PURPOSE:To form a seat track directly on a seat rotary device by forming a lower bracket and an upper rail integrally. CONSTITUTION:Lower rails 1, 2 are fixed on the car floor and a lock plate is provided on one of them. An upper rail section 11 is provided integrally on both sides of a lower bracket 10. The upper rail section 11 is made of an inside rail member 13 different from the outside rail section 12 which is formed by bending both sides of the lower bracket 10 or the lower bracket 10 to be fixed at the inside, and a lock mechanism 15 to be engaged with the lock plate 8 is provided on one inside rail member 13. With such structure a seat track can be formed directly on a seat rotary device to simplify the structure, to reduce the weight and the assembling manpower, resulting in the improvement of workability and the cost reduction. |
