Hinge structure

A hinge structure for mounting a swingable member which is swingable relative to a body member, comprising:

• a first knuckle formed on said swingable member;
• a second knuckle formed on said body member so as to be coaxial with said first knuckle;
• a pivot pin extending through said first knuckle and said second knuckle to join said first knuckle and said second knuckle to each other, said pivot pin being fixed to one of said first knuckle and said second knuckle so as to be prevented from rotating;
• and
• a frictional member fitted into the other of said first knuckle and said second knuckle, said frictional member including at least two contact wall portions which are in linear contact with a shaft portion of said pivot pin along an axial direction of said pivot pin.

A camera having a camera body and a swingable component hinged on said camera body, comprising:

• a hinge structure having a first knuckle fixed to said swingable component and a second knuckle fixed to said camera body coaxial with said first knuckle;
• and
• a pivot pin extending through said first knuckle and said second knuckle to join said first knuckle and said second knuckle to each other;
• wherein said pivot pin comprises at least one radial projection formed at one end of said pivot pin to extend radially outwards, a width of each said radial projection being smaller than a diameter of said pivot pin;
• and
• wherein one of said first knuckle and said second knuckle is provided with at least one groove which is formed at one end of said one of said first knuckle and said second knuckle, wherein said radial projection is fitted into said groove to prevent said pivot pin to rotate relative to said one of said first knuckle and said second knuckle.
