[0141] 1. First Embodiment: First to Fourth Viewpoints
[0142]
[0143] figure 1 is a perspective view showing the brake device according to the first embodiment of the present invention, figure 2 from another angle figure 1 Diagram of the braking device. Such as figure 1 , figure 2 As shown, the brake device BD of this embodiment is formed by connecting the motion converting portion DT and the resistance applying portion RA in the front-rear direction. Here, if figure 1 As shown, the direction from the resistance applying part RA to the motion conversion part DT is defined as the front-rear direction, and the left-right direction (width direction) and the up-down direction are determined based on the front-rear direction. However, the above-mentioned direction is a direction used for convenience in this specification, and does not mean that the use state of the brake device is in the above-mentioned direction.
[0144] The motion converter DT includes a base 70 fo...

[0212] 2. Second Embodiment: First to Fourth Viewpoints
[0213] Next, according to Figure 11 to Figure 31 A braking device 1000 according to a second embodiment of the present invention will be described. The braking device 1000 according to the second embodiment is the same as the braking device BD of the first embodiment in that it brakes the movement of the rope, but there is a difference in its configuration. Specifically, in the brake device BD according to the first embodiment, the motion conversion part DT and the resistance applying part RA are provided on a substantially horizontal plane, but in the brake device 1000 according to the second embodiment, the equivalent motion conversion The mechanism of the portion DT differs from the mechanism corresponding to the resistance applying portion RA in that it is provided at a substantially vertical position. Here, the motion conversion part DT is equipped with the clamping body which catches the movement of a rope. Fu...

[0324] 3. The third embodiment: the first point of view and the second point of view
[0325] Next, according to Figure 32 to Figure 37 The braking device 4000 according to the third embodiment will be described. Such as Figure 32 As shown, the braking device 4000 of the present embodiment is configured such that the motion conversion part DT and the resistance applying part RA are connected through the shaft core 31 . Hereinafter, the outline of this embodiment will be described.
[0326] First of all, about the motion transformation part DT, such as Figure 32 , Figure 33 as well as Figure 34 As shown in each figure of (b), the pair of clamping members of the clamping body is constituted by the tension transmission roller 30 and the inclined portion 441 formed on the fixing member 440 . That is, in the present embodiment, only one of the holding members is configured to be movable. Additionally, if Figure 32 and Figure 34 As shown, the rotation of the tension ...
