- the lower link arm 104b is rotated upward while sliding on the elevating guide pin 106, and the seat body 101 is moved from the lowered position to the raised position.
- the lower link arm 104b is formed in a curved shape so as to move the seat body 101 up and down along a predetermined locus.
- the above-described conventional vehicle seat moving device is configured such that the lower link arm 104 b formed in a curved shape with the movement of the slide base 103 is supported from below by an elevating guide pin 106. It is configured to rotate up and down while sliding on the lifting guide bin 106. Therefore, the distance L from the fulcrum P of the lower link arm 104 b supported by the elevating guide pin 106 to the center of rotation Q of the lower link arm 104 b corresponds to the movement of the slide base 103. Therefore, when the slide base 103 is moved by a driving device using an electric motor as a drive source, the load applied to the electric motor greatly changes. Such a large fluctuation range of the load acting on the electric motor has a problem that the deterioration of the electric motor is accelerated.

Further, the stopper can be simply configured when forming the elevating guide member, and the number of parts can be reduced.
- the elevating guide member is constituted by a cam plate, and the supported portion of the seat elevating arm is constituted by a roller rolling on the cam plate. Therefore, according to the present invention, the seat body can be smoothly lowered and raised along the predetermined trajectory.
- the sheet elevating arm is composed of two plates arranged at a predetermined interval and a coupling member for coupling the opposite ends of the two plates to each other, and a roller is disposed between the two plates. It is characterized by having. Therefore, according to this invention, the sheet elevating arm is constituted by two plates opposing each other at a predetermined interval, so that the sheet elevating arm has a thickness direction (compared to, for example, a single plate). The rigidity with respect to the plate disposition direction can be increased, and the roller can be a stable support form having both ends. As a result, it is possible to prevent or reduce the roll of the seat body when moving up and down or moving horizontally.
