  • the lock lever 20a 'of the interlock mechanism 20' includes an engagement lever 250 that engages with the cam jaw 120 shown in FIGS. 14 and 15 and a push-up lever 25 1 that pushes up and supports the engagement lever 250.
  • the engagement lever 250 is attached to the side surface of the upper rail 2a because the base side is pivotally connected to the support shaft 250a.
  • the push-up lever 251 is attached to the side surface of the upper rail 2a because its upper side is pivotally connected to a shaft 251a.
  • the engagement lever 250 has a guide pin 252 which is inserted into a guide hole 250b provided in a substantially middle abdominal side and protrudes laterally from the pin holder 253, and the push-up lever 25 1 is provided with the guide plate 20b. Is provided so as to be pushed up so as to engage with the receiving jaw 120 of the stopper mechanism 10 ′ when it comes into contact with the stopper mechanism 10 ′. Also, it is attached so that the posture is held by a spring 254 that is bridged between the substantially middle abdomen of the engagement lever 250 and the side surface of the pin holder 253.
  • the entire seat is in the normal sitting position, and the restriction pin 11 on the upper table side has the notch 1 of the rotating cam 1 O b 'provided on the lower table side. 0 4 ′, so that the upper tape side of the turn tape J 1 also keeps the turn tape from rotating. This keeps the entire seat unturnable by the turntable 1 at the slide stop position.
