To provide an injection molding machine improved in maintenance properties.

In the injection molding machine 1 equipped with a toggle link mechanism 15 for performing mold clamping by a mold clamping drive means 8 for opening and closing a mold, roll bearings 30 equipped with a solid lubricating members 33 impregnated with a lubricant are interposed between the connection parts of a plurality of the link arms 21, 22, 23 and 24 connected to the toggle link mechanism 15 in a freely revolvable manner. Accordingly, the lubricant is leached from the solid lubricating members 33 accompanied by the extending and bending operation of a plurality of the link arms 21, 22, 23 and 24 connected in the freely revolvable manner to smoothly operate the link arms 21, 22, 23 and 24.
