PURPOSE: To accurately perform positioning of a vibration isolating member by protruding an engaging protrusion in an internal surface of a shroud, pressing this engaging protrusion into a mounting hole, and mounting the vibration isolating member in the shroud. CONSTITUTION: The periphery of a cylinder 7 and a cylinder head 8 in a two-cycle engine is surrounded by a shroud 9. A vibration isolating member 10 is mounted in an internal surface of the shroud 9. Each mounting hole 20 is formed into a diameter smaller than an engaging protrusion 17, and by pressing in the engaging protrusion 17, the mounting hole 20 is diametrically spread by elastic deformation of the vibration isolating member 10. By restoring elasticity, force tends to contract the diameter, so as to prevent the engaging protrusion 17 from coming off, and the vibration isolating member 10 can be temporarily stopped to the internal surface of the shroud 9. Here is relatively provided rigidity in the engaging protrusion 17, on the other hand to form the vibration isolating member 10 of elastic material, consequently the engaging protrusion 17 can be easily pressed into the mounting hole 20. In addition, since the vibration isolating member can be temporarily stopped to the shroud, positioning the vibration isolating member can be accurately performed. |
