  This paper is about the mechanical design of superconducting accelerator
magnets. First, we give a brief review of the basic concepts and terms. In the
following sections, we describe the particularities of the mechanical design of
different types of superconducting accelerator magnets: solenoids, cos-theta,
superferric, and toroids. Special attention is given to the pre-stress
principle, which aims to avoid the appearance of tensile stresses in the
superconducting coils. A case study on a compact superconducting cyclotron
summarizes the main steps and the guidelines that should be followed for a
proper mechanical design. Finally, we present some remarks on the measurement
techniques.
