1. A gas generator for a restraining device of a vehicle, comprising: a housing being made of a resin, forming an outer shell container, and having a plurality of gas discharge ports that extend through the outer shell container,an ignition device disposed inside the housing,a gas generating agent that is ignited and burned by activation of the ignition device,each of the plurality of gas discharge ports being formed by each of a plurality of ring members that are embedded in a circumferential wall of the housing and which are formed of a material selected from the group consisting of metals, ceramics, and carbon fiber, andthe each of the ring members being embedded such that an annular surface at one end thereof is exposed from an inner wall surface of the housing and an annular surface at the other end thereof is directed to an outer side of the housing. 2. The gas generator for a restraining device of a vehicle according to claim 1, wherein the ring member comprises a larger-diameter portion and a smaller-diameter portion that are concentrically arranged and also comprises a central hole that passes through central portions of the larger-diameter portion and the smaller-diameter portion, andthe larger-diameter portion and the smaller-diameter portion are embedded partially, an annular end surface of the larger-diameter portion is exposed from the inner wall surface side of the housing, a distal end surface of the smaller-diameter portion recedes from the outer wall surface of the housing, and the central hole of the ring member forms a gas discharge port. 3. The gas generator for a restraining device of a vehicle according to claim 1, wherein the ring member comprises a larger-diameter portion and a smaller-diameter portion that are concentrically arranged and also comprises a through hole that passes through central portions of the larger-diameter portion and the smaller-diameter portion,the larger-diameter portion and the smaller-diameter portion are embedded partially, and a sloping hole portion is formed at a tip of a distal end surface of the smaller-diameter portion, andthe sloping hole portion includes an inner diameter that increases toward an outer wall surface of the housing.
