The intermediate portion of the strap 30 is along the surface of the seat bottom 1 and is guided by the seat bottom 1.
- the seat bottom 1 receives the pulling force, and the lock plate 21 can be operated smoothly and lightly with little resistance.
- FIG 32 and 33 show modified examples of the lock bracket 20 and the guide cylinder 24 of the lock mechanism R.
- the pair of guide cylinders 24 is prevented from being misassembled with respect to the lock bracket 20, and the rectangular insertion holes 20 a and 20 b opened at the front and rear walls of the left and right portions of the lock bracket 20 are provided.
- a concave portion d for preventing misassembly is formed on one side, while the portions corresponding to the insertion holes 20a and 20b at both ends in the longitudinal direction of the guide cylinder 24 are the same as the insertion holes 20a and 20b. It is formed in a quadrangular shape, and a convex portion c that engages with the concave portion d for preventing misassembly is formed on one side thereof.
- the harness 41 inserted through the harness guide cylinder 42 is laid out at a position higher than the vehicle body mounting surface of the mount damper D, and the harness 41 does not interfere with the vehicle body BO.
- the degree of freedom of attachment is increased.
- An escape portion 75 is formed in 74, and it is possible to avoid the free ends of the pipe frames 12, 12 from interfering with the seat bottom 1 due to the back and forth movement of the backrest B.
- the seat device of the present invention is implemented in a scooter type motorcycle has been described, but it is needless to say that this can be implemented in other types of motorcycles.
- the backrest locking mechanism R a conventionally known one may be used instead of the one in the above embodiment.
