- the engaging groove 22 is formed by an upper surface 22a and a lower surface 22b.
- an elongated hole 26 is formed between the two engaging grooves 22 of the base member 20.
- the sliding rod 42 is inserted into the elongated hole 26. As a result, the sliding rod 42 does not come into contact with the base member 20 even if the support member 40 moves up and down. Therefore, the base member 20 does not hinder the movement of the sliding rod 42.
- the engaging portions 44 of the support member 40 are respectively engaged with the engaging grooves 22.
- the support member 40 operates in conjunction with the rotation (tilt operation) of the display 2 (base member 20).

Will move up and down. Further, when the rotation (tilt operation) of the display 2 (base member 20) is stopped, the operation of the support member 40 is suppressed by the frictional force caused by the compressive force of the suppressing member 50 to shrink the hole 52. Therefore, the support member 40 supports the base member 20 so that the display 2 stands still at the stopped angle. In this way, the angle adjusting mechanism 10 according to the first embodiment realizes a free stop function in which the angle (tilt) of the display 2 can be manually changed.

- it receives compressive force.
- the compressive force (repulsive force) of the restraining member 50 which is an elastic material, is applied only to the sliding rod 42 of the supporting member 40. Therefore, the repulsive force of the restraining member 50 suppresses the load on the surrounding parts. Therefore, the angle adjusting mechanism 10 according to the first embodiment can suppress the influence of the frictional force for holding the angle of the display 2 on the surrounding parts.
- the support member 40 (sliding rod 42) is made of a molded part having relatively high rigidity. Therefore, it is extremely unlikely that the support member 40 will be deformed by the compressive force of the restraining member 50. Further, since the support member 40 is formed of a molded component having high rigidity instead of an elastic material, the repulsive force of the support member 40 with respect to the base member 20 is hardly generated. Then, the weights of the display 2 and the base member 20 are all applied to the support member 40. As described above, the repulsive force of the suppressing member 50 is applied only to the support member 40 and is not transmitted to other members, and the support member 40 hardly generates the repulsive force, so that the base member 20 is hardly loaded. Therefore, it is possible to prevent the load from being applied to the surrounding parts such as the rotating shaft 16.

That is, when the support member 40 is press-fitted into the hole 52 of the restraining member 50, not only the inside of the hole 52 but also the outside can be deformed. Therefore, a repulsive force may be generated around the restraining member 50.
- the repulsive force that may be generated outside the restraining member 50 is suppressed from being transmitted to the mount member 30. can do. Therefore, it is possible to suppress the influence of the repulsive force that may be generated around the suppressing member 50 on the surrounding parts.
- grooves are formed in the vertical direction at equal intervals around the sliding rod 42.
- grooves are formed at equal intervals along the sliding direction of the support member 40 and at positions symmetrical with each other when viewed from the axial direction of the sliding portion. It is formed. Since the sliding rod 42 is formed in this way, the force (repulsive force) applied to the sliding rod 42 is narrowed down to a symmetrical position where the sliding rod 42 contacts the inner wall of the hole 52 of the restraining member 50. ) Can be suppressed.
- the repulsive force applied to the sliding rod 42 is biased by limiting the location where the repulsive force is applied to symmetrical positions over the entire circumference. Can be suppressed.

Therefore, the inclination of the display 2 is maintained at an angle as shown in the state B.
- the user manually rotates the display 2 (base member 20) further upward to enter the state C.
- the support member 40 is moving upward.
- the support member 40 is prevented from falling downward due to the repulsive force of the restraining member 50 (friction force between the restraining member 50) even if the display 2 and the base member 20 receive their own weight. Therefore, the inclination of the display 2 is maintained at an angle as shown in the state C. In this way, when the user manually rotates the display 2 (base member 20) upward, the inclination of the display 2 can be adjusted so as to have an arbitrary angle.
- the user manually rotates the display 2 (base member 20) downward to enter the state B.
- the engaging portion 44 of the support member 40 is hooked on the engaging groove 22, and the upper surface 22a of the engaging groove 22 presses the engaging portion 44 downward, so that the state is changed from the state C.
- the support member 40 is moving downward.
- the support member 40 is prevented from falling downward due to the repulsive force of the restraining member 50 (friction force between the restraining member 50) even if the display 2 and the base member 20 receive their own weight. .. Therefore, the inclination of the display 2 is maintained at an angle as shown in the state B.
- the user manually rotates the display 2 (base member 20) further downward to enter the state A.
- the support member 40 is moving downward.
- the support member 40 is prevented from falling downward due to the repulsive force of the restraining member 50 (friction force between the restraining member 50) even if the display 2 and the base member 20 receive their own weight. Therefore, the inclination of the display 2 is maintained at an angle as shown in the state A. In this way, when the user manually rotates the display 2 (base member 20) downward, the inclination of the display 2 can be adjusted so as to have an arbitrary angle.
- the support member 40 according to the first embodiment is formed in a T shape.
- the T-shaped vertical bar corresponds to the sliding bar 42
- the T-shaped horizontal bar corresponds to the engaging portion 44.
- the support member 40 in a T shape, the range of points where the support member 40 and the base member 20 come into contact with each other when the support member 40 moves up and down can be made constant. Therefore, it is possible to suppress a large change in the load required to rotate the display 2. Therefore, good operability can be realized by a simple structure of T-shape. Further, by making the shape of the engaging portion 44 cylindrical, it is possible to prevent the contact point between the support member 40 and the base member 20 from changing discontinuously when the support member 40 moves up and down. Therefore, it is possible to prevent the load required for rotating the display 2 from changing discontinuously. Therefore, even better operability can be realized.
- the angle adjusting mechanism according to the comparative example is different from the angle adjusting mechanism 10 according to the first embodiment in that the silicon rubber member is sandwiched between the sliding surfaces between the base member and the mount member.
- FIG. 15 is a perspective view showing the angle adjusting mechanism 90 according to the comparative example.
- FIG. 16 is a diagram showing details (a portion surrounded by an ellipse in FIG. 15) of the angle adjusting mechanism 90 according to the comparative example.
- the angle adjusting mechanism 90 according to the comparative example has a base member 920 to which the display 2 is attached, a mounting member 930, and an elastic member 940.
- the base member 920 is rotatably connected to a rotation shaft 916 provided on the mount member 930.
- the base member 920 has substantially the same structure as the guide rib 24 according to the first embodiment.
- the mount member 930 has substantially the same structure as the guide groove 34 according to the first embodiment.
- FIG. 17 is a perspective view showing an elastic member 940 according to a comparative example.
- FIG. 18 is a cross-sectional view showing the vicinity of the elastic member 940 of the angle adjusting mechanism 90 according to the comparative example.
- the elastic member 940 is formed in a cylindrical shape. Further, the elastic member 940 is made of, for example, silicon rubber.
- the elastic member 940 is sandwiched between the sliding surfaces 910 between the base member 920 and the mount member 930. When the elastic member 940 is compressed by the base member 920 and the mount member 930, a frictional force is generated between the elastic member 940 and the base member 920 and the mount member 930. By this frictional force, the user can adjust the inclination of the display 2 (base member 920) to be an arbitrary angle.
- the base member 920 operates against the frictional force generated by the elastic member 940. Then, when the rotation of the display 2 (base member 920) is stopped, the inclination of the base member 920 is maintained by the frictional force of the elastic member 940 at the inclination when the display is stopped.
- the elastic member 940 since the elastic member 940 is compressed, a repulsive force is generated by the elastic member 940 in the direction in which the base member 920 and the mount member 930 are separated from each other, as shown by arrows D in FIGS. 16 and 18. As a result, a load is applied to the rotating shaft 916 connecting the base member 920 and the mount member 930 as shown by the arrow E in FIG.
- the rotating shaft 916 since the rotating shaft 916 is thin, its rigidity is weak. When a load is applied to such a component having low rigidity, the component may be deformed. Therefore, in the angle adjusting mechanism 90 according to the comparative example, the frictional force for holding the angle of the display may affect the surrounding parts. Further, the force for rotating the display 2 (rotational force) may vary, and the user may not be able to adjust the angle well. Therefore, the quality of the angle adjusting mechanism 90 according to the comparative example may not be stable.
- the angle adjusting mechanism 10 according to the first embodiment described above is configured such that the repulsive force of the restraining member 50, which is an elastic member, is applied only to the sliding rod 42 of the supporting member 40.
- the repulsive force of the restraining member 50 is not transmitted to the surrounding parts. That is, the influence of the frictional force of the suppressing member 50 is applied only to the supporting member 40, and is suppressed from reaching the surrounding parts. Therefore, the angle adjusting mechanism 10 according to the first embodiment can suppress the influence of the frictional force for maintaining the angle of the display on the surrounding parts. Further, it is possible to suppress variations in the force (rotational force) for rotating the display 2. Therefore, the angle adjusting mechanism 10 according to the first embodiment can realize stable quality as compared with the angle adjusting mechanism 90 according to the comparative example.
- the support member 40 does not have to be T-shaped. Any shape may be used as long as it can be moved up and down in conjunction with the rotation of the display 2.

図11は、実施の形態1にかかる角度調整機構10の組み立て方法を示すフローチャートである。まず、マウント部材30に抑制部材50を取り付ける(ステップS12)。具体的には、マウント部材30の収容部32に、抑制部材50を挿入する。次に、抑制部材50に支持部材40を取り付ける(ステップS14)。具体的には、抑制部材50の穴52に、支持部材40の一部である摺動棒42を挿入(圧入)する。
図12及び図13は、実施の形態1にかかる角度調整機構10によって表示器2が回転した状態を示す図である。図12は、角度調整機構10の斜視図を示す。図13は、角度調整機構10の側面図を示し、矢印Cで示す二点鎖線で囲まれた箇所は、支持部材40及び抑制部材50の断面を示す。また、図14は、図13における支持部材40及び抑制部材50の断面の拡大図である。
