1. A molding machine comprising: a first retention block; a second retention block disposed oppositely to the first retention block; a plurality of connecting bars whose opposite ends are fixed to the first retention block and the second retention block respectively; a movable block which can have linear motion between the first retention block and the second retention block; a linear motion driving source for the movable block, the driving source being mounted on one of the first and second retention blocks; a force transfer mechanism for transferring force from the linear motion driving source to the movable block so as to make the movable block have linear motion; and a load cell unit disposed to be loosely inserted into an end portion of a predetermined one of the plurality of connecting bars and placed between one of the first and second retention blocks and a locknut fastened to the end portion of the predetermined connecting bar; wherein at least partially any connecting bar where the load cell unit is not mounted, that is, any connecting bar other than the predetermined connecting bar includes a portion whose diameter is made smaller than a diameter of the predetermined connecting bar by a predetermined distance.
