<p>A driving module has: a tube-like or columnar body to be driven (4); a tube-like supporting body (5) which houses therein the body to be driven; plate spring members (6, 7) which elastically and movably hold the body to be driven in a fixed direction with respect to the supporting body; and a driving means (10) which drives the body to be driven against the resilience of the plate spring members. The spring constant of the plate spring member on the side where a force generated by the driving means operates is larger than that on the side where the force generated by the driving means operates with the body to be driven therebetween.</p> |
