Abstract
A gas engine includes a cylinder head, a prechamber cap that projects into a main combustion chamber by being inserted into an insertion hole formed in the cylinder head, that internally has a prechamber, and that supplies a flame generated in the prechamber to the main combustion chamber, and a prechamber holder that is disposed inside the cylinder head so as to hold the prechamber cap. One of the prechamber cap and the prechamber holder has a concave portion which accommodates an end portion of the other of the prechamber cap and the prechamber holder. An outer diameter of the end portion is set to be smaller than an inner diameter of the concave portion, thereby forming a space between the concave portion and the end portion at least in a radial direction orthogonal to a central axis.
