Abstract
A clamping device includes: a stationary platen; a rear platen; a tie bar; a moving platen; a toggle mechanism connected to both the rear platen and the moving platen and used for making the moving platen advance and retreat; a guide rod having one end fixed to the rear platen and the other end extending toward the moving platen; a guide rod support supported by the tie bar at a supported part and supporting the guide rod at a supporting part; and a crosshead configured to advance and retreat under guidance by the guide rod. The advance and retreat of the crosshead expands and contracts the toggle mechanism to make the moving platen advance and retreat. The guide rod support is provided in such a manner that the supported part is arranged rearward of the supporting part and closer to the rear platen than the supporting part along a center axis.
