         [0022]     In this embodiment, the number of all the gravity pressurizing devices  3  is four; each gravity pressurizing device  3  includes an axle rod  31  and a restraining and pressing portion  33 , the restraining and pressing portion  33  includes a roller  32  and a plurality of restraining and pressing rods  331 , the restraining and pressing rods  331  are combined on a lateral surface of the roller  32  and are arranged in a circle. One end of the axle rod  31  is connected to a power inputting device  34  to drive the gravity pressurizing device  3  to roll on the base  2 ; the power inputting device  34  is provided above the center of the base  2 , it can be a motor or some other transmitting mechanism with the same power inputting function. The other end of the axle rod  31  is connected to the roller  32 ; the roller  32  is preferably a metallic gear to be attracted by gravity to generate downward pressing action. The protruding teeth circling the periphery of the roller  32  function as a second engaging portion  321  to be engaged with the first engaging portion  21  of the base  2  for positioning. The first and the second engaging portions  21 ,  321  can be in the shape of umbrellas.  
         [0023]     In this embodiment, the number of all the moving-to-and-fro linking members  4  is four, but it can be multiple in practical application, the moving-to-and-fro linking member  4  are used cooperatively and respectively with the restraining and pressing portions  33  of the gravity pressurizing devices  3 . Each of the moving-to-and-fro linking members  4  includes a moving-to- and-fro slide member  41 , a gear  42 , an elastic member  43  and a power outputting portion  44 ; the slide member  41  is an elongate rod, it is restrained in a guiding way  451  to move to and fro in the latter. The upper portion of the slide member  41  is a push- pressing portion  411 , while the lower portion of the slide member  41  is a rack  412 ; the rack  412  is engaged with the gear  42 , the lower end of the rack  412  is connected with the elastic member  43  which is a spring; the gear  42  is connected with the power outputting portion  44 .  
         [0024]     Referring to  FIGS. 2 and 3  which are schematic views showing the state of use of the first embodiment of the present invention, when the power inputting device  34  drives one end of the axle rod  31  to rotate on the base  2 , the other end of the axle rod  31  moves the roller  32  to roll on the base  2 , the restraining and pressing rods  331  on a lateral surface of the roller  32  presses down the push-pressing portion  411  on the upper end of the slide member  41  of the moving-to-and-fro linking member  4 ; The moving-to-and-fro linking member  4  links up the gear  42  via the rack  412 , the gear  42  in turn links up the power outputting portion  44  to output power. At this time, the elastic member  43  on the lower end of the rack  412  is in a compressed state.  
         [0025]     When the roller  32  goes on to roll on the base  2 , the push-pressing portion  411  on the upper end of the slide member  41  gets rid of the pressing of a pressing rod  331 , so that the slide member  41  can restore its original position by a restoration force of the elastic member  43 .  
         [0026]     When the roller  32  rolls on the upper disc surface of the base  2 , the first engaging portion  21  on the periphery of the base  2  is engaged with the second engaging portion  321  on the periphery of the roller  32  for positioning, thus a pressing rod  331  can surely press or release the push-pressing portion  411  on the upper end of the slide member  41  without the situation of inability of alignment by accumulation of errors.  
         [0027]     Referring to  FIG. 4 , in practical application of the present invention, the periphery of the roller  32  can also be a smooth surface, one end of the power inputting device  34  is provided with a gear  341  in the shape of an umbrella, while one end of the axle rod  31  is provided with a gear  311  also in the shape of an umbrella, the two gears  341 ,  311  in the shape of umbrellas can be engaged with each other to control the rolling rate of the roller  32  on the on the upper disc surface of the base  2 .  
         [0028]     Referring to  FIG. 5 , each pressing rod  331  on a restraining and pressing portion  33  of the present invention can be provided with a first magnetic member  332 , while the push-pressing portion  411  on the upper end of the slide member  41  of the moving-to-and-fro linking member  4  can also be provided with a second magnetic member  413 ; the first and the second magnetic members  332 ,  413  are magnets of identical polarity, thereby a repelling action force between them can reduce the friction force between the pressing rod  331  and the push-pressing portion  411 .  
         [0029]     And referring to  FIG. 6 , one end of the restraining and pressing portions  33  of the present invention can also be added with a fixed plate  5  in the shape of a round disc, one side face of the fixed plate  5  can be connected with a plurality of restraining and pressing rods  331  to thereby increase the strength of the restraining and pressing rods  331  to be not subjected to deformation by a reaction from the push-pressing portion  411  of the slide member  41 .  
         [0030]     Referring to  FIG. 7 , the moving-to-and-fro linking member  4  can also be substituted by another structure different from any of the above stated to get the same function of transmitting. Wherein a moving-to-and-fro linking member  6  includes a moving- to-and-fro slide rod  61 , a link  62 , a crank axle  63  and a power outputting portion  64 ; the slide rod  61  is an elongate rod, it is restrained in a guiding way  651  provided in a fixed member  65  to move to and fro in the latter. The lower portion of the slide rod  61  is pivotally connected with an end of the link  62 , while the other end of the link  62  is connected with the crank axle  63  that is connected with the power outputting portion  64 .  
         [0031]     When the upper end of the slide rod.  61  is pressed by a restraining and pressing rod  331 , the link  62  is moved downwards to link up with the crank axle  63 ; then power outputting portion  64  outputs power. When the restraining and pressing rod  331  releases a push-pressing portion  611  on the upper end of the slide rod  61 , the crank axle  63  can go on rotating by the inertia effect provided during rotating of the crank axle  63 ; thereby power can be continuously output.  
         [0032]     Referring to  FIGS. 7-9  showing a schematic view of a second embodiment of the power generating device  1  of the present invention, wherein the moving-to-and-fro linking member  6  ( 8 ) further includes an upper linking plate  92  and a lower linking rod  93 , two ends of the upper linking plate  92  are pivotally connected respectively to the base  2  and the lower linking rod  93 , while the lower end of the lower linking rod  93  is pivotally connected to the push-pressing portion  411  ( 611 ); the upper linking plate  92  has an elevation angle to the base  2 . When the roller  32  rolls on the upper disc surface of the base  2 , by the heavy pressure exerted on the base  2  by the roller  32 , the upper linking plate  92  pushes the lower linking rod  93  and the push-pressing portions  411  and  611  downwards to thereby move the moving-to-and-fro linking members  6 ,  8  to output power.  
         [0033]     Referring to  FIG. 9  showing a schematic view of a third embodiment of the power generating device  1  of the present invention, wherein a gravity pressuring device  7  is preferably a metallic round disc, the periphery of the bottom surface of the round disc  7  has a plurality of magnetic down protruding parts  71  arranged in a circle, the down protruding parts  71  are used as a restraining and pressing portion. A push-pressing portion  811  of a slide member  81  on a moving-to-and-fro linking member  8  is provided thereon with a magnetic up protruding part  812 , the down protruding parts and the up protruding part  71 ,  812  are magnets of the same polarity. The gravity pressuring device  7  and a base  9  are provided therebetween with a plurality of rollers  91  to reduce the friction force between the gravity pressuring device  7  and the base  9  during rolling. Therefore, when the gravity pressuring device  7  is rotated on the base  9 , the down protruding parts and the up protruding part  71 ,  812  push the push-pressing portion  811  downwards by the repelling action force generated by the identical polarities; and by linking up of the moving-to-and-fro linking member  8 , the above stated effect of power outputting can also be obtained.  
         [0034]     Therefore, the present invention has the following advantages: 
    1. The present invention needs only to be input with a small power to make a gravity pressurizing device with a larger weight rotated on a base, and it can obtain a power output larger than the small power input through a mechanical linking up action induced by pressing on a moving-to-and-fro linking member under the gravity of the earth.     2. The present invention is structurally simple, it is not limited concerning regional natural resources when in use, and can be widely applied to save consumption of natural resources.    
 
         [0037]     In conclusion, according to the description disclosed above, the present invention surely can get the expected object thereof to provide a power generating device applicable completely to the regions all over the world to generate stable power output; therefore it has a high industrial value, what I claim as new and desire to be secured by Letters Patent of the United States is.
