Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the abrasion quantity of the toggle bush and link pin toggle bearing of a toggle type injection molding machine and to enhance the durability thereof. SOLUTION: Bearing steel is used in the toggle bushes 13, 14, 15, 16, 17 of a toggle bearing and nitride steel, chromium/molybdenum steel or martensite stainless steel is used in link pins 4, 6, 7, 9, 10 being partner materials and the surface hardness thereof is made higher than the hardness of a bush material by 5-15 as Shore hardness. The Shore hardness of bearing steel is pref. 80±5.
