Abstract
An engine includes a cylinder pressure sensor inserted into a through-hole of a cylinder head. A sealing member that seals between a hole wall surface and a body-side wall surface. A dimension relationship of D1<D3×(D4/D2) is satisfied where: D1 is a distance in a direction of a central axis from a reference position of the sealing member to a first given position; D2 is a distance between the hole wall surface and the body-side wall surface at the first given position; D3 is a distance in the direction of the central axis from the reference position to a second given position; and D4 is a distance between the hole wall surface and the body-side wall surface at the second given position.
