PURPOSE:To perform assembling work quickly and reliably in a work table assembly where the assembling work of a car seat is held in the same condition as in the usage to perform the assembling work quickly and reliably by providing a projection to be engaged in a fixed hole of the seat table and an engaging rod retreatable by means of a solenoid. CONSTITUTION:A metal frame 6 for a car seat is lifted by hand then the hole 11 in a bent section 9 at the front edge is engaged with a projection 26 then the rear end is lowered onto the rear mounting table 29, and the bent section 10 of the metal frame 6 will contact tightly against the rear face 31 of said table 29 to match said hole 12 with the engaging holes 33, 34. Upon turning on the solenoid switch, the engaging rod formed at the leading edge of the rods 37, 38 will advance to be pierced into the engaging hole 33 through a hole 12 at the bent section 10 of the metal frame 6 to fix the metal frame 6. |
