Abstract: A thermoelectric power generator has: a pair of thin film sheets that respectively cover a heat receiving side and a cooling side of a thermoelectric element; a resin sealing portion that is superposed with the pair of thin film sheets, in a state of being nipped between the pair of thin film sheets, at a periphery of the thermoelectric element; a heat insulating layer that is disposed at a heat receiving side of the resin sealing portion and that is superposed on one of the pair of thin film sheets; and a presser plate that presses the heat insulating layer toward the resin sealing portion, and that is formed in a stepped shape at which a plate thickness of a region at a side contacting the heat insulating layer is thicker than a plate thickness of a fixed region that is fixed by a fixing portion.

Abstract: A gas spring is intended to permanently maintain the sealing performance of a lip in a dust seal without being affected by pressure from a gas sealed inside the spring. A rod body is operates in conjunction with a cylinder body with a gas of a predetermined pressure sealed inside the cylinder body. The rod body is movable into and out of the cylinder body. A rod guide is penetrated by the rod body at a shaft core portion inside a head end portion of the cylinder body. A dust seal has with a lip in sliding contact with an outer circumference of the rod body. A sealed end portion of the cylinder body is in contact with an outer end of the rod guide inside the cylinder body. The dust seal is integrally incorporated at the outer end portion of the rod guide.
