The upper shaft member 45 is provided outside the lower shaft member 44 in the vehicle width direction. The upper shaft member 45 is inserted into the hole provided at the other end of the support member 43 and the hole of the bearing portion 18 provided in the intermediate plate 20 and the other end of the support member 43 and the intermediate plate 20, As shown in Fig.

As a result, when the intermediate plate 20 is moved away from the lower plate 10, the support member 43 has the lower shaft member 44 as its rotation axis and the end on the intermediate plate 20 side As shown in Fig. Therefore, the movable unit 40 can move the intermediate plate 20 upwardly and inwardly in the vehicle width direction with respect to the lower plate 10.

On the other hand, when approaching the intermediate plate 20 with respect to the lower plate 10, the support member 43 has the lower shaft member 44 as the rotation axis, and the end on the side of the intermediate plate 20, . Therefore, the movable unit 40 can move the intermediate plate 20 downward and outward in the vehicle width direction with respect to the lower plate 10.

The first movable unit 41 and the second movable unit 42 constituting the movable unit 40 are arranged shifted in the vehicle width direction. In the present embodiment, the first movable unit 41 is provided outside the second movable unit 42 in the vehicle width direction. The length of the first movable unit 41 in the vehicle width direction is the same as the length of the second movable unit 42 in the vehicle width direction. This length is adjusted in accordance with the height of the protruding portion 6 of the vehicle 2.

8, when the upper plate 30 and the lower plate 10 are apart from each other, the first movable unit 41 and the second movable unit 42 move the intermediate plate 20 in the vehicle width direction As shown in FIG. Therefore, it is possible to prevent the upper plate 30 from shaking in the vehicle width direction.

The length of the first movable unit 41 in the vehicle longitudinal direction is longer than the length of the second movable unit 42 in the vehicle longitudinal direction. 7, when the upper plate 30 and the lower plate 10 are in an approaching state, the second movable unit 42 is arranged so as to overlap the inner side of the first movable unit 41 do. Therefore, the reinforcing portion 432 of the second moving means 42 and the reinforcing portion 432 of the first moving means 41 can be prevented from coming into contact with each other.

As shown in Figs. 3 and 8, a tensile spring 50 is provided as a biasing means for biasing between the lower plate 10 and the intermediate plate 20. One end of the tension spring 50 is connected to the lower stopper 51 provided on the lower plate 10 by bolts 52 and the other end is connected to the upper stopper 53 (Not shown).

The upper engaging portion 53 connecting the tension spring 50 to the intermediate plate 20 is provided at the same position as the upper shaft member 45 of the first moving means 41 or at the outer side thereof have. The lower engaging portion 51 connecting the tension spring 50 to the lower plate 10 is provided on the inner side of the lower shaft member 44 of the first movable means 41 in the vehicle width direction. Thus, when the lower plate 10 and the intermediate plate 20 are in the approaching state, the tension spring 50 is extended longer than the support member 43 of the first movable unit 41, The intermediate plate 20 is biased in the pulling direction toward the inside of the vehicle width direction. Therefore, when the lower plate 10 and the intermediate plate 20 move away from each other, the tensile spring 50 is reduced in overall length, thereby assisting the upward movement of the upper plate 30. Further, when the lower plate 10 and the upper plate 30 are apart from each other, the tension spring 50 prevents the upper plate 30 from descending and maintains the position of the upper plate 30.

3 and 8, the stopper belt 55 has one end fixed to the end of the first movable unit 41 on the side of the intermediate plate 20, and the other end fixed to the lower plate 10 have. The stopper belt 55 regulates the moving range of the intermediate plate 20 to the inside in the vehicle width direction. The length of the stopper belt 55 is set so that the protrusion 6 of the vehicle 2 and the upper plate 30 are not in contact with each other when the lower plate 10 and the upper plate 30 are apart from each other. This can prevent the protrusion 6 of the vehicle 2 from contacting the top plate 30 when the seat 3 is moved upward and further inward in the vehicle width direction.

10, the first fixing means 60 includes a guide member 61 fixed to the lower plate 10, a lock lever 62 mounted on the guide member 61, The first engaging member 63 and the second engaging member 64 provided in the first and second engaging members 30 and 30, respectively.

The compression spring 15 may be fixed to the upper plate 30.

The compression spring 15 is a support for separating the upper plate 30 and the lower plate 10 from each other.

(6) In the present embodiment, one end of the tension spring 50 is connected to the lower plate 10, and the other end is connected to the intermediate plate 20. The tension spring 50 is extended longer than the support member 43 when the lower plate 10 and the intermediate plate 20 approach each other and the intermediate plate 20 is extended with respect to the lower plate 10 And biased in a direction pulling inward.

Thereby, the user can move the seat 3 upwardly and further inward in the vehicle width direction by a light force. The tension spring 50 can prevent the upper plate 30 from falling even when the lower plate 10 and the upper plate 30 are separated from each other and the movable means 40 is inclined.

(7) In the present embodiment, the convex-shaped rotation stopper 39 protruding downward from the upper plate 30 comes into contact with the contact portions 23 and 24 provided on the intermediate plate 20, The angle range is regulated.

Thereby, it becomes possible to stop the rotation of the seat 3 at a predetermined position. Therefore, it is possible to easily fix the upper plate 30 whose rotation is restricted by using the first fixing means 60 or the second fixing means 66.

(8) In the present embodiment, the stopper belt 55 regulates the moving range of the intermediate plate 20 to the inside in the vehicle width direction.

This prevents the upper plate 30 from contacting the projections 6 and the like of the vehicle 2 when the seat 3 is moved upward and further inward in the vehicle width direction. Further, the seat 3 is held at a predetermined position by the interaction of the stopper belt 55 and the tension spring 50.

(9) In the present embodiment, the lower plate 10 has a hole 16 at a position corresponding to the support member 43.

Thereby, it is possible to reduce the weight of the seat rotating apparatus 1. Further, even when the seat 3 is vibrated, the support member 43 and the lower plate 10 can interfere with each other to prevent sound from being generated. Furthermore, by storing the support member 43 inside the hole 16 of the lower plate 10, it is possible to lower the height of the seat rotating apparatus 1. [
