A joint cover device includes a joint cover which covers a joint part of right and left building members. The joint cover has ends supported on surfaces adjacent the joint part. A retaining device is provided for retaining the joint cover in a central position. The retaining device has ends attached to the right and left building members. The retaining devices further include a first bar member that engages a gear and has one end rotatably a side portion of one of the building members in a horizontal direction. A second bar member engages the gear and has one end rotatably attached to a side portion of the other building member in a horizontal direction. The first bar member faces the second bar member in an inclined orientation relative to the building members. The gear engages the first bar member and the second bar member. A support member is pivotably attached to a pivot pin at a central portion of the joint cover and supports rotatably the gear and slidably supports the first and second bar members so that the joint cover device can absorb vibration and swing movement because of rotation of the bar member in a horizontal direction and geared engagement of the bar members when the right and left buildings are oscillated relative one another.
