1. A seat support structure for a saddle-riding vehicle having a rider's seat and a pillion seat separate from and disposed
posterior to the rider's seat, the seat support structure comprising:
a bracket disposed on the rider's seat fixed to a vehicle body, the bracket providing a coupling between the rider's seat
and the pillion seat, wherein the bracket is detachably inserted in a front portion of the pillion seat when the pillion seat
is mounted to the vehicle body, and the pillion seat has a rear portion removably disposed on the vehicle body, the bracket
including a rearward extension extending rearwardly from the rider's seat when the bracket is connected to the rider's seat,
the rearward extension including an upwardly protruding engagement protuberance formed at a rear end of the rearward extension,

the pillion seat having a bottom plate formed of rigid material and a seat cushion section that covers the bottom plate from
above, the plate including a hook disposed on a lower surface at a lower front portion thereof, and the rearward extension
is insertable in the hook from a front of the hook,

the bottom plate including a lock protuberance disposed posterior to the hook, the lock protuberance being formed in a protruding
condition on the lower surface of the bottom plate such that the engagement protuberance protruding rearwardly from the hook
opposes a rear surface of the lock protuberance when the pillion seat is mounted to the vehicle body,

the hook having a hook bottom wall disposed below the bottom plate so as to form an opening between the hook bottom wall and
the lower surface of the bottom plate, the opening extending in the vehicle longitudinal direction so as to allow the rear
end of the rearward extension including the engagement protuberance to be inserted therethrough, and

wherein when the front portion of the pillion seat is raised out of engagement with the rider's seat while the rear portion
of the pillion seat is secured to the vehicle and the rearward extension is extended through the hook opening, the hook bottom
wall engages and bends the rear end of the rearward extension upwardly such that the engagement protuberance securely engages
with the lock protuberance.
