Abstract: A vacuum-sealing device includes: a first roll; a second roll that contacts the first roll; a first holding member having a first space in which the first roll is held and which has an axis coincident with an axis of the first roll; and a second holding member having a second space in which the second roll is held and which has an axis coincident with an axis of the second roll. The first holding member has an inner circumferential surface that faces the outer circumferential surface of the first roll, and rotation of the first roll and the second roll in correspondence with each other causes a sheet material to pass.

Abstract: An electrically driven cylinder in which the supply of a lubricant is not needed for a long period of time. The electrically driven cylinder, comprising: a screw mechanism portion that converts rotational motion of an electric motor into linear motion; a rod that reciprocates by linear motion of the screw mechanism portion; a bushing member that regulates swinging of the rod; and a key member which is inserted into a rod groove portion provided along an axial direction of the rod and which regulates rotation of the rod; a lubricant being sealed in the screw mechanism portion, the bushing members having a plurality of holes in which a lubricant is embedded, and the key member having a plurality of holes in which a lubricant is embedded.
