Here, the pressing member 504 is provided with a through hole 5041 so that a part of the top surface of the male screw 507 is exposed. The inner diameter of the through hole 5041 is formed to be smaller than the outer diameter of the head of the male screw 507. However, the inner diameter of the through hole 5041 is formed to be larger than the outer diameter of the tip of a tool such as a screwdriver for turning the male screw 507. As a result, the position of the saddle 505 in the chord direction can be easily adjusted even while the pressing member 504 is fixed to the neck side wall member 503.

The position of the bridge portion 50 shown in FIGS. 10 and 11 in the chord direction of the saddle 505 can be adjusted by inserting a tool such as a screwdriver into the through hole 5041 from the neck side. Therefore, there is no problem with the guitar 1 (FIG. 1, a type such as a so-called precision bass) in which the pickup 11 is installed sufficiently away from the bridge portion 50. However, problems arise with guitars where the pickup 11 is installed near the bridge 50 (eg, a type such as a so-called jazz bass). For example, the handle of a tool such as a screwdriver or the hand of an operator is obstructed by the pickup 11, and the tool such as a screwdriver cannot be successfully inserted into the through hole 5041 from the neck side. Therefore, the bridge portion 50 may be configured as the bridge portion 50A described below.

FIG. 12 is an exploded view showing another example of the bridge portion. FIG. 13 is a plan view of the bridge portion. In FIGS. 12 and 13, the base portion 41 is shown by a broken line. The bridge portion 50A will be described focusing on the points different from the bridge portion 50.

The head of the male screw 507A is formed in a columnar shape, and one or more through holes 5071A are formed in the diameter direction thereof. Instead of the through hole 5071A, a bottomed hole may be formed. The saddle 505 can be moved in the chord direction by inserting a tool such as a wrench into any of the through holes 5071A and rotating the male screw 507A to the left or right. The pressing member 504 is provided to press the head of the male screw 507A and limit the movement of the saddle 505 in the neck direction. The presser member 504 does not have to be provided with a through hole 5041 (FIG. 10). Further, a shaft portion of each male screw 509 is provided between the pressing member 504 and the neck side wall member 503 so that the head of the male screw 507A is not difficult to rotate between the pressing member 504 and the neck side wall member 503. A spacer (for example, a cylindrical spacer) to be penetrated may be sandwiched. The chordal dimension of each spacer is formed longer than the chordal dimension of the head of the male screw 507A.

By using the bridge portion 50A, a rod-shaped tool such as a wrench can be inserted into the through hole 5071A from above or in the left-right direction of the main body portion 10. As a result, the position of the saddle 505 in the string direction can be adjusted without being disturbed by the pickup 11 or the like installed near the neck side of the bridge portion 50A.

Finally, an example of the disassembly procedure when carrying the guitar 1 will be described. (1) For each string S, the male screw 408 is turned in a predetermined rotation direction to move the locking member 405 in the neck direction to loosen the tension of the string S. (2) The male screw 315 is turned in a predetermined rotation direction to remove it, and the neck side string locking portion 30 is removed from the base portion 31.
