Claims

[Scope of utility model registration request]

A support piece for adjusting, mounting and supporting a shaft bearing body is provided at one end of the vehicle chassis running on the rail, and the shaft bearing body has a pulley driven by a drive source at one end and a pulley connected to the pulley at the other end. A swinging arm is provided with a rotating shaft that rotates by rotating, and a removable cutter is provided on the rotating shaft, and a groove is bored in the head of the rail by the cutter by the movement of the swinging arm. The groove boring device is characterized in that the support piece is provided with a pair of trochanters that sandwich the rail, and the movement of the trochanter causes the support piece to slide along the chassis following the rail. Groove drilling device for rails.
