a first convex portion that projects toward the second portion. The second portion includes a second convex portion that projects toward the first portion. An inner surface of the first portion and a surface of the first convex portion link to the connecting portion. An outer surface of the second portion and a surface of the second convex portion link to the connecting portion. When torque is applied, the connecting portion deforms, and the first portion and the second portion are displaced relative to each other.
