Conventionally, this type of seat elevating device connects the seat frame to the lower frame so that it can rise and fall using a rotation support member, and a fan-shaped gear that interlocks with the rotation support member engages a gear that interlocks with an operating lever. However, a configuration has been proposed in which the seat frame is raised and lowered by rotating the operating lever by an appropriate amount, and then locked by a brake mechanism using a spring body. Although it has the advantage of being able to be operated with a single button, it has the disadvantage of requiring a large number of operations and is complicated to operate, and the structure is complex, heavy, and expensive, especially for small cars. It is difficult to apply this method, and it also has the disadvantage that it tends to interfere with the seat cushion, making it impossible to obtain a comfortable sitting feeling.

First, in a state where the seat frame (1) is located at the lowest level and the stop arm pin (131) is engaged and locked in the retention hole (111) provided in the connecting link (9b), the seat frame (1) is locked. (When you pull 131 toward you, the tip (13a) of the stopper or bottle a3 comes out of the through hole (16a) drilled in the bracket αe, and then the retaining hole (13a) drilled in the connecting link (9b) ( 111 and the locked state is released.Then, the front bell crank (which had been biased in the direction of rotation by the biasing force of the spring (II)
3a) (3b) and rear bell crank (4a) (4b)
) rotates, and the seat frame (1) rises with respect to the slide rails (2) (2') and is positioned at the top level.
