固定してある。That is, the semicylindrical inner bearing portion 22 (see 22 in FIG. 6) is formed at the lower end of the front cover 1 ', and the meter case 3'is formed.
Semi-circular outer bearing pieces 23, 23 facing the inner bearing portion 22 are formed on the left and right sides at the lower end of the. Here, the meter case 3'is fixed by fitting the locking claw pieces 25 equally arranged on the circumference thereof into the engaging grooves 26 of the inner circumference of the front cover 1 '. Then, on the upper end of the counter cover 2 ', a bearing guide piece 24 (see 24 in FIG. 6) which is slidably fitted between the inner bearing portion 22 and the outer bearing portion 23 is formed. Here, the counter cover 2'is fixed to the casing 4'by screws 27.

タがもろにヒンジ部21のガタとなって現れるのである。However, the above-mentioned hinge structure has a drawback that the play of the hinge becomes large due to dimensional variations in manufacturing. That is, in FIG. 7, the radius of the inner support portion 22 is f 1 , the inner radius of the outer support piece 23 is f 2 , the center position of f 1 is h 1 , the center position of f 2 is h 2 , and the locking claw is When the backlash between the piece 25 and the engaging groove 26 is s, the hinge fitting dimension x = (f 2 −
As shown by f 1 ) + (h 1 −h 2 ) + s, the dimensional variation of the inner support portion 22 and the outer support piece 23 and the backlash of the locking claw piece 25 appear as backlash of the hinge portion 21. Of.

In Japanese Patent No. 42370, as shown in FIG. 9, a hook portion for catching the inner bearing portion 28 and the bearing guide piece 29 is used.
Forming 30,31. However, in this hinge structure, there is no choice but to form the hole 32 for forming the hook on the bearing guide piece 29 made of synthetic resin.
Therefore, there was a problem that water etc. from the car infiltrated into the instrument.

〔考案が解決しようとする課題〕[Problems to be solved by the device]

本考案は、上記した点に鑑み、ヒンジ部のガタをなく

め溝に係合する突条が形成されたことを特徴とする。In order to achieve the above object, the present invention provides a semi-cylindrical inner bearing portion formed on a front cover, an outer bearing portion that faces the outside of the inner bearing portion, and a counter cover. In a hinge structure of a travel recorder including a semi-cylindrical bearing guide engaged between the outer portion and the outer bearing portion, the outer bearing portion is integrally formed with the front cover, and the outer bearing portion is formed. Is formed in a semicircular shape concentric with the inner bearing portion, and a semicircular swing groove is formed between the outer bearing portion and the inner bearing portion. The entire surface is capable of contacting the entire outer diameter portion of the bearing guide, and a circumferential positioning groove is formed in the outer diameter portion of the bearing guide, and the positioning groove is engaged with the inner diameter portion of the outer bearing portion. It is characterized in that a ridge is formed.

〔作用〕[Action]

内側支承部と外側支承部とが前面カバーに対して一体

する。Since the inner bearing portion and the outer bearing portion are formed integrally with the front cover, the dimensional accuracy of the swing groove is extremely good. Further, since the outer bearing portion is formed on the front cover, it is not affected by the backlash of the meter case as in the conventional case. In addition, when the front cover is closed, the outer bearing part comes into full contact with the bearing guide, and the bearing guide is completely wrapped in the outer bearing part and held in the swing groove without rattling.
Even when the cover is opened and closed, the outer bearing stably contacts the bearing guide over a large area. Further, the ridges of the outer support portion engage with the positioning grooves of the support guide to restrict the lateral movement of the front cover in the lateral direction orthogonal to the rotation direction thereof and prevent rattling.

できる。That is, in the hinge structure of the present invention, the semi-cylindrical inner bearing portion 5 is formed at the lower end of the front cover 1 made of synthetic resin, and the semi-circular inner diameter portion 6a is concentric with the inner bearing portion 5. Outer bearing pieces 6,6 are integrally formed with the inner bearing portion 5 on the left and right of the front cover 1, and a semicircular swing groove is formed between the inner bearing portion 5 and the outer bearing pieces 6,6. 7 and 7, the upper end of the counter cover 2 is formed with arcuate bearing guide pieces 8 and 8 which fit into the swing grooves 7 and 7. Here, the positioning groove 8a is cut out in one of the bearing guide pieces 8, and the positioning groove 8a is formed in the one outer bearing piece 6.
A ridge 6b is formed so as to be fitted to. Also, the outer support piece
6, 6 can be formed by a slide method of a molding die.

Are fixed by fitting the locking claw pieces 11 evenly arranged on the circumference thereof into the engaging grooves 12 on the inner circumference of the front cover 1.
Further, a hollow reinforcing rib 13 is integrally formed on the outer supporting piece 6, and a fitting rib 14 that fits into the reinforcing rib 13 is formed on the meter case 3. On the other hand, the counter cover 2 is fixed to the casing 4 with screws 15.

図で、16は、第３図に示すようにメータ部Ｍを開いた
際にストッパとして働くＴバーであり、該Ｔバー16の一
端はメータケース３の蟻溝17に、他端はケーシング４に
夫々遊嵌している。In the figure, 16 is a T-bar that acts as a stopper when the meter portion M is opened as shown in FIG. 3, one end of the T-bar 16 is in the dovetail groove 17 of the meter case 3, and the other end is the casing 4 Are fitted to each other.

本実施例によれば、第４図にヒンジ部の要部断面を示
すように、内側支承部５と外側支承片６とは一体に成形
されているから、内側支承部５の半径ｆ1と外側支承片
６の内半径ｆ2との差（ｆ2−ｆ1）＝一定、また、内側
支承部５の中心位置ｈ1と外側支承片６の中心位置ｈ2と
が同一であるから、ｈ1−ｈ2＝０、さらに、従来と違っ
てメータケース３に外側支承片６を設けていないから、
係止爪片11のガタｓ（第２図参照）はヒンジ構造に無関
係であり無視できる。従って、ヒンジ嵌合寸法ｘ＝（ｆ
2−ｆ1）＋（ｈ1−ｈ2）＋ｓ＝一定となり、ガタのない
安定した寸法のヒンジ構造を得ることができる。According to this embodiment, as shown in the cross section of the main part of the hinge portion in FIG. 4, since the inner bearing portion 5 and the outer bearing piece 6 are integrally molded, the radius f 1 of the inner bearing portion 5 is the difference between the inner radius f 2 of the outer bearing piece 6 (f 2 -f 1) = constant, also because the center position h 2 of the center position h 1 and the outer bearing piece 6 of the inner bearing 5 are the same, h 1 −h 2 = 0, and unlike the conventional case, since the outer supporting piece 6 is not provided in the meter case 3,
The backlash s (see FIG. 2) of the locking claw piece 11 is irrelevant to the hinge structure and can be ignored. Therefore, the hinge fitting dimension x = (f
2− f 1 ) + (h 1 −h 2 ) + s = constant, and it is possible to obtain a hinge structure with a stable size without play.

第５図は、本考案のヒンジ構造におけるストッパ（第
２図の16）の変形例を示すものである。FIG. 5 shows a modification of the stopper (16 in FIG. 2) in the hinge structure of the present invention.

ガイド片8aが形成されていることは言うまでもない。This stopper structure is mainly applied to a square operation recorder, and the front cover 1a is attached to the inner wall of the casing 4a.
The arc-shaped guide groove 18 having an angle corresponding to the opening degree of the arc-shaped arm 1 having the claw portion 19a which is slidable by being fitted into the guide groove 18 with respect to the front cover 1a.
It is formed by projecting 9. Then, when opened, the claw portion 19a comes into contact with the end surface 18a of the guide groove 18 and stops. Needless to say, the front cover 1a is integrally formed with the inner bearing portion 5a and the outer bearing piece 6c, and the counter cover 2a is formed with the bearing guide piece 8a.

The dimensional accuracy of the rocking groove is extremely good, and the outer bearing is formed on the front cover instead of the conventional meter case.
There is no influence of backlash between the meter case and the front cover unlike the conventional case. In addition, when the front cover is closed, the outer bearing portion comes into full contact with the bearing guide, and the outer bearing portion stably contacts the bearing guide over a large area even while the cover is being opened or closed. These prevent looseness of the hinge part, prevent the heavy cover (including the meter part) from coming off, and prevent water from entering the instrument due to looseness, and also ensure stable rotation operation. You can do it. Also, due to the engagement between the positioning groove of the bearing guide and the protrusion of the outer bearing,
It is also possible to prevent backlash in the lateral direction orthogonal to the rotating direction of the front cover.
