PROBLEM TO BE SOLVED: To enable the connection of a crank rod to a junction rod at a lower position than the seat surface of a front passenger seat by converting the rotation of the crank rod into frontward and rearward rocking motion in the horizontal direction at the lower part of the front passenger seat.SOLUTION: A crank rod 1 is rotatably laid and arranged in a space between the bottom parts of a driver seat DS and a front passenger seat SS of an automobile and an in-vehicle floor surface CF in a range from the lower part on one side of the driver seat DS to the lower part of the front passenger seat SS, an operation lever 2 is protruded upward from the base end of the crank rod 1 existing at the lower part on one side of the driver seat DS, a crank 1a is protruded downward from the front end of the crank rod 1 existing at the lower part of the front passenger seat SS, a downward front end 1b of the crank 1a is linked to one end of a lever rod 5 which is provided at the lower part of the front passenger seat SS so that both ends alternately rock frontward and rearward in the horizontal direction, and the other end of the lever rod 5 is linked to the front end of an arm rod 9 which is curved and protruded to the lower part on one side of the front passenger seat SS in front of the inside of a rear door BD provided via a junction rod 10 in the diagonal direction of the driver seat DS. |
