  An object of the present invention is to provide a rotating mechanism that can extract rotational force without using petroleum or the like and without adversely affecting the environment.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a rotating mechanism having a pressed rotating wheel, a pressing rotating wheel, and a pressing force applying mechanism, and the pressed rotating wheel is A core-like rotating member that can rotate around a center axis that is fixed in position, and a base end portion thereof is fixed directly or indirectly to the core-like rotating member, and from the base end portion toward the tip end portion. The core-shaped rotating member is formed so as to be directed in the centrifugal direction and toward the circumferential direction of the core-shaped rotating member, and a surface connecting the tip portions forms a substantially cylindrical outer cylindrical surface. A plurality of pressing force transmission members formed of an elastic body, and the pressing rotary wheel is rotatable about a central axis that is not fixed to its own position, Part of the surface is in contact with part of the outer cylindrical surface of the pressed rotating wheel A shall, said pressing force application mechanism is based on the force of gravity, it is to urge the central axis of the press rotating wheel toward the pressed rotary wheel, a rotating mechanism.

In the rotating mechanism according to the present invention, the pressing force applying mechanism presses the outer peripheral surface of the pressing rotating wheel against the outer cylindrical surface of the pressed rotating wheel (the pressing force transmitting member of the portion) based on gravity. The central axis of the rotating wheel is biased toward the pressed rotating wheel.
The urging force is transmitted to the outer peripheral surface of the pressing rotary wheel, and the outer peripheral surface (of which the portion that comes into contact with the pressed rotating wheel) is a pressing force transmission member of the pressed rotating wheel (that contacts the pressing rotary wheel). Press.
Here, each pressing force transmitting member is directed in the centrifugal direction of the core-shaped rotating member from the base end portion toward the tip end portion thereof, and one circumferential direction (counterclockwise or clockwise) of the core-shaped rotating member. It is formed to go to. That is, each pressing force transmission member is directed from the tip end portion toward the base end portion in the other circumferential direction (clockwise or counterclockwise) of the core rotation member, and the centripetal point of the core rotation member. It is formed to go in the direction.
For this reason, the pressing force is transmitted along the pressing force transmitting member (the one that abuts the pressing rotating wheel), and the proximal end portion of the pressing force transmitting member is the other circumference of the core rotating member. Press in a direction with a direction (clockwise or counterclockwise) component.
For this reason, the core-shaped rotating member rotates based on the pressing force.

For this reason, when the central axis of the pressing rotating wheel is urged toward the pressed rotating wheel by the pressing force applying mechanism, the urging force is transmitted to the pressing force transmitting member (pressed rotating member) via the core-shaped rotating member. (The contact of the wheel follows the reverse path of the pressed rotating wheel), and the pressing force transmitting member is a pressing force transmitting member (pressing force of the pressed rotating wheel). The one that makes contact with the rotating wheel). Thus, the pressing force transmission member of the pressed rotating wheel is smoothly pressed based on the urging force with respect to the central axis of the pressing rotating wheel.

  In the rotating mechanism of the present invention, the pressing force transmitting member of the pressing rotating wheel is also formed of an elastic body. Therefore, the rotating member is urged by the pressing force applying mechanism and presses the pressed pressure rotating wheel, and elastically deforms by its reaction. . Then, when the pressing force transmission member attempts to restore the original shape elastically, the pressing force is transmitted smoothly, and the above-described effects can be obtained more reliably.

[Embodiment 1]
Next, an embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the rotating mechanism includes a pressed rotating wheel 100, a pressing rotating wheel 200, and a pressing force applying mechanism 300.

As shown in FIGS. 1 and 2, the pressed rotating wheel 100 has a cylindrical rotating member 120 (core-shaped rotating member). A shaft support portion 122 is provided inside the cylindrical rotating member 120. A shaft 124 is inserted into the shaft support portion 122 so as to be relatively rotatable. The shaft 124 extends horizontally along the central axis of the pressed rotating wheel 100.
As shown in FIG. 1, the shaft 124 is supported by a pair of support members 150. Both supporting members 150 are fixedly provided.
Thus, the pressed rotating wheel 100 is rotatable about the shaft 124 (the central axis of the pressed rotating wheel 100).

As shown in FIGS. 1 and 2, a large number of pressing force transmission members 130 (base ends thereof) are fixed to the outside of the cylindrical rotating member 120 at equal angular intervals as follows. All the pressing force transmission members 130 have the same structure.
There is a gap between the pressing force transmission members 130.

As shown in FIGS. 1 to 3, a large number of support pieces 128 are fixed to the cylindrical rotating member 120 (the outer peripheral surface thereof) at equiangular intervals.
The base end portion of each pressing force transmission member 130 is fixed to the cylindrical rotating member 120 (the outer peripheral surface thereof) and each support piece 128.

The pressing force transmission member 130 has an arcuate shape, and as a whole, from the proximal end portion toward the distal end portion thereof, is directed to the centrifugal direction of the cylindrical rotating member 120, and the circumferential direction of the cylindrical rotating member 120 ( 1 circumferential direction) (counterclockwise direction in FIGS. 1 to 3).
On the contrary, if it demonstrates along the direction which goes to the base end part from the front-end | tip part of the pressing force transmission member 130, each pressing force transmission member 130 will go to the centripetal direction (direction which goes to the center axis line of the cylindrical rotation member 120). It is going diagonally so that it may go in the clockwise direction in FIGS.
Thus, with respect to each pressing force transmission member 130, the base end portion of the pressing force transmission member 130 is more in the direction around the axis of the cylindrical rotating member 120 (based on the central axis (axis 124) of the cylindrical rotating member 120). Angle) advances in the clockwise direction in FIGS.

  Each pressing force transmission member 130 is formed of an elastic body. For example, it is made of a springy metal or synthetic resin. In other words, a force is generated that is elastically deformed by being pressed and elastically returns to its original shape.

  All the pressing force transmission members 130 are collectively referred to as a pressing force transmission member group 135. The front end surface of the pressing force transmission member group 135 (the surface connecting the front ends of all the pressing force transmission members 130) has a substantially cylindrical shape. This is called the outer cylindrical surface 136.

  As shown in FIG. 1, at least the tip portion of each pressing force transmission member 130 and the vicinity thereof (the respective edge portions in the circumferential direction of the pressing force transmission member group 135) are formed in a zigzag shape. .

Further, as described above, the outer cylindrical surface 136, that is, the front end surface of the pressing force transmission member group 135 (the surface connecting the front ends of all the pressing force transmission members 130) is substantially cylindrical. To be exact, it is as follows.
That is, as shown in FIG. 3, a portion on the opposite side of the circumferential direction (counterclockwise direction in FIG. 3) of the cylindrical rotating member 120 in the tip portion of each pressing force transmission member 130 (in FIG. 3). The portion in the clockwise direction is recessed toward the central axis (axis 124) of the pressed rotating wheel 100 (cylindrical rotating member 120).
Therefore, a portion on the side in one circumferential direction (counterclockwise direction in FIG. 3) and a portion on the opposite side (portion in the clockwise direction in FIG. 3) of the tip portions of adjacent pressing force transmission members 130 ) Has a step.

As will be described later, the pressed rotating wheel 100 (the corresponding pressing force transmitting member 130 in the pressing force transmitting member group 135) is pressed by the other member (the pressing rotating wheel 200) by the pressed rotating wheel 100 (cylindrical rotating member). 120) when pressed toward the center axis (axis 124).
That is, the pressed pressing force transmission member 130 is elastically bent in the pressing direction, and the circumferential direction of the cylindrical rotating member 120 in the tip portion of the pressing force transmission member 130 (counterclockwise in FIG. 3). And the tip of the pressing force transmission member 130 adjacent to the circumferential direction (counterclockwise direction in FIG. 3) side of the cylindrical rotating member 120 with respect to the pressing force transmission member 130 as a reference. Among them, the portion on the opposite side to the circumferential direction (counterclockwise direction in FIG. 3) of the cylindrical rotating member 120 is substantially flush.

  As shown in FIGS. 1 and 2, the pressing rotating wheel 200 has a structure that is substantially the same as the pressed rotating wheel 100. About each element of the press rotary wheel 200, the code | symbol which added "100" to the code | symbol of each element of the corresponding pressed rotary wheel 100 is attached | subjected, and the detailed description is abbreviate | omitted suitably.

  The pressing rotating wheel 200 has a cylindrical rotating member 220 (core-shaped rotating member), and a shaft support portion 222 is provided on the inside thereof, and the shaft 224 is inserted into the shaft support portion 222 so as to be relatively rotatable. Has been.

A large number of pressing force transmission members 230 are provided outside the cylindrical rotating member 220.
All the pressing force transmission members 230 have the same structure. There is a gap between the pressing force transmission members 230.
All the pressing force transmission members 230 are collectively referred to as a pressing force transmission member group 235. The front end surface of the pressing force transmission member group 235 (the surface connecting the front ends of all the pressing force transmission members 230) has a substantially cylindrical shape, which is referred to as an outer cylindrical surface 236.

As a whole, the pressing force transmission member 230 is directed in the centrifugal direction of the cylindrical rotating member 220 from the proximal end portion toward the distal end portion thereof, and in one circumferential direction (one circumferential direction) of the cylindrical rotating member 220. It is formed so as to face (clockwise direction in FIGS. 1 and 2).
On the contrary, if it demonstrates along the direction which goes to the base end part from the front-end | tip part of the pressing force transmission member 230, each pressing force transmission member 230 will go to the centripetal direction (direction which goes to the center axis line of the cylindrical rotation member 220). It is heading diagonally to go counterclockwise.
Thus, with respect to each pressing force transmission member 230, the base end portion of the pressing force transmission member 230 is more in the direction around the axis of the cylindrical rotating member 220 (based on the central axis (axis 224) of the cylindrical rotating member 220). Angle) proceeds in the counterclockwise direction in FIGS.

  That is, in the pressed rotating wheel 100, the pressing force transmitting member 130 is directed in the circumferential direction of the cylindrical rotating member 120 from the base end portion toward the distal end portion (counterclockwise direction in FIGS. 1 and 2). In the pressing rotating wheel 200, the pressing force transmitting member 230 is opposite to the direction (in the clockwise direction in FIGS. 1 and 2) toward the one circumferential direction of the cylindrical rotating member 220 from the base end portion toward the tip end portion. Direction.

Of the outer cylindrical surface 236 of the pressing rotary wheel 200, a portion (the front end portion of the pressing force transmitting member 230) of the shaft 224 (the central axis of the pressing rotary wheel 200) and the pressed rotary wheel 100 A portion of the outer cylindrical surface 136 that is substantially the same height as the shaft 124 (the central axis of the pressed rotating wheel 100) (the tip portion of the pressing force transmitting member 130) is in contact with the shaft 124.
The pressed rotary wheel 100 and the pressed rotary wheel 200 are in such a positional relationship.

As shown in FIG. 1, the pressing force application mechanism 300 includes a support portion 312, a pair of bar members 314, and a weight 316.
The support portion 312 is fixedly provided below the pressing rotary wheel 200, and the base end portion of the bar 314 is rotatably connected to the support portion 312.
The pair of bar members 314 is directed substantially vertically upward from the base end portion toward the tip end portion.
A weight 316 is connected to the distal ends of the pair of bar members 314 via a rope 318. That is, the base end portion of the rope 318 is connected to the connecting member 315 of the bar 314, and the rope 318 extends substantially horizontally in the direction from the pressing rotating wheel 200 toward the pressed rotating wheel 100. The portion is supported by a pulley 319 and a weight 316 is connected to the tip of the rope 318.

  The shaft 224 described above is rotatably provided in the middle length portion of the pair of bar members 314. The direction from the base end portion to the shaft 224 at least between the base end portion and the shaft 224 of the bar 314 is a direction away from the pressed rotating wheel 100 as it goes upward (more precisely, the pressed rotation). It is slightly inclined from the vertical so as to go from the shaft 124 of the wheel 100 toward the shaft 224 of the pressing rotary wheel 200.

  Thus, the pressing force applying mechanism 300 (the bar 314) moves the shaft 224 (center axis) of the pressing rotating wheel 200 toward the pressed rotating wheel 100 in a substantially horizontal direction (precisely, based on the gravity applied to the weight 316). The shaft 224 is urged in a direction gradually going upward as it goes from the shaft 224 to the shaft 124.

Next, the effect of this rotating mechanism will be described.
As shown in FIGS. 1 and 2, the pressing force applying mechanism 300 urges the shaft 224 of the pressing rotating wheel 200 in the substantially horizontal direction toward the pressed rotating wheel 100, and the urging force is applied to the cylindrical rotating member 220. Then, the pressure is transmitted along the pressing force transmission member 230 (that contacts the pressed rotating wheel 100).
Then, the pressing force transmission member 230 makes the front end portion of the pressing force transmission member 130 of the pressed rotating wheel 100 (which contacts the pressing rotating wheel 200) substantially in the horizontal direction (the central axis (axis 124 of the cylindrical rotating member 120)). ) In the direction toward).

  Accordingly, the pressing force is transmitted along the pressing force transmitting member 130 (in FIG. 1 and FIG. 2, the cylindrical rotating member 120 moves in the clockwise direction from the distal end portion toward the proximal end portion). The cylindrical rotating member 120 rotates in the clockwise direction in FIGS. 1 and 2 based on the pressing force. Thus, the pressed rotating wheel 100 rotates in the clockwise direction in FIGS.

As the pressed rotating wheel 100 rotates as described above, the pressing rotating wheel 200 also rotates counterclockwise in FIGS. 1 and 2, and the pressing force transmitting member 230 (FIG. 1) next to the pressing rotating wheel 200. 2 and the pressing force transmitting member 230 adjacent in the clockwise direction in FIG. 2 is the pressing force transmitting member 130 (the pressing force transmitting member 130 adjacent in the counterclockwise direction in FIGS. 1 and 2). ).
That is, in the pressed rotating wheel 100 and the pressed rotating wheel 200, the pressing force application to the adjacent pressing force transmitting members 130 and 230 is transferred.
Based on this, the pressed rotating wheel 100 and the pressing rotating wheel 200 rotate in the same manner as described above.

  By repeating the above, the pressed rotating wheel 100 (cylindrical rotating member 120) continues to rotate in the clockwise direction in FIGS. Thereby, the rotational force can be taken out.

A part of the above-described operation will be described in more detail as follows.
As described above, the pressing force transmission member 130 of the pressed rotating wheel 100 is formed of an elastic body.
For this reason, as shown in FIG. 3, the pressing force transmitting member 130 of the pressed rotating wheel 100 is pressed by the distal end portion of the pressing force transmitting member 130 of the pressed rotating wheel 100, so that the pressing force transmitting member 130 is elastic. Deforms. Then, the pressing force transmission member 130 elastically attempts to return to the original shape, thereby directly pressing the cylindrical rotating member 120 and indirectly connecting the cylindrical rotating member 120 via the support piece 128. Press. Then, the cylindrical rotating member 120 rotates smoothly as described above.

  Further, since each pressing force transmission member 230 of the pressing rotary wheel 200 is also formed of an elastic body, although not shown in detail, the pressing force (attachment) is reversed in the opposite direction before the above-described operation. Power) is transmitted. That is, the urging force applied to the shaft 224 by the pressing force applying mechanism 300 is transmitted to the distal end portion of the pressing force transmission member 230 via a path opposite to the above-described direction, and the pressing force transmission member 230 is transmitted to the pressing force transmission member. 130 is smoothly pressed.

Further, as described above, as shown in FIG. 3, the pressing force transmission member 130 of the pressed rotating wheel 100 is elastically deformed. At this time, as described above, each pressing force transmission member 130 is deformed. A portion (a portion on the clockwise direction in FIG. 3) opposite to one circumferential direction (counterclockwise direction in FIG. 3) of the cylindrical rotating member 120 at the tip of the rotating member 100 is a pressed rotating wheel 100. It is recessed toward the central axis (axis 124) of the (cylindrical rotating member 120). Then, when the pressing force transmission member 130 is elastically deformed as described above, one circumferential direction (counterclockwise direction in FIG. 3) of the cylindrical rotating member 120 in the tip portion of the pressing force transmission member 130. ) Side and the tip of the pressing force transmission member 130 adjacent to the circumferential direction (counterclockwise direction in FIG. 3) side of the cylindrical rotating member 120 with reference to the pressing force transmission member 130 A portion of the cylindrical rotating member 120 opposite to one circumferential direction (counterclockwise direction in FIG. 3) is substantially flush.
For this reason, with the rotation of the pressed rotating wheel 100, it is possible to smoothly transfer the response to the pressing rotating wheel 200 from the pressing force transmitting member 130 to the next pressing force transmitting member 130.
The same applies to the pressing rotary wheel 200 (detailed illustration thereof is omitted).

In addition, at least the front end portion of each pressing force transmission member 130 and the vicinity thereof (the respective edge portions in the circumferential direction of the pressing force transmission member group 135) are formed in a zigzag shape. It is possible to smoothly deliver the response to the pressing rotary wheel 200.
The same applies to the pressing rotary wheel 200.

[Embodiment 2]
Next, a second embodiment of the present invention will be described based on FIG. 4 with a focus on differences from the first embodiment. Common elements are denoted by the same reference numerals and description thereof is omitted as appropriate. The same applies to the following.

  In the rotation mechanism of this embodiment, with respect to one pressed rotating wheel 100, a pair of pressing rotating wheels 200 (first pressing rotating wheel 200a, second pressing rotating wheel 200b) and a pair of pressing force applying mechanisms 300 (first A first pressing force applying mechanism 300a and a second pressing force applying mechanism 300b) are provided. Both the pressed rotating wheels 200a and 200b are disposed with the pressed rotating wheel 100 interposed therebetween.

  The first pressing rotating wheel 200a and the first pressing force applying mechanism 300a correspond to the pressing rotating wheel 200 and the pressing force applying mechanism 300 of the embodiment. The reference numerals of the elements of the first pressing force applying mechanism 300a are indicated by adding “a” to the end of the reference numerals of the elements of the pressing force applying mechanism 300 in the first embodiment.

The second pressing rotary wheel 200b has the same structure as the first pressing rotary wheel 200a.
The second pressing force applying mechanism 300b has a support portion 312b, a pair of bar members 314b, and a weight 316b.

That is, the base end portion of the rope 318b is connected to the distal end portion of the bar 314b (the connecting member (not shown) corresponding to the connecting member 315 in FIG. 1), and the rope 318b is connected to the pressed rotating wheel from the pressing rotating wheel 200b. The rope 318b extends diagonally so as to go to 100 and upward, and a length portion of the rope 318b is supported by a pulley 319b, and a weight 316b is connected to the tip of the rope 318b.

The shaft 224 described above is rotatably provided in the midway length portion of the pair of bar members 314b. The direction from the base end portion to the shaft 224 between at least the base end portion of the bar 314b and the shaft 224 is a direction away from the pressed rotating wheel 100 as it goes downward (to be precise, the pressed rotation). It is slightly inclined from the vertical so as to go from the shaft 124 of the wheel 100 toward the shaft 224 of the pressing rotary wheel 200.
About others, it is the same as that of the 1st pressing force provision mechanism 300a.

In this rotating mechanism, as in the case of the first embodiment, the first pressing rotary wheel 200a (almost the same height as the shaft 224 of the outer cylindrical surface 236) based on the urging force of the first pressing force applying mechanism 300a. ) Presses the pressed rotating wheel 100 (the portion of the outer cylindrical surface 136 that is substantially the same height as the shaft 124), and the second pressing rotating wheel 200b based on the urging force of the second pressure applying mechanism 300b. (A portion of the outer cylindrical surface 236 having the same height as the shaft 224) presses the pressed rotating wheel 100 (a portion of the outer cylindrical surface 136 having the same height as the shaft 124).
The pressing force by the first pressing rotating wheel 200a and the pressing force by the second pressing rotating wheel 200b are superimposed in the direction of rotating the pressed rotating wheel 100 and are horizontal with respect to the shaft 124 of the pressed rotating wheel 100. The amount added in the direction is offset, and the pressed rotating wheel 100 rotates more smoothly.

[Embodiment 3]
Next, a third embodiment of the present invention will be described based on FIG. 5 with a focus on differences from the first embodiment.
The rotating mechanism includes a pressed rotating wheel 110, a pressing rotating wheel 210, and a pressing force applying mechanism (not shown).

The pressing rotary wheel 210 has substantially the same structure as the pressing rotary wheel 200 of the rotation mechanism of the first embodiment. As with the pressed rotating wheel 110, the pressing force transmission members 230 are also connected by a chain 240 (chain). The chain 240 is also at least substantially stretched (not so slack).

For this reason, in this rotating mechanism, the following specific operational effects can be obtained.
As described in the first embodiment, the pressed rotary wheel 110 (the pressing force transmission member 130) presses the pressing rotary wheel 210 (the pressing force transmission member 230). A pressing force is transmitted from the transmission member 130 to the cylindrical rotating member 120.
At that time, in the first embodiment, the pressing force is transmitted to the cylindrical rotating member 120 only by the pressing force transmitting member 130 that contacts the pressing rotating wheel 200 (the corresponding pressing force transmitting member 230 among them). However, in the rotation mechanism of the third embodiment, since the pressing force transmission members 130 are connected to each other by the chain 140, the pressing force transmitted to the pressing force transmission member 130 in contact with the pressing rotary wheel 210 is the chain 140. Thus, the pressure is also transmitted to the other pressing force transmitting members 130, and the pressing force is dispersed and transmitted to the cylindrical rotating member 120 through the plurality of pressing force transmitting members 130.
Therefore, compared to the case where the pressing force is transmitted to the cylindrical rotating member 120 through only one pressing force transmitting member 130, the force applied between each pressing force transmitting member 130 and the cylindrical rotating member 120 is less. It is made small, the strength burden of the part is reduced, and durability is improved.
The same applies to the pressing rotary wheel 210.

[Embodiment 4]
Next, a fourth embodiment of the present invention will be described based on FIG. 6 with a focus on differences from the first embodiment.
In this embodiment, the pressing rotary wheel 400 does not have a plurality of pressing force transmission members (130) as in the first embodiment, but has a simple cylindrical shape.
A shaft support portion 422 is provided inside the press rotating wheel 400, and a shaft 424 is inserted into the shaft support portion 422 so as to be relatively rotatable.
The pressing rotary wheel 400 is positioned above the pressed rotating wheel 100, and the pressing rotating wheel 400 (the lower end portion thereof) and the pressed rotating wheel 100 (the upper end portion thereof) are in contact with each other.

The pressing force applying mechanism 500 includes a support portion 512, a pair of bar members 514, and a weight 516.
The support portion 512 is provided in a fixed position obliquely below the pressing rotary wheel 400, and the base end portions of the pair of bar members 514 are rotatably connected to the support portion 512.
The pair of bar members 514 extend obliquely from the base end part toward the direction approaching the pressed rotating wheel 100 in the horizontal direction and upward, and a weight 516 is provided at the tip part.
The shaft 424 described above is rotatably provided in the middle length portion of the pair of bar members 514.
In this way, the pressing force applying mechanism 500 (the bar 514) presses the shaft 424 (center axis) of the pressing rotating wheel 400 substantially vertically downward toward the pressed rotating wheel 100 based on the gravity applied to the weight 516.

Then, the pressing rotary wheel 400 applies a vertical downward pressing force to the distal end portion of the pressing force transmitting member 130 of the pressed rotating wheel 100 (which contacts the pressing rotary wheel 400).
Thereby, the pressing force is transmitted along the pressing force transmitting member 130 (in FIG. 6, the cylindrical rotating member 120 moves in the clockwise direction from the distal end portion toward the proximal end portion), and the cylindrical rotating member 120 rotates in the clockwise direction in FIG. 6 based on the pressing force. Thus, the pressed rotating wheel 100 rotates in the clockwise direction in FIG.
At the same time, the pressing rotary wheel 400 rotates counterclockwise in FIG.

  Also in the above-described case, the pressing force transmission member 130 is formed of an elastic body, and is elastically deformed by the pressing by the pressing rotary wheel 400, and smoothly moves to the cylindrical rotating member 120 by the force to restore the elasticity. The pressing force is transmitted, and the cylindrical rotating member 120 (the pressed rotating wheel 100) rotates smoothly.

[Embodiment 5]
Next, a fifth embodiment of the present invention will be described with reference to FIGS. The fifth embodiment is obtained by modifying only a part of the first embodiment, and the difference from the first embodiment will be mainly described.

This rotating mechanism includes a pressed rotating wheel 101, a pressing rotating wheel 201, and a pressing force applying mechanism 300.
The pressed rotating wheel 101 has substantially the same structure as the pressed rotating wheel 100 of the rotation mechanism of the first embodiment.
The pressed rotating wheel 101 has a cylindrical rotating member 120 (core-shaped rotating member). A shaft 124 is inserted in a relatively rotatable manner with respect to a shaft support portion 122 provided inside the cylindrical rotating member 120.

A large number of pressing force transmission members 131 are fixed to the outside of the cylindrical rotating member 120 at equal angular intervals.
Most of the pressing force transmission members 131 are formed thinner than the pressing force transmission members 130 of the first embodiment. That is, the circumferential length (thickness) of the pressed rotating wheel 101 is short (thin). For this reason, there is a larger gap between the adjacent pressing force transmission members 131 than in the first embodiment.
The tip of each pressing force transmission member 131 is formed in the same manner as each pressing force transmission member 130 of the first embodiment. For this reason, the clearance gap between the front-end | tip parts of each adjacent pressing force transmission member 131 is made small like the case of Embodiment 1. FIG.
The above is realized because each pressing force transmission member 131 is formed of an elastic body such as metal and has inherently high strength, so that a predetermined strength is ensured even if it is thin. To get.
By doing so, the pressed rotary wheel 101 can be reduced in weight, and the pressed rotary wheel 101 can rotate more smoothly.

The same can be said for the pressing rotary wheel 201.
That is, most of the pressing force transmission members 231 (other than the tip portion) of the pressing rotary wheel 201 are formed thin.
And the same effect as the pressed rotating wheel 101 is obtained.

It should be noted that the above is only a few embodiments of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.
For example, the aspect which combined the characteristic peculiar to each embodiment arbitrarily may be sufficient.
