Kind Code:
A1
Abstract:
Provided is a damper device having good braking force responsiveness when the movement direction of a rack body is reversed. The damper device 100 comprises: a rack body 160 having a rack gear 170; a rotary damper 110 that has a pinion gear 120 engaging with the rack gear; and a case 130 that slidably holds the rack body and rotatably accommodates the rotary damper. The rotary damper has: a rotor 111 connected to the pinion gear; and a gear housing 115 that surrounds the rotor via a viscous fluid, is mounted to be rotatable relative to the rotor, and has a large-diameter gear 116 on the outer periphery thereof. The case has: an accommodation part 140 that accommodates a planetary gear 150 engaging with the large-diameter gear of the rotary damper such that the planetary gear 150 can move along a circumferential direction of the large-diameter gear by a predetermined distance; an engagement part 141 that is provided on one side of an inner wall of the accommodation part and restricts the rotation of the planetary gear when the planetary gear abuts the engagement part; and a rotation enabling part 142 that is provided on the other side, of the inner wall of the accommodation part, facing the one side, and enables the rotation of the planetary gear in a state in which the planetary gear abuts the rotation enabling part.
