However, in the configuration using the sliding load support device as described above, an increase in sliding resistance due to pressing the bullet contact piece against the sliding surface becomes a problem. And since there is a problem that the rattling suppressing effect is limited by this, there is still room for improvement in this respect.

The present invention has been made to solve the above problems, and an object of the present invention is a sliding load capable of more effectively suppressing the occurrence of rattling while suppressing an increase in sliding resistance. The purpose is to provide a support device and a sunroof device.

The sliding load support device for solving the above problems includes a bullet contact piece that elastically slides against the sliding surface in a state of extending along the sliding surface, and the bullet contact piece with respect to the sliding surface. A base end support portion that supports a base end portion of the bullet contact piece separated from the sliding contact portion in the longitudinal direction is provided, and the bullet contact piece is adjacent to the base end portion in the longitudinal direction of the bullet contact piece. The first bending region and the second bending region closer to the sliding contact portion than the first bending region are provided, and the direction in which the bullet contact piece bends due to the input of a load to the sliding contact portion is the bullet contact. As the thickness direction of the piece, the thickness of the bullet contact piece larger than that of the second bending region is set in the first bending region.

According to the above configuration, in the comparison between the first bending region and the second bending region, the second bending region close to the sliding contact portion is more likely to bend than the first bending region. However, when paying attention to the second bending region, the length as the bending region extending in the longitudinal direction of the bullet contact piece, that is, the spring length is shortened, so that the bullet contact piece is pushed against the sliding surface. The reaction force generated by the second bending region becomes larger than the displacement amount of the sliding contact portion caused by the contact, that is, the pressing amount of the bullet contact piece. Further, when the amount of the elastic contact piece pressed against the sliding surface is large, the first bending region on the proximal end side bends together with the second bending region, so that the length as the bending region is secured. NS. As a result, a large reaction force can be obtained with a small pressing amount against the sliding surface, and an excessive reaction force can be prevented even when the pressing amount of the bullet contact piece against the sliding surface is large. can. As a result, it is possible to more effectively suppress the occurrence of rattling while suppressing the increase in sliding resistance.

In the sliding load support device for solving the above problems, the elastic contact piece is subjected to the base from the sliding contact portion side in a bending region in the longitudinal direction in which the elastic contact piece is flexed by inputting a load to the sliding contact portion. It is preferable to provide a thickness gradual change region in which the thickness of the bullet contact piece gradually increases toward the end side.

According to the above configuration, stress can be prevented from being concentrated at the boundary position between the first bending region and the second bending region. As a result, a stable reaction force can be generated according to the amount of the bullet contact piece pressed against the sliding surface, and at the same time, its high reliability can be ensured.

In the sliding load support device that solves the above problems, it is preferable that the thickness gradually changing region is provided in the first bending region.
According to the above configuration, the flexibility of the second bending region can be ensured in comparison with the first bending region. Further, by making the thickness of the bullet contact piece constant in the second flexure region, the bullet contact piece is generated mainly in a situation where the amount of the bullet contact piece pressed against the sliding surface where the second flexure region bends is small. It is possible to design the magnitude of the reaction force with high accuracy. As a result, it is possible to more effectively suppress the occurrence of rattling while suppressing the increase in sliding resistance.

In the sliding load support device that solves the above problems, the bullet contact piece has the sliding contact portion that protrudes toward the sliding surface side from the base end portion and the sliding contact portion that protrudes toward the sliding surface side. It has a curved shape in which the separation distance of the bullet contact piece from the sliding surface gradually increases from the apex position of the portion toward the longitudinal direction of the bullet contact piece and the base end portion side. The curved shape forms a waveform in which the amount of change in the separation distance gradually increases and then gradually decreases from the apex position of the sliding contact portion toward the longitudinal direction of the bullet contact piece and the base end portion side. Is preferable.

According to the above configuration, the bullet contact piece can be brought into sliding contact with the sliding surface at the apex position of the sliding contact portion. Further, based on the curved shape of the waveform, even when the sliding contact portion is pressed against the sliding surface, elastic deformation, that is, bending occurs with respect to the sliding contact portion due to the input of the load. It can be a difficult structure. As a result, the load generated by the sliding contact with the sliding surface can be configured to be input at one point in the longitudinal direction of the bullet contact piece. As a result, by ensuring the length of the flexible region, it is possible to prevent an excessive reaction force from being generated even when the amount of the bullet contact piece pressed against the sliding surface is large.

In the sliding load support device for solving the above problems, it is preferable that the sliding contact portion is provided with a sliding contact protrusion whose tip is in sliding contact with the sliding surface.
According to the above configuration, the load generated by the sliding contact with the sliding surface is input at one point in the longitudinal direction of the bullet contact piece. As a result, it is possible to more effectively suppress the occurrence of rattling while suppressing the increase in sliding resistance.

The sunroof device for solving the above problems includes a movable panel provided in the roof opening of the vehicle, a guide rail extending in the front-rear direction of the vehicle, a sliding member sliding along the longitudinal direction of the guide rail, and the sliding. A support member that opens and closes the movable panel that is supported above the guide rail based on the operation of the moving member, and the guide rail and the sliding member while being supported by one of the guide rail and the sliding member. The sliding load support device according to any of the above, which is in sliding contact with the sliding surface formed by the other, is provided.

That is, in a sunroof device in which a movable panel is opened and closed by sliding a sliding member along a guide rail, the magnitude of the sliding resistance greatly affects the smooth opening and closing operation of the movable panel. Then, the occurrence of rattling becomes a factor that deteriorates the texture. Therefore, according to the above configuration, smoother operation and improvement of texture can be achieved.
In the sunroof device for solving the above problems, the guide rail is provided with a sliding path of the sliding member having a wall portion, and is provided on the sliding member by being supported by the sliding member. It is preferable to provide the sliding load support device that is in sliding contact with the sliding surface formed by the wall portion in a state where the wall portion is sandwiched between the holding portion and the holding portion.

According to the above configuration, it is possible to more effectively suppress the rattling of the sliding member while suppressing the increase in the sliding resistance.

(Bending structure of bullet contact piece)
Next, the bending structure of the bullet contact piece 80 in the sliding load support device 81 of the present embodiment will be described.

As shown in FIG. 15, in the sliding load support device 81 of the present embodiment, the bullet contact piece 80 has the sliding contact portion 80x on the sliding surface S side (upper side in FIG. 15) with respect to the base end portion 80b. It has a protruding curved shape α. Specifically, the bullet contact piece 80 of the present embodiment is in the longitudinal direction (left-right direction in FIG. 15) of the bullet contact piece 80 from the apex position P of the sliding contact portion 80x protruding toward the sliding surface S side. It has a curved shape α such that the separation distance d with respect to the sliding surface S gradually increases toward the base end portion 80b side. Then, in the sliding load support device 81 of the present embodiment, the curved shape α has a sliding surface thereof from the apex position P of the sliding contact portion 80x toward the longitudinal direction of the bullet contact piece 80 and the proximal end portion 80b side. The waveform is such that the amount of change in the separation distance d with respect to S gradually increases and then gradually decreases.

Further, in the sliding load support device 81 of the present embodiment, the sliding contact portion 80x of the bullet contact piece 80 is on the sliding surface S side based on the curved shape αw of the waveform set on the bullet contact piece 80. It has a protruding portion shape that is convex (upper side in FIG. 15). Further, in the bullet contact piece 80 of the present embodiment, even in a state where the sliding contact portion 80x is pressed against the sliding surface S based on the curved shape αw of this waveform, the sliding contact portion 80x has the same respect. The structure is such that elastic deformation due to the input of the load, that is, bending is unlikely to occur. The sliding load support device 81 of the present embodiment has a configuration in which the bullet contact piece 80 is in line contact with the sliding surface S at the apex position P of the sliding contact portion 80x. It has become.

Further, in the sliding load support device 81 of the present embodiment, as described above, the sliding contact portion 80x of the bullet contact piece 80 forms a load input region β in which bending is unlikely to occur, so that the load input region β is larger than the load input region β. In the longitudinal region on the base end portion 80b side, a bending region γ in which the bullet contact piece 80 bends due to the input of a load to the sliding contact portion 80x is formed.

Specifically, the bullet contact piece 80 of the present embodiment has a first bending region γ1 adjacent to the base end portion 80b in the longitudinal direction thereof and a second bending region γ1 closer to the sliding contact portion 80x than the first bending region γ1. It has a region γ2 and. That is, in the bullet contact piece 80 of the present embodiment, the base end portion 80b is supported by the base end support portion 90 so that bending is unlikely to occur. Therefore, the bending region γ in the bullet contact piece 80 of the present embodiment is a longitudinal region between the base end portion 80b and the load input region β. Then, in the sliding load support device 81 of the present embodiment, the direction in which the bullet contact piece 80 bends due to the input of the load to the sliding contact portion 80x is set as the thickness direction of the bullet contact piece 80, and the first bending region γ1 thereof. The thickness D of the bullet contact piece 80, which is larger than the second bending region γ2, is set.

More specifically, in the sliding load support device 81 of the present embodiment, a substantially constant thickness D2 is set in the second bending region γ2 of the bullet contact piece 80 over the entire area in the longitudinal direction thereof. Further, a thickness D1 larger than the thickness D2 set in the second bending region γ2 is set at the position in the longitudinal direction of the bullet contact piece 80 adjacent to the base end portion 80b (D1> D2). Then, in the bullet contact piece 80 of the present embodiment, the first bending region γ1 is formed from the thickness D2 set in the second bending region γ2 from the sliding contact portion 80x side toward the base end portion 80b side in the longitudinal direction thereof. It has a configuration as a thickness gradual change region δ in which the thickness D of the bullet contact piece 80 gradually increases up to the thickness D1 set at a position in the longitudinal direction adjacent to the base end portion 80b.

Next, the operation of the sliding load support device 81 configured as described above will be described.
Similar to the sliding load supporting device 81 of the present embodiment, the sliding load supporting device 81R of the reference example shown in FIG. 16 has base ends 80b and 80b at both ends in the longitudinal direction of the bullet contact piece 80R, and each of these groups It includes a pair of base end support portions 90, 90 that support the end portions 80b, 80b, and a support connecting portion 91 that connects the base end support portions 90, 90. Further, the bullet contact piece 80R of the sliding load support device 81R is curved in an arch shape so that the sliding contact portion 80x with respect to the sliding surface S set at the central portion in the longitudinal direction thereof is the longitudinal length of the bullet contact piece 80R. It has an arch-shaped curved shape α0 that protrudes toward the sliding surface S side (upper side in FIG. 16) of the base end portions 80b and 80b located at both ends in the direction. Then, in the sliding load support device 81R of this reference example, substantially the same thickness D0 is set over the entire longitudinal direction of the bullet contact piece 80R.

Further, FIG. 17 is a graph showing test results comparing the reference sliding load support device 81R configured as described above and the sliding load support device 81 of the present embodiment.
In FIG. 17, the waveform L1 is shown in the load application direction when the sliding load support device 81R of the above reference example is tested by pressing the flat plate-shaped load application member 101 against the bullet contact piece 80R. The relationship between the displacement amount X of the sliding contact portion 80x and the reaction force F generated by the bullet contact piece 80R, that is, the relationship between the pressing amount of the bullet contact piece 80R and the spring force is shown. Further, the waveform L2 in FIG. 17 shows the sliding contact portion 80x in the case where the sliding load supporting device 81R of the same reference example is tested by pressing the load applying member 102 in line contact with the bullet contact piece 80R. The relationship between the displacement amount X of the above and the reaction force F generated by the bullet contact piece 80R is shown. The waveform M in FIG. 17 shows the sliding contact portion 80x in the case where the sliding load supporting device 81 of the present embodiment is tested by pressing the flat plate-shaped load applying member 101 against the bullet contact piece 80. The relationship between the displacement amount X of the above and the reaction force F generated by the bullet contact piece 80 is shown.

That is, in the test of pressing the sliding load supporting device 81 of the present embodiment and the sliding load supporting device 81R of the reference example against the bullet contact pieces 80 and 80R, the flat load applying member 101 is pressed against each of these sliding. This is to reproduce the sliding contact state between the bullet contact pieces 80, 80R and the sliding surface S on the guide rail 15 side when the load supporting devices 81, 81R are used for the sunroof device 11. Then, in the test of pressing the load applying member 102 against the bullet contact piece 80R with respect to the sliding load support device 81R of the reference example, for example, a protrusion is provided on the sliding contact portion 80x of the bullet contact piece 80R, and the sliding surface S The case where the load generated by the sliding contact with the bullet contact piece 80R is input at one point in the longitudinal direction is reproduced.

More specifically, as shown in the waveform L1 in FIG. 17, when the sliding load support device 81R of the reference example is used, the displacement amount X of the sliding contact portion 80x increases due to the input of the load to the bullet contact piece 80R, that is, By increasing the amount of pressing against the sliding surface S, the reaction force F generated by the bullet contact piece 80R increases. Then, the rate of increase of the reaction force F also increases as the displacement amount X increases.

That is, in the sliding load support device 81R of the reference example, the longitudinal region in which the bullet contact piece 80R having the arch-shaped curved shape α0 as shown in FIG. 16 bends and is in sliding contact with the sliding surface S. Will increase. That is, substantially, the sliding contact portion 80x expands in the longitudinal direction, so that the longitudinal region of the bullet contact piece 80R that bends due to the input of the load to the sliding contact portion 80x is reduced. As a result, as the amount of pressing of the bullet contact piece 80R against the sliding surface S represented by the displacement amount X of the sliding contact portion 80x increases, the rate of increase of the reaction force F generated by the bullet contact piece 80R increases. Will increase.

On the other hand, as shown in the waveform L2 in FIG. 17, the load generated by the sliding contact with the sliding surface S is input at one point in the longitudinal direction of the bullet contact piece 80R, so that the sliding contact portion 80x The displacement amount X and the reaction force F generated by the bullet contact piece 80R change at a substantially constant rate.

Based on this point, in the sliding load support device 81 of the present embodiment, as described above, the bullet contact piece 80 has a corrugated curved shape αw (see FIG. 15). As a result, the bullet contact piece 80 comes into line contact with the sliding surface S, so that the sliding load support device 81 of the present embodiment also has its sliding contact portion as shown in the waveform M in FIG. The displacement amount X of 80x and the reaction force F generated by the bullet contact piece 80 change at a substantially constant rate.

Further, in the sliding load support device 81 of the present embodiment, the bullet contact piece 80 has a first bending region γ1 adjacent to the base end portion 80b in the longitudinal direction thereof and a sliding contact portion rather than the first bending region γ1. A second bending region γ2 close to 80x is provided, and a thickness D of a bullet contact piece 80 larger than the second bending region γ2 is set for the first bending region γ1.

That is, by adopting such a bending structure for the bullet contact piece 80, in the comparison between the first bending region γ1 and the second bending region γ2, the second bending region γ2 closer to the sliding contact portion 80x is better. It becomes easier to bend than the first bending region γ1. However, when paying attention to the second bending region γ2, the length of the bullet contact piece 80 as the bending region γ extending in the longitudinal direction, that is, the spring length is shortened, so that the displacement amount X of the sliding contact portion 80x is shortened. On the other hand, the reaction force F generated in the second bending region γ2 becomes large. As a result, the sliding load support device 81 of the present embodiment has the bullet contact piece 80 with respect to the sliding surface S represented by the displacement amount X of the sliding contact portion 80x, as shown in the waveform M in FIG. Even in a situation where the pressing amount is small, the bullet contact piece 80 is configured to generate a larger reaction force.

Further, in a situation where the amount of the bullet contact piece 80 pressed against the sliding surface S is large, the first bending region γ1 on the base end portion 80b side bends together with the second bending region γ2. Then, the sliding load support device 81 of the present embodiment secures the length as the bending region γ, so that the bullet contact piece 80 is generated as shown in the waveform M in FIG. The structure is such that the reaction force F does not become excessive.

Next, the effect of this embodiment will be described.
(1) The sliding load support device 81 has a bullet contact piece 80 that elastically slides against the sliding surface S in a state of extending along the sliding surface S, and a bullet contact piece 80 that elastically contacts the sliding surface S. A base end support portion 90 that supports the base end portion 80b of the bullet contact piece 80 that is separated from the sliding contact portion 80x of the piece 80 in the longitudinal direction is provided. Further, the bullet contact piece 80 has a first bending region γ1 adjacent to the base end portion 80b in the longitudinal direction of the bullet contact piece 80 and a second bending portion closer to the sliding contact portion 80x than the first bending region γ1. It includes a region γ2. Then, the direction in which the bullet contact piece 80 bends due to the input of the load to the sliding contact portion 80x is defined as the thickness direction of the bullet contact piece 80, and the first bending region γ1 is a bullet contact piece larger than the second bending region γ2. A thickness D of 80 is set.

According to the above configuration, in the comparison between the first bending region γ1 and the second bending region γ2, the second bending region γ2 close to the sliding contact portion 80x is more likely to bend than the first bending region γ1. However, when paying attention to the second bending region γ2, the length of the bullet contact piece 80 as the bending region γ extending in the longitudinal direction, that is, the spring length is shortened, so that the bullet is elastic with respect to the sliding surface S. The reaction force F generated by the second bending region γ2 becomes larger than the displacement amount X of the sliding contact portion 80x caused by the contact piece 80 being pressed, that is, the pressing amount of the bullet contact piece 80. Further, when the amount of the bullet contact piece 80 pressed against the sliding surface S is large, the first bending region γ1 on the base end portion 80b side bends together with the second bending region γ2 to form the bending region γ. The length of is secured. As a result, a large reaction force F can be obtained with a small pressing amount against the sliding surface S, and an excessive reaction force F is not generated even when the pressing amount of the bullet contact piece 80 against the sliding surface S is large. Can be done. As a result, it is possible to more effectively suppress the occurrence of rattling while suppressing the increase in sliding resistance.

In particular, in the sunroof device 11 in which the movable panel 10 is opened and closed by sliding the sliding member 20 along the guide rail 15, the magnitude of the sliding resistance affects the smooth opening and closing operation of the movable panel 10. Then, the occurrence of rattling becomes a factor that deteriorates the texture. Therefore, by using the sliding load support device 81 configured as described above, smoother operation and improvement of texture can be achieved.
(2) In the bending region γ in the longitudinal direction in which the bullet contact piece 80 bends due to the input of a load to the sliding contact portion 80x, the bullet contact piece 80 is bulleted from the sliding contact portion 80x side toward the base end portion 80b side. A thickness gradual change region δ is provided in which the thickness D of the contact piece 80 gradually increases.

According to the above configuration, stress can be prevented from being concentrated at the boundary position between the first bending region γ1 and the second bending region γ2. As a result, a stable reaction force F corresponding to the amount of the bullet contact piece 80 pressed against the sliding surface S can be generated, and at the same time, its high reliability can be ensured.

(3) In the sliding load support device 81, the thickness gradually changing region δ is provided in the first bending region γ1.
According to the above configuration, the flexibility of the second bending region γ2 can be ensured in comparison with the first bending region γ1. Further, by making the thickness D of the bullet contact piece 80 in the second bending region γ2 constant, the amount of pressing of the bullet contact piece 80 against the sliding surface S that mainly bends the second bending region γ2 is small. It is possible to accurately set the magnitude of the reaction force F generated by the bullet contact piece 80. As a result, it is possible to more effectively suppress the occurrence of rattling while suppressing the increase in sliding resistance.

(4) In the bullet contact piece 80, the sliding contact portion 80x protrudes toward the sliding surface S side from the base end portion 80b, and the bullet contact portion 80 is hit against the apex position P of the sliding contact portion 80x protruding toward the sliding surface S side. The piece 80 has a curved shape α in which the separation distance d of the bullet contact piece 80 with respect to the sliding surface S gradually increases toward the proximal end portion 80b side in the longitudinal direction of the piece 80. Then, the curved shape αw gradually increases in the amount of change in the separation distance d from the apex position P of the sliding contact portion 80x toward the longitudinal direction of the bullet contact piece 80 and the proximal end portion 80b side, and then gradually increases. It is set to the curved shape αw of the waveform that decreases to.

According to the above configuration, the bullet contact piece 80 can be brought into sliding contact with the sliding surface S at the apex position P of the sliding contact portion 80x. Further, even in a state where the sliding contact portion 80x is pressed against the sliding surface S based on the curved shape αw of the waveform, the sliding contact portion 80x is elastically deformed due to the input of the load, that is, Can have a structure in which bending is unlikely to occur. As a result, the load generated by the sliding contact with the sliding surface S can be configured to be input at one point in the longitudinal direction of the bullet contact piece 80. As a result, by securing the length of the bending region γ, it is possible to prevent an excessive reaction force F from being generated even when the amount of the bullet contact piece 80 pressed against the sliding surface S is large. ..

(5) The guide rail 15 constituting the sunroof device 11 has a sliding path 71 of a sliding member 20 having a vertical wall portion 75 and a flange portion 76 provided at the upper end portion of the vertical wall portion 75. Be prepared. Then, the sunroof device 11 is supported by the lower holding portions 84 and 86 provided on the sliding member 20, so that the sunroof device 11 is placed between the upper holding portions 83 and 85 provided on the sliding member 20. A sliding load support device 81 that slides into contact with the sliding surface S formed by the flange portion 76 while sandwiching the flange portion 76 as the wall portion is provided. As a result, it is possible to more effectively suppress the rattling of the sliding member 20 while suppressing the increase in the sliding resistance.

(6) The bullet contact piece 80 has a double-sided structure in which both ends in the longitudinal direction are the base end portions 80b and 80b, and the respective base end portions 80b and 80b are supported by a pair of base end support portions 90 and 90. As a result, the load input to the bullet contact piece 80 can be stably supported.

The above embodiment can be modified and implemented as follows. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

In the above embodiment, the sunroof device 11 including the front shoe 41 and the rear shoe 42 as the sliding member 20 and the bracket rail 23 as the support member 13 is embodied. However, the present invention is not limited to this, and the configurations of the sliding member 20 and the support member 13 for opening and closing the movable panel 10 may be arbitrarily changed.

Further, in the above embodiment, the front shoe 41 and the rear shoe 42 as the sliding member 20 are arranged in the sliding path 71. Further, the front shoe 41 and the rear shoe 42 are in sliding contact with the flange portion 76 as the wall portion constituting the sliding path 71 from above, respectively, and the upper holding portions 83, 85 and the upper holding portions 83, 85. At a position where the flange portion 76 is sandwiched between the two, the lower holding portions 84 and 86 arranged below the flange portion 76 are provided. Further, a sliding load support device 81 is provided for each of the lower holding portions 84 and 86, respectively. As a result, the lower surface 76b of the flange portion 76 is used as the sliding surface S on the guide rail 15 side, and the bullet contact piece 80 of each sliding load support device 81 supported by the sliding member 20 is slidably contacted. ..

However, the present invention is not limited to this, and the position where the sliding load support device 81 is provided and the sliding surface S to which the bullet contact piece 80 is in sliding contact may be arbitrarily changed. For example, the sliding load support device 81 supported by the sliding member 20 may be applied to a configuration in which the sliding load support device 81 is in sliding contact with any wall portion constituting the guide rail 15 from the side or above. Further, the sliding load support device 81 provided on the guide rail 15 may be applied to a configuration in which the sliding load support device 81 is in sliding contact with the sliding surface S formed by the sliding member 20. Then, such a sliding load support device 81 may be used for applications other than the sunroof device 11.

In the above embodiment, the bullet contact piece 80 has a first bending region γ1 adjacent to the base end portion 80b in the longitudinal direction thereof and a second bending region γ2 closer to the sliding contact portion 80x than the first bending region γ1. , Equipped with. Further, the thickness D of the bullet contact piece 80, which is larger than the second bending region γ2, is set in the first bending region γ1. Then, it was decided that the first bending region γ1 had a configuration as a thickness gradual change region δ. However, the present invention is not limited to this, and the position where the thickness gradual change region δ is provided does not necessarily have to be the first deflection region γ1.

For example, in the sliding load support device 81B shown in FIG. 18, a constant thickness D1 is set in the first bending region γ1 of the bullet contact piece 80B over the entire area in the longitudinal direction thereof. Further, the bullet contact piece 80B has a third bending region γ3 between the first bending region γ1 and the second bending region γ2. Then, in the sliding load support device 81B of this other example, the third bending region γ3 is a bullet from the thickness D2 set in the second bending region γ2 to the thickness D1 set in the first bending region γ1. It has a configuration as a thickness gradual change region δ in which the thickness D of the contact piece 80B gradually increases. Even if such a configuration is adopted, the same effect as that of the first embodiment can be obtained.

Further, in the longitudinal direction of the bullet contact piece 80, from the sliding contact portion 80x side toward the base end portion 80b side, the thickness D of the bullet contact piece 80 increases to three or more according to the thickness D. A separable deflection region γ may be set. In this case, the names of the bending regions arranged in the longitudinal direction of the bullet contact pieces 80 from the second to the nth are arbitrary. That is, at a position in the longitudinal direction of the bullet contact piece 80 that is closer to the sliding contact portion 80x than the first bending region γ1 adjacent to the base end portion 80b, a second bending region γ2 having a thickness D smaller than that of the first bending region γ1 is provided. All you need is. Further, also for the first deflection region γ1, it is sufficient that the portion supported by the proximal end support portion 90 where the deflection is unlikely to occur is designated as the proximal end portion 80b of the bullet contact piece 80, and the position adjacent to the proximal end portion 80b can be specified. ..

-Furthermore, for example, the second bending region γ2 may have a configuration as a thickness gradual change region δ thereof. Then, the thickness D of the bullet contact piece 80 may be changed in a step shape without having such a thickness gradual change region δ.

-In the above embodiment, the bullet contact piece 80 has a corrugated curved shape αw, but it does not necessarily have to have such a curved shape αw.
For example, in the sliding load support device 81C shown in FIG. 19, the bullet contact piece 80C has an arch-shaped curved shape α0, similar to the bullet contact piece 80R in the sliding load support device 81R of the above reference example. (See FIG. 16). Further, the bullet contact piece 80C is provided with a sliding contact portion 103 whose tip is in sliding contact with the sliding surface S at the sliding contact portion 80x. Further, the bullet contact piece 80C is closer to the sliding contact portion 80x than the first bending region γ1 adjacent to the base end portion 80b, similarly to the bullet contact piece 80 in the sliding load support device 81 of the above embodiment. The position has a second bending region γ2 having a thickness D smaller than that of the first bending region γ1. Then, also in this other example, the bullet contact piece 80C also has the first bending region γ1 in the longitudinal direction of the bullet contact piece 80C, from the sliding contact portion 80x side toward the base end portion 80b side, and the second bending region γ2. From the thickness D2 set in 1 to the thickness D1 set in the longitudinal position adjacent to the base end portion 80b, the thickness D of the bullet contact piece 80C has a configuration as a thickness gradual change region δ that gradually increases. doing.

That is, in the sliding load support device 81C of this other example, the sliding contact protrusion 103 provided on the sliding contact portion 80x is in sliding contact with the sliding surface S by line contact. As a result, the load generated by the sliding contact with the sliding surface S is input at one point in the longitudinal direction of the bullet contact piece 80. Therefore, even if such a configuration is adopted, the same effect as that of the above embodiment can be obtained.

Further, as in the above embodiment, the bullet contact piece 80 having the curved curved shape αw may be provided with such a sliding contact protrusion 103. Then, the configuration may have a second bending region γ2 having a thickness D smaller than the first bending region γ1 at a position in the longitudinal direction closer to the sliding contact portion 80x than the first bending region γ1 adjacent to the base end portion 80b. For example, similar to the bullet contact piece 80R in the sliding load support device 81R, a configuration having an arch-shaped curved shape α0 and a configuration having no sliding contact protrusion 103 may be used.

Further, in the above embodiment, the bullet contact piece 80 has a curved long substantially square bar-shaped outer shape, so that the sliding contact portion 80x is in line contact with the sliding surface S. The cross-sectional shape of the piece 80 may be arbitrarily changed. That is, it is desirable that the load generated by the sliding contact with the sliding surface S is input at one point in the longitudinal direction of the bullet contact piece 80. For example, the sliding contact portion of the bullet contact piece 80 with respect to the sliding surface S. The configuration may be such that 80x makes point contact.

Next, the technical idea that can be grasped from the above-described embodiment and modified example will be described.
