As a result, even if a seated person in the vehicle rear seat 70 wants to place drinks and accessories on the tray portion 31 of the table 30 of the vehicle front seat 20, the tray portion 31 is located close to the vehicle rear seat 70. It is possible to place drinks and small items on the tray portion 31 of the table 30 without taking an unreasonable posture in which the seated person in the rear seat 70 of the vehicle is greatly bent forward. Therefore, even for a seated person in the rear seat 70 of the vehicle provided on the rear side of the seat on which the table 30 is provided, the table 30 disposed on the side portion of the seat cushion 26 (seat component) can be easily used. Will be able to.
Furthermore, according to the vehicle seat 25 described above, the slide mechanism 50 is provided with the lock mechanism 60 that holds the tray portion 31 at any position within the range of movement of the tray portion 31 relative to the leg portion 41 (support base portion) including the lower rail 51. Therefore, the tray portion 31 can be held at an arbitrary position with respect to the leg portion 41 (support base portion). As a result, the position of the tray portion 31 can be maintained, so that drinks and small items can be stably placed. In addition, according to the vehicle seat 25 described above, the front lever operating portion 67 and the rear lever operating portion 68 are disposed at the front and rear portions of the tray portion 31, respectively. 67 and the release operation by the rear lever operation unit 68 are set along the direction in which the tray unit 31 is pulled. Therefore, the release operation of the front lever operation unit 67 and the rear lever operation unit 68 and the operation of pulling the tray are performed in series. Pulling operation. That is, when the seated person in the rear seat 70 pulls the tray 31 toward the rear seat 70 in order to place drinks and accessories on the tray 31, A pulling operation for bringing the tray unit 31 toward the rear seat 70 of the vehicle can be performed in conjunction with the release operation by the side lever operation unit 68. On the other hand, even if a seated person (for example, a driver) of the vehicle front seat 20 performs a pulling operation so that the tray unit 31 approaches the vehicle front seat 20, the front lever at the front of the tray unit 31 is used. A pulling operation for bringing the tray unit 31 toward the front seat 20 of the vehicle can be performed in conjunction with the release operation performed by the operation unit 67. Thereby, the operability in changing the relative position of the tray part 31 with respect to the leg part 41 (support base part) can be improved.
Further, according to the vehicle seat 25 described above, the slide mechanism 50 includes the lower rail 51 disposed on the seat cushion frame 27 via the leg portion 41 (support base portion) and the upper rail 55 disposed on the tray portion 31 side. The length of the lower rail 51 in the slide movement direction is set shorter than the length of the upper rail 55 in the slide movement direction. The formed rail structure can be blinded. Thereby, even when the tray part 31 is slid, the rail structure of the lower rail 51 is not shown, so that the appearance design can be improved as a clean appearance.

It should be noted that the vehicle seat according to the present invention is not limited to the above-described embodiment, and may be configured by appropriately changing the location as follows.
For example, the slide mechanism 50 and the lock mechanism 60 described above are only one embodiment according to the present invention. That is, in the slide mechanism according to the present invention, an appropriate configuration may be employed as long as the tray portion is slid relative to the support base portion. Further, in the lock mechanism according to the present invention, as long as it has a function of holding the relative position of the tray portion at any position in the range of movement of the tray portion with respect to the support base portion, it is appropriately The configuration may be adopted. That is, in the lock mechanism 60 of the above-described embodiment, the outer peripheral surface 621 of the fastening cam 62 abuts against the inner peripheral surface 521 of the housing bottom 52, so that there is a gap between the outer peripheral surface 621 and the inner peripheral surface 521. The relative position holding state in which the relative position of the upper rail 55 with respect to the lower rail 51 is held by the generated frictional force. For this reason, the relative position of the upper rail 55 with respect to the lower rail 51 can be held at any position that becomes an unrestricted floor. However, the locking mechanism according to the present invention is configured to lock the relative position of the upper rail 55 with respect to the lower rail 51 in a stepwise manner, such as a slide mechanism that slides the vehicle seat itself with respect to the vehicle floor. There may be.
Moreover, the support base part which concerns on this invention should just be fixedly installed so that it cannot move relatively with respect to seat structure parts, such as a seat cushion, and is limited to the leg part 41 in above-described embodiment. Instead, an appropriate mounting component such as a bracket may be used.
