A structure for installing a recording pen, in which a proximal end of the recording pen for recording a measured waveform on a sheet of recording paper is secured to a drive shaft of a driving source for oscillating the recording pen. The structure of the present invention comprises a cylindrical spacer, a pen-holder, packing, an installation screw, and an adjustment screw. The cylindrical spacer is fitted about and secured to the drive shaft and has a step portion formed at one end thereof, and also has an axial direction. The packing has an upper surface an outer side portion, and is formed from a resilient material. The packing is fitted about the outer peripheral portion of the cylindrical spacer and abuts against the step portion thereof. The pen-holder is fitted about an outer peripheral portion of the cylindrical spacer and abuts against an upper surface of the packing. The adjustment screw is screwed into the pen-holder to which the proximal end of the recording pen is secured, and penetrates into the pen-holder in a direction parallel to the axial direction of the cylindrical spacer. The distal end or tip of the adjustment screw is adapted to press against the outer side portion of the packing, thereby causing frictional interengagement therebetween. Installation screw is screwed in the pen-holder perpendicular to the axial direction of the cylindrical spacer and is adapted to secure the pen-holder thereto.
