The insertion amount of 0 is defined, and the protrusion 321 is prevented from falling out of the groove by the locking portion 252 of the positioning groove 251 and the protruding portion 322 of the protrusion 321. Therefore, the body 20 and the neck 30 are fixed not only by the neck connecting screws 121 and 122 in the longitudinal direction of the neck insertion groove 23 but also by the protrusion 321 at a position apart from them. Therefore, the neck connecting screw 12
Since the fixing by means of No. 1 and 122 is only required at one place in the longitudinal direction of the neck insertion groove 23, the small pickup 21
The neck connecting screws 121 and 122 can be hidden by one piece. Therefore, not only does the electric guitar 10 of this example look good, but the connecting work is simple.

The connection structure of this example is the Echire guitar 1
Although 0 has been described as an example, it may be applied to a banjo and other stringed instruments if it is necessary to connect the body and the neck. Even in the case of a stringed instrument having a structure in which a pickup is not provided, such as an acoustic guitar instead of an electric guitar, a blind member having a fingerboard or the like may be mounted in the recess to hide the neck connecting screw.

Further, as the blindfold member, instead of the pickup 211, a resin panel such as a pickguard covering the recess 31 or a decorative cover may be used.

Further, the protrusion 321 is provided on the back surface 3 of the neck 30.
03, the positioning groove 251 is formed in the neck insertion groove 23.
Formed on the bottom surface 231 of the

Further, the recess 31 is formed as a step on the base end edge of the neck 30.
If the base end portion 301 is 0, it may be an intermediate position in the length direction.

Further, in this example, the neck connecting screws 121, 122 are provided at one position in the longitudinal direction of the neck insertion groove 23.
The structure is such that the neck 30 is screwed in and the neck 30 is fixed via the protrusions 321 at positions apart from each other in the longitudinal direction of the neck insertion groove 23. However, instead of this structure, two positions in the longitudinal direction of the neck insertion groove 23 are provided. Even if screwed, the appearance and the efficiency of the connecting work can be improved as compared with the conventional connecting structure.
