の肘掛け上下位置調節装置を提供した。Accordingly, the applicant of the present application has previously filed Japanese Patent Application No. 6-1.
No. 85724 (Japanese Patent Application Laid-Open No. 7-108015) provides an armrest vertical position adjusting device.

ラックに係合するようになされている。In this apparatus, a column support for holding a pin engaging with teeth of the rack is externally fitted to a column in which a rack is installed in the vertical direction, and an armrest body is covered with the column support to vertically support the column. It is movable in the direction, and a ring-shaped support is interposed between the armrest main body and the support. The pin is removed from the rack by pressing a switch of the support, and the rack is engaged when released. .

いものとなり、これが椅子のデザインに制約を与え、す
っきりした形態の椅子とすることが難かしいという問題
点があった。However, according to the above arrangement, the armrest can be adjusted freely to set the height at an optimum height for the occupant. Due to the structure, the circumference of the support of the armrest is inevitably thick, which restricts the design of the chair, and there is a problem that it is difficult to make the chair in a neat form.

ックのピッチの設定にも限界があることから微小な高さ
調節ができないという問題点があった。Further, in adjusting the height of the armrest, since the two pins have the same pitch as the pitch of the teeth of the rack, the pitch of the rack is adjusted one pitch at a time, and thus the setting of the pitch of the rack is limited. For this reason, there has been a problem that the height cannot be finely adjusted.
【０００８】本発明はこれに鑑み、肘掛けの支柱部分を

のである。As a means for solving the above-mentioned problems, the present invention provides a chair provided with an armrest, in which a guide tube provided upright on a side of a seat and a valley provided in the guide tube are provided. A rack member having racks vertically arranged at regular intervals; a sliding member which is vertically installed below the elbow pad and which can be inserted into the rack member and slidable in the vertical direction; An operating member whose upper end is pivotally supported and is capable of being pressed from the outside from the outside against a spring bias, and an upper and lower pair which is slidably held by the sliding member in a lateral direction and can be engaged with the rack. An engaging pin, and a pin guide having a central portion pivotally supported at the lower end of the sliding member so as to be swingable and holding the upper and lower engaging pins. When the pin fits into the valley of the rack, the other engaging pin When the operating member is pressed, the engaging pin is pushed out from the valley of the rack to unlock the sliding member, and the sliding member is pressed at an arbitrary height position to press the operating member when the operating member is pressed. When released, the engaging pin is pushed back by the pin guide, and any engaging pin is engaged with the nearest valley and locked.

することができるうえで好ましい。[0010] The rack member is formed by combining a pair of synthetic resin parts which are divided into two parts in the axial direction, and a square groove-shaped recess is formed in the mating surface of these parts. A rack hole is formed vertically on the inner side surface of the place, and a rack in which valleys and ridges are alternately arranged on one side edge of the rack hole is formed. If a rectangular tubular sliding member is slidably inserted into the bracket, the members constituting the rack and the sliding support of the sliding member of the elbow pad can be achieved by a single member. This is preferable because the strut portion for supporting the elbow pad can be configured to be thinner so that the appearance design of the chair can be further reduced.
