PROBLEM TO BE SOLVED: To provide a compact boosting mechanism capable of converting an input load to a higher output load, a pressure device having the boosting mechanism and a press-in device.SOLUTION: A boosting mechanism 10 included in an assembly device 1 acting as a pressure device for use in compressing several return springs 107 of an assembly A is operated such that as an input load is applied to a holding part 42 acting as a point of effort to cause an operation lever 4 to be rotated one direction around a supporting shaft 41, a driven roller 45 acting as a supporting point is guided by an auxiliary cam surface 51 and a main cam surface 52, a movable member 3 is moved in a prescribed direction, i.e. in a vertical direction together with the supporting shaft 41 becoming an application point, and as the operation lever 4 is turned in one direction, a rotating amount of the operation lever 4, i.e. a rate of the moving amount of the movable member 3 in a prescribed direction in respect to a turning length around the supporting shaft 41 of the holding part 42 becomes low. |
