A slide locking apparatus (10) for a seat, including: a first locking section provided on an upper rail (2) and a plurality of second locking sections (14 to 15b) provided on a lower rail (1) so as to be able to lock with and unlock from the first locking section. The first locking section has a plurality of locking pieces (3a to 3e) aligned in the lengthwise direction on the upper rail. The plurality of second locking sections are aligned in the lengthwise direction on the lower rail and constitute at least one second locking section group. The second locking section group is configured such that, when at least one of the plurality of locking pieces locks with one of a forwardmost second locking section disposed in a forwardmost position, a rearwardmost second locking section disposed in a rearwardmost position, and an intermediate second locking section disposed between the forwardmost and rearwardmost second locking sections, in a substantially simultaneous fashion therewith, another locking piece of the plurality of locking pieces can lock with another second locking section of the second locking section group. The slide locking apparatus for a seat further includes at least one of a first lock inhibiting means (5a) which inhibits the forwardmost second locking section from locking with any of the locking pieces when the rearwardmost locking piece of the plurality of locking pieces has entered into a region at a forward position of a lockable position where the rearwardmost locking piece coincides with an intermediate second locking section that is adjacent to the forwardmost second locking section of the second locking section group, and a second lock inhibiting means (5b) which inhibits the rearwardmost second locking section from locking with any of the locking pieces when the forwardmost locking piece of the locking pieces has entered into a region at a rearward position of a lockable position where the forwardmost locking piece coincides with the intermediate second locking section that is adjacent to the rearwardmost second locking section of the second locking section group.
