The flexible arm 8 is constituted with a coil 80 and a tube 90 provided on an outer periphery thereof. The coil 80 is formed as a double-strand coil containing a wire rod, stainless used steel for coil springs with high tensile strength, (SUS304WPB) 82 having a round cross-section and a Stainless Used Steel wire rod (SUS) (SUS304) 84 having a triangular cross-section. On the outer periphery of the coil 80, the tube 90 made of silicone is provided so as to be in close contact therewith. By making an outside diameter of the coil 80 slightly larger than the inside diameter of the tube 90 (approximately 10% of the tube diameter), the tube 90 fits tightly to the outer periphery of the coil 80. The tube 90 is fitted over the coil 80 in a state stretched from a natural state thereof in a direction A in the figure. Accordingly, the flexible tube 90 attempts to move in the contraction direction, and therefore force in a direction compressing the coil 80 can be applied. Thus, the bent state of the flexible arm 8 can be maintained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flexible arm and head-mounted display","description":"The present invention provides a head mounted display and flexible arm that is easily bendable yet capable of maintaining a bent state thereof.
