Abstract: A sphygmomanometer according to the present disclosure includes a main body that is mounted with a pump and is to be disposed on a dorsal surface of a wrist and a cuff that is to be attached around the wrist. The cuff extends along a circumferential direction of the wrist from an ulnar side end portion of the main body to a palmar surface and is set to a length covering an ulnar artery or a length covering a radial artery beyond the ulnar artery of a wrist having a preset maximum wrist circumference. A fluid is supplied from the pump to the cuff to press the wrist. A blood pressure is calculated based on a pressure of the fluid contained in the cuff.

Abstract: An internal combustion engine includes: a cylinder block in which a cylinder is formed; a cylinder head including an intake port and an exhaust port, the cylinder head being integrally formed with the cylinder block; a water jacket covering circumferences of the cylinder, the intake port, and the exhaust port; a partition wall dividing the water jacket into a cylinder block side and a cylinder head side; and a knock sensor mounting boss provided on a side surface of the internal combustion engine, at a position on an extension line of the partition wall.
