PROBLEM TO BE SOLVED: To provide goggles which have excellent durability without reducing strength of a lens, have excellent visibility without obstructing a field of view, and can ensure sufficient antifogging properties without insufficient ventilation within a frame.SOLUTION: Upper/lower ends of link members 2 are pivotally supported on upper/lower walls near both side ends of a frame 1. The frame 1 includes an abutting groove 5 of a lens 3 on a front face periphery. A periphery of the lens 3 abuts the abutting groove 5. The link member 2 is formed in a general U-shape by an upper body 2a, a lower body 2b, and an intermediate body 2c. By rotation-operating the link members 2 by operation members 4 respectively, the lens 3 can be protruded from the frame 1.SELECTED DRAWING: Figure 6 |
