It has a part 5f). The plurality of first protrusions 5f extend in the mounting direction.

When viewed from the mounting direction, at least one (for example, all) of the first protrusions 5f has a contour that tapers outward (for example, an ellipse or a perfect circular arc). It has a parabolic shape or a contour such as a substantially triangular shape). The first protruding portion 5f comes into contact with the inner peripheral surface of the first inserting portion 6b at the tip end portion of this contour.

When viewed from the mounting direction, the contour of the first boss portion 5d excluding the first protruding portion 5f is a perfect circle. Further, when viewed from the depth direction of the first insertion portion 6b, the contour of the inner peripheral surface of the first insertion portion 6b is a perfect circle.

When viewed from the mounting direction, the pair of first protruding portions 5f among the plurality of first protruding portions 5f is on the virtual line Y passing through the center Q1 of the first boss portion 5d or within ± 15 ° with respect to the virtual line Y. They are arranged on lines that are inclined at an angle of the range (here, on the virtual line Y as an example). Further, the virtual line Y is inclined at an angle θ in a predetermined range with respect to the tilting direction, and is directed to the above-mentioned crossing direction.

As a result, even when an external force is applied to the first boss portion 5d from the inner peripheral surface of the first insertion portion 6b in the tilting direction during the operation of the switch device 1, the external force is applied in the protruding direction of the first protruding portion 5f. Only the component force of is transmitted to the first protrusion 5f. Therefore, the force acting on the first protruding portion 5f in the protruding direction is reduced. As a result, the operation of the switch device 1 prevents the first protrusion 5f from being crushed.

In the present embodiment, the above-mentioned predetermined range is a range of 30 ° or more and 60 ° or less. As the value in this predetermined range, for example, a value in the range of 35 ° or more and 55 ° or less is more preferable, and a value in the range of 40 ° or more and 50 ° or less is more preferable.

The second boss portion 5e is formed in a substantially columnar shape as a whole. The second boss portion 5e is a pair of protruding portions (second protrusions) protruding from the peripheral surface of the second boss portion 5e along the tilting (Z) direction of the second boss portion 5e when viewed from the mounting (longitudinal) direction. Part 5g). The plurality of second protrusions 5g extend in the mounting direction.

When viewed from the mounting direction, at least one (here, both) of the second protrusions 5g of the pair of second protrusions 5g has a contour that tapers outward (for example, an ellipse or a perfect circular arc, a parabola). It has a shape or an outline such as a substantially triangular shape). The second protruding portion 5g comes into contact with the inner peripheral surface of the second inserting portion 6c at the tip portion of this contour.

When viewed from the mounting direction, the contour of the second boss portion 5e excluding the second protruding portion 5g is circular as a whole, but in order to prevent interference between the second boss portion 5e and the window portion 5b, the second boss The portion of the portion 5e that overlaps with the window portion 5b is cut out. Further, when viewed from the depth direction of the second insertion portion 6c, the contour of the inner peripheral surface of the second insertion portion 6c is substantially elliptical with the tilting direction as the minor axis direction and the axis X direction as the major axis direction. As described above, the second insertion portion 6c is formed as an elongated hole.

The number of the second protruding portions 5g in the second boss portion 5e is smaller than the number of the first protruding portions 5f in the first boss portion 5d. Therefore, the second boss portion 5e is easier to insert into the second insertion portion 6c than when the first boss portion 5d is inserted into the first insertion portion 6b.

Further, the second protruding portion 5g is arranged along the minor axis direction of the second inserting portion 6c when viewed from the mounting direction. Therefore, it is possible to slightly adjust the relative positions of the second boss portion 5e and the second insertion portion 6c along the long axis direction of the second insertion portion 6c.

In the operating body 4, the first boss portion 5d is press-fitted into the first insertion portion 6b in a state where the first protrusion 5f is in contact with the inner peripheral surface of the first insertion portion 6b, and the second protrusion 5g is the second insertion portion. The operation portion 6 is fixed to the base portion 5 by press-fitting the second boss portion 5e into the second insertion portion 6c in a state of being in contact with the inner peripheral surface of the 6c.

When viewed from the direction perpendicular to the mounting direction, the overlapping length dimension Wa of the first boss portion 5d and the first insertion portion 6b in the mounting direction is larger than 1/2 of the length dimension Ln of the first boss portion 5d. It is set to a value (see FIGS. 5 and 6). Similarly, when viewed from the direction perpendicular to the mounting direction, the overlapping length dimension Wa of the second boss portion 5e and the second insertion portion 6c in the mounting direction is 1/2 of the length dimension Ln of the second boss portion 5e. Is set to a value larger than.

In this way, by ensuring a long overlap length dimension Wa between the boss portions 5d and 5e and the corresponding insertion portions 6b and 6c, the base portion 5 and the operation unit 6 when the switch device 1 is used can be used. The change in the relative position of the above is suppressed, and the occurrence of rattling between the base portion 5 and the operation portion 6 is prevented.

Further, as shown in FIGS. 1, 3 and 4, the operation portion 6 is provided with a pair of claw portions, and the base portion 5 is provided with a pair of engagement portions. In the present embodiment, a pair of claw portions 6d are provided on each of the one end side and the other end side in the longitudinal direction of the operation portion 6, and a pair of claw portions 6d are provided on each of the one side and the other side in the axis X direction of the base portion 5. An engaging portion 5h is provided.

Each of the claw portions 6d in the pair of claw portions 6d is arranged side by side in the tilting direction in the operation portion 6. Further, the respective engaging portions 5h in the pair of engaging portions 5h are arranged side by side in the tilting direction in the base portion 5. In the switch device 1, in a state where the boss portions 5d and 5e are press-fitted into the insertion portions 6b and 6c, the claw portion 6d and the engaging portion 5h engage with each other, so that the operating portion 6 is twisted with respect to the base portion 5. It is securely fixed.

The pair of claw portions 6d extend toward the base portion 5. In the present embodiment, the pair of claw portions 6d extends from the main body of the operation portion 6 toward the base portion 5, and then protrudes outward in the tilting direction. The pair of claw portions 6d can be bent inward in the tilting (width) direction of the operating portion 6. When viewed from the axis X direction, the pair of claw portions 6d has a shape symmetrical with respect to a line extending through the center of the axis X and along the longitudinal direction of the pair of claw portions 6d. A return (wedge) portion 6e is formed on the tip end side of the claw portion 6d by rapidly increasing the width dimension of the claw portion 6d from the root side to the tip side of the claw portion 6d. Further, a tapered surface 6f is formed on the tip end side of the claw portion 6d.

The engaging portion 5h engages with the pair of claw portions 6d. The base portion 5 is provided with a guide surface 5i. The guide surface 5i is in a state where the boss portions 5d and 5e are partially inserted into the insertion portions 6b and 6c from the tip side (in other words, the boss portions 5d and 5e are inserted in the portion having the length dimension Wb from the tip side. In the state of being partially inserted into the portions 6b and 6c), the boss portions 5d and 5e are guided to the inside of the insertion portions 6b and 6c by relatively moving while contacting the tapered surfaces 6f of the pair of claw portions 6d. .. An engaging portion 5h with which the return portion of the claw portion 6d engages is formed on the back side of the insertion hole 5c in the insertion direction of the claw portion 6d (see FIGS. 5 and 6).

As an example, when viewed from the mounting direction, the pair of claw portions 6d are arranged side by side in the tilting direction with the center of the boss portions 5d and 5e interposed therebetween. Further, the tapered surface 6f is arranged outside the tilting direction of each claw portion 6d.

Here, the pair of claw portions 6d provided in the operation portion 6 of the present embodiment extends from the vicinity positions of the insertion portions 6b and 6c toward the base portion 5. In the present embodiment, the portion near the insertion portions 6b and 6c in the operation portion 6 is relatively less deformed by inserting the boss portions 5d and 5e into the insertion portions 6b and 6c. Therefore, when viewed from the mounting direction, of the two pairs of claw portions 6d, the pair of claw portions 6d are arranged near the first insertion portion 6b, and the remaining pair of claw portions 6d is the second insertion portion. It is arranged in the vicinity of 6c.

As a result, when the operating body 4 is assembled or the switch device 1 is used, the claw portion 6d is prevented from being damaged by suppressing the deformation of the claw portion 6d due to an external force applied to the root portion of the claw portion 6d. There is.

The "nearby position" is, for example, a value in the range where the shortest distance between the inner peripheral surfaces of the insertion portions 6b and 6c and the claw portion 6d adjacent to each inner peripheral surface is within 0.5 mm or more and 0.7 mm or less. However, it is not limited to this.

FIG. 5 is a cross-sectional view of the operating portion 6 before engaging with the base portion 5 of FIG. FIG. 6 is a cross-sectional view of the operating portion 6 after being engaged with the base portion 5 of FIG. As shown in FIG. 5, when assembling the operating body 4, the operator first inserts the tip of the first boss portion 5d of the base portion 5 into the first insertion portion 6b, and inserts the tip of the second boss portion 5e into the first insertion portion 6b. 2 Insert into the insertion portion 6c. At this time, the operator performs the work while aligning the longitudinal direction of the boss portions 5d and 5e with the depth direction of the insertion portions 6b and 6c.

Here, the first protruding portion 5f formed on the peripheral surface of the first boss portion 5d comes into contact with the inner peripheral surface of the first insertion portion 6b, so that the first boss portion 5d is press-fitted into the first insertion portion 6b. Begin to be done. Further, the second protruding portion 5g formed on the peripheral surface of the second boss portion 5e comes into contact with the inner peripheral surface of the second insertion portion 6c, so that the second boss portion 5e is press-fitted into the second insertion portion 6c. start.

Further, the operator inserts the pair of claw portions 6d into the insertion hole 5c with the boss portions 5d and 5e partially inserted into the corresponding insertion portions 6b and 6c from the tip side, and inserts the tapered surface 6f into the guide surface 5i. To make contact with. At this time, the boss portions 5d and 5e are partially inserted into the insertion portions 6b and 6c at the portion of the length dimension Wb from the tip end side. The length dimension Wb is set to a value of 0.5 mm or more as an example.

As a result, the boss portions 5d and 5e are positioned with respect to the insertion portions 6b and 6c by the inner peripheral surfaces of the insertion portions 6b and 6c, and the pair of claw portions 6d guide the engaging portions 5h with the tapered surface 6f. Positioned by the surface 5i.

The operator advances the insertion of the first boss portion 5d into the first insertion portion 6b and the insertion of the second boss portion 5e into the second insertion portion 6c. As a result, as shown in FIG. 6, the boss portions 5d and 5e are inserted into the corresponding insertion portions 6b and 6c from an appropriate direction while the posture of the operation portion 6 with respect to the base portion 5 is kept stable. Further, when the claw portion 6d is bent while being guided by the guide surface 5i on the tapered surface 6f, unnecessary deformation of the claw portion 6d is suppressed and damage to the claw portion 6d is prevented.

Further, in the first boss portion 5d and the first insertion portion 6b, the overlapping length dimension Wa is set to a value larger than 1/2 of the length dimension Ln of the first boss portion 5d, and the second boss is set. In the portion 5e and the first insertion portion 6b, the overlapping length dimension Wa is set to a value larger than 1/2 of the length dimension Ln of the second boss portion 5e, so that the claw portion 6d is stable. It is guided toward the engaging portion 5h in the posture, and the claw portion 6d is appropriately bent to be engaged with the engaging portion 5h.

Further, as shown in FIG. 4, in the present embodiment, when viewed from the depth direction of the second insertion portion 6c, the peripheral surface of the second insertion portion 6c has the axis X direction as the major axis direction and the tilt direction as the minor axis. It is formed in the shape of an elongated hole in the direction. As a result, the second boss portion 5e and the second insertion portion 6c can be slightly moved relative to each other in the axis X direction.

Therefore, for example, after a part of the tip of the first boss portion 5d is inserted into the first insertion portion 6b to determine the relative position between the base portion 5 and the operation portion 6 to some extent, the tip of the second boss portion 5e is seconded. It can be properly inserted into the insertion portion 6c.

The first boss portion 5d is completely inserted into the first insertion portion 6b, the second boss portion 5e is completely inserted into the second insertion portion 6c, and each of the two pairs of claw portions 6d is with the engaging portion 5h. By engaging, the fixing of the operation portion 6 to the base portion 5 is completed.

As described above, according to the switch device 1, the first boss portion 5d is in contact with both the outer peripheral surface of the first boss portion 5d and the inner peripheral surface of the first insertion portion 6b. By being press-fitted into the first insertion portion 6b, the operation portion 6 is fixed to the base portion 5, so that the operation portion 6 can be reliably fixed to the base portion 5. Therefore, it is possible to prevent the operation feeling of the operation unit 6 from being impaired.

Further, since the plurality of first protruding portions 5f project in the intersecting direction intersecting both the tilting direction of the base portion 5 and the axis X direction when viewed from the mounting direction, the operator operates the operating portion 6 to base the base. The compressive stress acting on the first protruding portion 5f when the portion 5 is tilted can be reduced. As a result, the crushing of the first protruding portion 5f can be suppressed, and the operating portion 6 can be stably fixed to the base portion 5 for a long period of time. Therefore, the durability of the switch device 1 can be improved.

Further, when viewed from the mounting direction, at least a pair of first protruding portions 5f among the plurality of first protruding portions 5f are on the virtual line Y passing through the center of the first boss portion 5d or ± 15 ° with respect to the virtual line Y. Each is arranged on a line inclined at an angle within a range, and the virtual line Y is inclined at an angle within a predetermined range with respect to the tilting direction of the base portion 5 and is directed to the above-mentioned crossing direction. By arranging the pair of first protrusions 5f in this way, the compressive stress acting on the pair of first protrusions 5f when the operation portion 6 is operated to tilt the base portion 5 is reduced, while reducing the compressive stress. It is possible to prevent the compressive stress from concentrating on the specific first protrusion 5f.

Further, since the above-mentioned predetermined range is a range of 30 ° or more and 60 ° or less, the compressive stress acting on the pair of first protrusions 5f when the operation portion 6 is operated to tilt the base portion 5 is further improved. Can be reduced to.

Further, since the plurality of protruding portions 5f and 5g extend in the mounting direction, the boss portions 5d and 5e can be easily fixed to the insertion portions 6b and 6c over a wide range in the mounting direction of the boss portions 5d and 5e. ..

Further, when viewed from the direction perpendicular to the mounting direction, the overlapping length dimension of the boss portions 5d, 5e and the insertion portions 6b, 6c in the mounting direction is larger than 1/2 of the length dimension of the boss portions 5d, 5e. Since the value is set, the boss portions 5d and 5e can be stably supported by the inner peripheral surfaces of the insertion portions 6b and 6c over a wide range in the mounting direction of the boss portions 5d and 5e.
