When the frames 3 and 4 are swung in the horizontal direction due to the earthquake and the joint portion 2 is widened, as shown in FIG. 9, the ride joint plate 9, the end joint plate 11, and the fixed joint plate 12 form the second joint plate support portion 8. It can slide to the left and right to absorb the shaking motion caused by the earthquake.

  At this time, a force is applied to the end joint plate 11 in the direction of the other casing 4 by the frictional force generated between the bottom surface of the end joint plate 11 and the second joint plate support 8. This force is also applied to the pivot pin 14 fixed to the support base 10, and a force in the same direction is also applied to the support base 10. As a result, a force is generated in the support base 10 so as to rotate in the left-right direction with the contact portion of the guide rail 16 and the sliding portion 22 as a fulcrum. Since the rotation prevention piece 21 is provided so as to contact, the support base 10 is prevented from rotating and falling off from the guide rail 16.

  When the casings 3 and 4 swing in different front and rear directions due to the earthquake, as shown in FIGS. 10 and 11, one end joint plate 11 is pressed against the wall surface 7 of the other casing 4 to push up the riding joint plate 9. While pushing up on the inclined surface 32, it sinks downward.

  When the shaking motion due to the earthquake ends, the one end joint plate 11 is urged toward the end side of the one housing 3 by the urging means 13 and returns to the normal state.
