置。[Scope of Claim for Utility Model Registration] A decompression device for a vertical engine in which a decompression lever having a decompression cam and a decompression weight is rotatably mounted on the camshaft of the engine parallel to the axis of the camshaft, is formed to open in the opposite direction to the rotational direction of the camshaft, and an oil pressure receiving plate that receives the resistance force of the oil is firmly attached to the upper or lower surface of the decompression weight, and the oil pressure receiving plate is adjusted to the temperature of the engine oil. Therefore, the oil pressure receiving plate is made of a shape memory alloy in which the angle of inclination of the oil pressure receiving surface changes, and as the camshaft rotates, the angle of inclination of the pressure receiving surface of the oil pressure plate increases when the engine oil reaches room temperature or higher. A vertical engine decompression device that is characterized by:
