PROBLEM TO BE SOLVED: To achieve the reduction of the number of work processes and the enhancement of production efficiency by shortening the time required in the adjustment of mold thickness and to exclude room letting an error enter to ensure sufficient accuracy and stability. SOLUTION: This mold thickness adjusting method of a toggle type mold clamping device has a first process T1 for allowing a pressure receiving plate 2 to advance at a first speed Vh becoming a high speed from a retreat position Xr in a state that a toggle link mechanism 3 is stretched and allowing the pressure receiving plate 2 to retreat by a predetermined distance Ls when the pressure receiving plate 2 reaches a mold closing position Xc and a second process T2 for allowing the pressure receiving plate 2 to advance at a second speed Vs becoming a low speed after the first process to bend the toggle link mechanism 3 after the pressure receiving plate 2 reaches the mold closing position Xc to perform mold opening by a predetermined distance Lr and subsequently advancing the pressure receiving plate 2 by the distance Lc corresponding to clamping quantity obtaining target clamping force.
