とする内燃機関の冷却水ドレンコック。A cylindrical drain cock body facing a water jacket of an internal combustion engine and screwed onto a cylinder block; a large diameter portion having an outer diameter approximately equal to the inner diameter of the drain cock body; and an outer diameter smaller than the inner diameter of the drain cock body. and a drain cock plug consisting of a small diameter part having a
The drain cock plug has the small diameter part inserted deep inside the drain cock plug, and the large diameter part is screwed into the drain cock body, and a valve port is formed inside the drain cock body, and the drain cock plug has a valve port formed inside the drain cock body. A valve portion for opening and closing the valve port is formed at the tip of the small diameter portion of the plug, and when the valve portion is in a position to close the valve port, there is a gap between the inner wall surface of the drain cock body and the inner wall surface of the drain cock body. A space is defined by the outer wall surface of the small diameter portion of the drain cock plug, and within the drain cock plug, a drainage passage is bored in the axial direction to communicate the space with an external space. A cooling water drain cock for an internal combustion engine, characterized in that a drain pipe extending in the axial direction is press-fitted into an opening facing a space.
