In FIG. 4, the lower reciprocating guide portion 51r, the front lower lower guide portion 52r, the lower restoration guide portion 53r, and the rear lower lower guide portion 52r are seamlessly connected to form the lower guide portion 50r.
The rear moving member 10r is guided by the lower reciprocating guide 51r so as to be reciprocally movable in the front-rear direction.
When the rear moving member 10r reciprocates in the front-rear direction, a sliding frictional force is generated in the rear moving member 10r.
When the rear moving member 10r moves forward beyond the lower reciprocating guide portion 51r, it is guided by the front lower lower guide portion 52r and moved downward. Further, when the rear moving member 10r moves rearward beyond the lower reciprocating guide portion 51r, it is guided by the rear lower lower guide portion 52r and moved downward.
When the rear moving member 10r moves downward, the rear upper base 20r is lowered, and the object 1 supported by the upper base 20 is inclined rearward.

FIG. 6 is a second operation diagram of the object support mechanism according to the first embodiment of the present invention. FIG. 7 is a third operation diagram of the object support mechanism according to the first embodiment of the present invention.

When an earthquake occurs and the object is shaken horizontally, the undercarriage 40 is shaken in the front-rear and left-right directions, and acceleration acts on the object. The upper base 20 reciprocates only in the front-rear direction based on the lower base 40.
The front moving member 10f and the rear moving member 10r reciprocate back and forth while being guided by the lower guide portions 50f and 50r.
When the front moving member 10f and the rear moving member 10r are guided in the front-rear direction of the lower guide portions 50f, 50r and reciprocate, the thrust bearing 16 guides the traveling resistance due to the acceleration in the left-right direction with less travel resistance. The wheels 12 of the moving member 10f and the rear moving member 10r are rolled by the lower reciprocating guide portions 51f and 51r. When the wheel 12 rolls, a frictional force is generated between the fixed shaft 11 and the sliding member 15, and the lateral vibration of an object such as a laminated iron plate that is vibrated by an earthquake is attenuated.
Further, when the lower reciprocating guide portions 51f and 51r are recessed downward, a restoring force is generated toward the lowest recessed portion, and the front moving member 10f and the rear moving member 10r are located above the lower reciprocating guide portion 51r. To reciprocate back and forth.
When the rear moving member 10r moves forward beyond the front end of the lower reciprocating guide 51r, the rear moving member 10r is guided by the front lower guide 52r and moves downward. Further, when the rear moving member 10r moves forward beyond the rear end of the lower reciprocating guide portion 51r, the rear moving member 10r is guided by the rear lower lower guide portion 52r and moves downward.
The rear of the upper base 20 is tilted downward from the front.
The laminated iron plate 1 is supported by the back support structure 30 on the back surface.

By appropriately selecting the shape of the lower reciprocating guide 51r, it is possible to adjust the attenuation characteristics of lateral vibration when an earthquake occurs.
In general, the horizontal force is a combined force of a component force due to gravity and a sliding friction force, or a combined force of a component force due to gravity and a rolling friction force.

  When the lower reciprocating guide portion 51r is a contact surface that is linearly inclined upward in the front-rear direction from the central portion and has a circular arc shape in the front-rear direction of the central portion, The horizontal force is. When the rear moving member moves back and forth in the central portion, the horizontal force increases as it moves forward or backward.

  When the lower reciprocating guide portion 51r is a contact surface having an arc shape with the center portion facing downward, the value of the horizontal force increases as the rear moving member moves forward or backward.

  When the lower reciprocating guide portion 51r is a contact surface that is inclined linearly upward from the central portion in the front-rear direction, the value of the horizontal force is constant when the rear moving member moves.

  When the lower reciprocating guide portion 51r has a circular arc shape with the central portion facing downward, and a contact surface inclined linearly before and after the central portion, the horizontal force is forward when the rear moving member moves in the central portion. Alternatively, it increases as it moves rearward, and the horizontal force value is constant when moving forward or rearward of the central portion.

When the earthquake continues, energy from acceleration is continuously accumulated in the object. The accumulated vibration energy is consumed by the work of horizontal force. Therefore, the amplitude of the vibration in the front-rear direction of the object is difficult to be amplified.
When a large earthquake occurs, the object tilts backward, so that the object is less likely to fall forward.
In addition, the object is stable because it is inclined backward and the back surface is supported by the back surface support member.

After the earthquake has stopped, the fork claw 5 of the forklift is inserted under the upper frame 21 and the fork claw 5 is lifted.
When the fork claw 5 is inserted below the upper base 20 and lifted, the rear moving member 10r that supports the upper base 20 is lifted, and the lower restoration guide portion 53r contacts the rear moving member 10r from above. Since the lower restoration guide part 53r is recessed upward, the rear moving member 10r moves to the highest position of the lower restoration guide part 53r.
When the fork claw 5 is lowered, the rear moving member 10r contacts the lower reciprocating guide 51r. Therefore, the support surface of the upper base is restored to the original.

The shaft body moves in the front-rear direction without hitting the edge of the long hole.
When the shaking due to the earthquake continues, the function of the lower guide part 50f causes the rear of the upper base to go down and the object tilts.

FIG. 16 shows a state where the upper base is lifted by the fork claws 5.
After the shaking of the earthquake has stopped, the fork claw 5 of the forklift is inserted under the upper frame 21 and the fork claw 5 is lifted.
When the fork claw 5 is inserted below the upper base 20 and lifted, the edge of the long hole 61 fixed to the upper base 20 comes into contact with the shaft body 60. When the edge of the long hole 61 is recessed, the shaft body 60 moves to the highest position of the edge of the long hole 61.
When the fork claw 5 is lowered, the rear moving member 10r contacts the lower reciprocating guide 51r. Therefore, the support surface of the upper base is restored to the original.

If the object support mechanism according to the above-described first to fourth embodiments is used, the following effects are exhibited.
The object support mechanism that supports the object is provided with a back support structure that supports the back of the object, and when the acceleration due to the earthquake acting on the object exceeds a predetermined magnitude, the support structure is tilted backward. Therefore, if there is a big earthquake, the object will lean against the back support member and the object will be stabilized.
In addition, the support structure is composed of an upper frame and a lower frame, and a lower plan that guides the upper frame downward when the upper frame moves beyond the reciprocating guide and a reciprocating guide that guides the lower frame in the front-rear direction. Since the interior is provided, if there is an acceleration such as an earthquake, the upper platform is guided back and forth by the reciprocating guide, and if the longitudinal movement due to the acceleration increases, the rear of the upper platform lowers downward and the object is stable To do.
In addition, the front part of the upper base is supported by the front support structure, the rear part of the upper base is supported by the rear support structure, and the rear support structure is configured by the rear moving member, the rear upper base, and the rear lower base. The lower guide part provided on the rear guide member guides the rear moving member that supports the rear upper frame, and the lower reciprocating guide part guides the rear moving member in the front-rear direction. Since the rear moving member is guided downward, if the longitudinal movement due to acceleration is increased, the rear of the upper base is lowered downward, and the object is stabilized. Also, the lower reciprocating guide part is in contact with the rear moving member from below. Since the lower lower guide part is a contact surface that seamlessly connects to the rear reciprocating guide part and tilts downward, if the longitudinal movement due to acceleration increases, the rear of the upper base smoothly falls downward and the object is stabilized .
In addition, since the lower reciprocating guide portion has a contact surface recessed downward, when the rear moving member is guided to move back and forth by the lower reciprocating guide portion, a restoring force toward the lowest recessed portion is generated, and the rear moving member Moves back and forth on the lower reciprocating guide.
In addition, since the rear moving member is fitted on the fixed shaft through the sliding member and the wheel is rolled to the lower guide portion, when the upper base moves back and forth, a frictional force is generated on the sliding member and acceleration due to an earthquake, etc. Is attenuated.

If the object support mechanism according to the first embodiment described above is used, the following effects are further obtained.
Since a lower restoration guide portion 51r is provided in the lower guide portion, and the lower restoration guide portion 53r is located on the lower reciprocating guide portion 51r and has a concave contact surface, the rear moving member is lifted when the upper frame is lifted and lowered. Is guided to the lower restoration guide unit and restored to the lower round trip guide unit.

If the object support mechanism according to the second embodiment described above is used, the following effects are further obtained.
Since the lower upper guide portion 54r is further connected to the end of the lower lower guide portion 52r and is inclined upward, when the horizontal acceleration acts on the object, the rear moving member is guided and the lower reciprocating guide is provided. Beyond the end of the part, it is guided by the lower lower guide part and moves downward, and is stabilized at a place where the lower lower guide part and the lower upper guide part are connected.

If the object support mechanism according to the third embodiment described above is used, the following effects are further obtained.
Since the lower drop guide portion 55r that is further connected to the end portion of the lower lower guide portion 52r and changes the direction in the front-rear direction and is inclined downward is provided with a horizontal acceleration on the object, the rear moving member is It is guided and passes the end of the lower reciprocating guide part, is guided by the lower lower guide part and moves downward, is guided by the lower drop guide part and moves downward, and is difficult to return.

If the object support mechanism according to the above-described fourth embodiment is used, the following effects are further obtained.
Since the rear upper frame and the rear lower frame are connected by the long hole and the shaft body, separation of the rear upper frame and the rear lower frame can be prevented.
Moreover, since the upper part of the rear lower mount is cut away, the height dimension of the object support mechanism can be reduced.
Also, the edge of the long hole with which the shaft body abuts when the upper base is lifted is recessed, and the rear moving member is moved back and forth when the upper body is lifted and the shaft comes into contact with the most recessed part of the edge. Since it is located above the guide, it is easy to restore after the earthquake has stopped.
