Title:
LINEAR ACTUATOR
Document Type and Number:
Japanese Patent JP2017015144
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear actuator capable of reducing the rattling of an advancing and retreating shaft part.SOLUTION: A linear actuator 100 advancing and retreating a shaft 2 to the axial direction includes: a first tapered bush 14 having a first through hole 14a through which the shaft 2 goes and a tapered surface 14c, and supporting the shaft 2; a second tapered bush 15 having a tapered receiving surface 15b tilted so as to receive the tapered surface 14c and supporting the tapered surface 14c, and provided adjacently to the first tapered bush 14 around the shaft 2; and a wave washer 12 pressing the first tapered bush 14 and the second tapered bush 15 with each other. The first tapered bush 14 is flexible in the radial direction of the first through hole 14a, the tapered surface 14c is tilted to the radial inner side of the shaft 2 toward the second tapered bush 15, and the second tapered bush 15 is fixed in the radial direction of the shaft 2.SELECTED DRAWING: Figure 2
