Stringed instrument having height-adjustable bridge assembly

A stringed instrument comprising:

• a body;
• a plurality of strings being stretched along a neck;
• a hollow which is formed at a prescribed position and is elongated in a direction roughly perpendicular to the strings being stretched under tension;
• a bridge for supporting the plurality of strings under tension, a lower end portion of which is forked to form a pair of legs respectively having holes formed with internal threads;
• and
• a pair of height-adjustment members for respectively supporting the legs of the bridge, wherein each of the height-adjustment members is constructed by a screw rod and a foot which is partially held inside of the hollow in a free rotation manner and is manually rotatable by the hand of a human operator within the hollow,
• wherein an upper portion of the screw rod whose lower portion is buried in the foot is placed to engage with the internal thread of the hole of the leg being connected with the height-adjustment member.
