を提供することを目的とする。However, in the conventional integrating meter, since the push members are held at the upper and lower two places, it is necessary to engage the push members with the upper and lower two places at the time of assembly. In addition, since the pushing member is supported at two points, it is difficult to obtain the degree of freedom when assembling, and the pushing shaft for moving the pushing member up and down through the hole such as the front glass of the meter case is penetrated, and the pushing shaft returns to zero. When the operation is performed, if the position of the push shaft and the position of the hole of the front glass are displaced, the hole of the front glass and the push shaft interfere with each other, which causes a problem that the push shaft is not properly returned. The present invention has been made in view of the above points,
It is an object of the present invention to provide an integrating meter which is easy to assemble and has a high degree of freedom in assembling.

いる。In FIG. 4, reference numeral 1 denotes a pushing member, which is made of resin or the like and is engaged with and held by a holding member 2 which is a machine frame. Like the pushing member 1, the holding member 2 is made of resin or the like, and is fixed to the integrating meter body 4 with a screw 3. The holding member 2 has a column portion 2a for guiding the pushing member 1 shown in FIGS. 2 and 3, a convex portion 2b for preventing the pushing member 1 from coming off shown in FIG. 1, and an engaging portion for giving a moderation feeling during operation. 2c is integrally formed.

押し込む。Further, the pushing member 1 is made of resin and has a hole portion 1a which engages with the column portion 2a as shown in FIGS. 2 and 3, and an arm portion 1c having a claw portion 1b at its tip as shown in FIG. A pressing portion 1d for performing the zero-return operation is integrally formed. A coil spring 5 as an urging means is attached to the column 2a of the holding member 2, and the hole 1a of the pressing member 1 fits the column 2a while compressing the coil spring 5. When the push member 1 is assembled to the holding member 2, the push member 1 is pushed in the direction of arrow A.

むことにより押部材１が押し込まれる。When the pushing member 1 is pushed in, first, the claw portion 1b provided at the tip of the arm portion 1c of the pushing member 1 comes into contact with the convex portion 2b of the holding member 2, and when it is pushed further in, the arm portion 1 of the pushing member 1 is pushed.
c bends in the direction of arrow C, the claw portion 1b rides over the convex portion 2b, and the claw portion 1b engages with the convex portion 2b. At this time, the pushing member 1 is biased by the coil spring 5 in the direction of the arrow B, and when the pushing member 1 is not pushed in, the claw portion 1b.
Engages with the convex portion 2b to hold the pushing member 1 on the holding member 2 as shown in FIGS. 1 (B) and 2. A push shaft 6 for performing an operation is engaged with the push member 1, and the push member 1 is pushed in by pushing the push shaft 6.

Push in. When the push shaft 6 is pushed in, the push member 1 moves in the direction of arrow A against the coil spring 5. While the pushing member 1 is moving in the direction of the arrow A, first, the arm portion 1c is moved to the engaging portion 2c.
Hit The arm portion 1c bends in the direction of arrow D by the engaging portion 2c, gets over the engaging portion 2c, and engages with the engaging portion 2c as shown in FIG. 1B.

る。At this time, when the pushing member 1 is pushed in the direction of arrow A, the pushing portion 1d pushes the heart cam 8 engaged through the return lever 9, and the numeral wheel 7 formed integrally with the heart cam 8 is zeroed. To be done. Since these configurations are well known and are not directly related to the present invention, description thereof will be omitted.

に行なわれたことがわかる。When the pushing down of the pushing shaft 6 is stopped, the pushing member 1 is pushed up by the restoring force of the coil spring 5,
(A), returns to the initial state shown in FIG. In this way, when the push member 1 is pushed down by the push shaft 6, the arm 1
After c hits the engaging portion 2c, it is flexibly engaged. At this time, a feeling of moderation can be obtained, so it can be seen that the zero-return operation is reliably performed.

係合した押部材１が確実に押し込まれる。従って、確実
に帰零動作を行なうことができる。Further, when the zero return operation is performed, the push shaft 6 is pushed in,
When the arm portion 1c of the pushing member 1 gets over the engaging portion 2c of the holding member 2, the pushing force of the pushing shaft 6 becomes strong, and after getting over, it becomes weak. Therefore, the force for pushing the push shaft 6 rapidly changes from strong to weak, so that the pushing member 1 engaged with the push shaft 6 is surely pushed by its inertia. Therefore, the zero-return operation can be surely performed.

【００１４】また、押部材１の保持部材２への組付けは
一方向から強圧すればよいため、組立作業が容易にな
り、自動組付も可能となる。Further, since the pressing member 1 can be assembled to the holding member 2 by applying strong pressure from one direction, the assembling work is facilitated and the automatic assembling is also possible.

零動作後の押し軸６の戻り不良となりにくい。Further, the pushing member 1 is composed of the supporting column 2 of the holding member 2.
Since the pushing shaft engaged with the pushing member 1 is hardly restrained against falling due to being restrained at only one point of a, the hole portion 10a of the front glass 10 and the pushing shaft 6 are displaced from each other. However, the return failure of the push shaft 6 after the zero-return operation is unlikely to occur.
