PURPOSE:To increase reliability by a method wherein an output member is connected to a moving rack, engaged with a pinion rolling on a fixed rack, and the output member is moved linearly and reciprocally. CONSTITUTION:The fixed rack 2 and a guide rod 6 are secured to a case 1, the moving rack 10 is engaged with the guide rod 6 movably, the pinion 30 is engaged inbetween the fixed rack 2 and the moving rack 10, the rotating center shaft of the pinion 30 is connected to the eccentric shaft of a crank 28, rotating by the drive of a rotary motor, through a link 31 and the output member is connected to the moving rack 10. According to this method, engaging parts, whereat a high load is being applied, are reduced and, therefore, the maintenance and management of lubrication or the like may be facilitated and the reliability of the device may be increased. |
