Claims

[Scope of utility model registration request]

It has a cylindrical shape with a narrow inner and outer diameter at the distal end and a thicker inner and outer diameter at the proximal end, and the distal end has a plurality of grooves in the axial direction of the tube. A circuit board having a hole drilled at a position corresponding to the fixing part is attached to the base by inserting the fixing part into the hole, and the base end of the press-fit part is connected to the tip of the fixing part. The press-fitting part is thicker than the inner diameter and becomes thinner toward the distal end, and the distal end is provided with an engaging part that engages with an internal stepped part between the proximal end and the distal end of the fixing part. A fixing structure that is press-fitted into the fixing part from the circuit board side and fixed.
