Description

[Technical field]

[0001] The present disclosure relates to a steering device. [Background technology]

[0002] Conventionally, there exists a steering device equipped with a cover that covers a portion that is gripped by a driver. In the steering device of Patent Document 1, the cover is equipped with a line fastener. The cover becomes cylindrical when the line fastener is closed. In the cover in a cylindrical state, the line fastener is provided along the longitudinal direction of the cylindrical shape. When the line fastener is closed, the cover in a cylindrical state becomes flat when the line fastener is opened. In the steering device of Patent Document 1, an annular core metal is covered with a polyurethane coating layer. When the line fastener is closed, the cover in a cylindrical state is bonded to the surface of the coating layer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-94728 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the steering device of Patent Document 1, the cover covers the surface of the coating layer by being maintained in a cylindrical shape by a reversible openable and closable linear fastener. However, since the cover is bonded to the coating layer, it is difficult to replace the cover.

[0005] On the other hand, in the steering device of Patent Document 1, if the cover is not adhered to the coating layer, when a driver holds the steering device through the cover and operates the steering device, the cover is likely to shift in the longitudinal direction of its cylindrical shape relative to the internal structure that it covers. [Means for solving the problem]

[0006] The present disclosure can be realized in the following forms.

[0007] (1) According to one aspect of the present disclosure, there is provided a steering device for a moving body, the steering device comprising: a gripping part to be gripped by a driver; and a rotating part to be rotated by the driver via the gripping part, the gripping part comprising: an operated part to be moved by the driver and rotated together with the rotating part; and a cover part to be gripped by the driver together with the operated part and moved by the driver, the cover part comprising a closed line fastener and configured to be detached from the operated part by opening the line fastener, one of the operated part and the cover part having a recess for receiving a part of the other of the operated part and the cover part, the recess being partially defined by a surface facing the part of the other of the operated part in the direction of the rotation and in contact with the part of the other of the operated part. In this embodiment, when the cover part of the grip part is gripped and moved by the driver, the force applied by the driver is transmitted between a part of the other of the operated part and the cover part, which is disposed in a recess of the other of the operated part and the cover part, and the surface defining the recess. That is, the surface defining the recess is pressed against the configuration within the recess, or the configuration within the recess is pressed against the surface defining the recess. As a result, when the grip part is gripped and moved by the driver, the cover part is less likely to slip relative to the operated part. (2) In the steering device of the above form, the operated part includes a first part extending along the direction of rotation and a second part connecting the first part and the rotating part, the steering device has an attachment member that is detachably attached to the second part and has higher rigidity than the cover part, one of the operated part and the cover part is the cover part, the other of the operated part and the cover part is the operated part, the part of the other is a part of the second part, the cover part forms the recess by bending into a shape that follows the part of the second part, the steering device includes a held part that is held by being sandwiched between the second part and the attachment member, and the surface that contacts the part of the other includes a surface of the held part that contacts the second part. With this configuration, when the driver grips and moves the gripping portion, the force applied to the cover portion by the driver is effectively transmitted to the operated portion by the held portion that is held between the second portion and the mounting member. In other words, the cover portion is less likely to slip out of place relative to the operated portion. (3) In the steering device of the above embodiment, the retained portion may have an overlapping portion in which two portions of the sheet-like member constituting the cover portion are connected to portions constituting the recess along the portion of the second portion and are not in contact with the portion of the second portion, and have an overlapping configuration. With this configuration, the two portions of the sheet-like member are overlapped, and at the overlapping portion having a thickness greater than the other portions of the cover portion, the held portion can be firmly sandwiched between the second portion of the operated portion and the attachment member, making it more difficult for the cover portion to slip off relative to the operated portion. In addition, a portion of the sheet-like member that forms a recess and is connected to two portions of the overlapping portion sandwiched between the second portion and the mounting member can form a three-dimensional recess along a portion of the second portion. (4) In the steering device of the above form, the cover portion may include a sheet-like member covering at least a portion of the operated portion, the line fastener may include an outer edge portion provided along the outer edge of the sheet-like member, the one of the operated portion and the cover portion may be the operated portion, the other of the operated portion and the cover portion may be the cover portion, the operated portion may include the recess, and the outer edge portion may be disposed within the recess as the part of the other, between the sheet-like member and the operated portion. In such an embodiment, the outer edge portion of the line fastener can be utilized to reduce the possibility of the cover portion being displaced relative to the operated portion when the grip portion is gripped and moved by the driver. (5) In the steering device of the above aspect, the operated portion may have a surface provided with projections and recesses for increasing friction between the operated portion and the cover portion. The frictional force generated between the portion provided with the projections and recesses and the cover portion makes it more difficult for the cover portion and the portion to be operated to slip. The present disclosure may be realized in various forms other than a steering device, for example, a cover for a steering device, a covered portion of a steering device, a vehicle including a steering device, a manufacturing method for a steering device, etc. [Brief description of the drawings]

[Figure 11] FIG. 11 is a perspective view of a steering device 1S according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A. First embodiment: 1 is a front view of a steering device 1 according to a first embodiment. The steering device 1 is mounted on a vehicle. The steering device 1 is operated by a driver of the vehicle to control the traveling direction of the vehicle. The steering device 1 includes a grip portion 100, a rotating portion 200, a central member 300, and mounting members 400, 400.

[0010] The rotating part 200 is rotated by the driver via the grip part 100 (see the center of FIG. 1). The traveling direction of the vehicle is determined by the orientation, i.e., the angular position, of the rotating part 200. In FIG. 1, the rotating part 200 is covered by a central member 300.

[0011] The central member 300 covers the rotating part 200 and a part of the grip part 100 from both sides in the direction of the rotation axis of the rotating part 200 (see the center part in FIG. 1). When the steering device 1 is in a state in which the steering device 1 designates the front as the traveling direction of the vehicle, the central member 300 connects the first part 111 of the grip part 100 and the rotating part 200 at the six o'clock position on a clock. The first part 111 of the grip part 100 will be described later.

[0012] The mounting members 400 are detachably attached to the two second portions 112 of the grip portion 100 (see the middle part of FIG. 1). The mounting members 400 have higher rigidity than the cover portion 120. Specifically, the mounting members 400 are switch units that allow the driver to input instructions to control the vehicle. The second portions 112 of the grip portion 100 and the cover portion 120 will be described later.

[0013] The grip portion 100 is a portion that is gripped by a driver. The grip portion 100 is located around the periphery of the rotating portion 200. The grip portion 100 includes an operated portion 110 and a cover portion 120.

[0014] 2 is a front view of the steering device 1 with the cover part 120 of the grip part 100, the central member 300, and the mounting member 400 removed. The operated part 110 is disposed symmetrically with respect to the rotating part 200. The operated part 110 is a member having a substantially circular outer shape located around the rotating part 200. The operated part 110 is moved by the driver and rotated together with the rotating part 200. The operated part 110 includes a first part 111 and a second part 112.

[0015] The first part 111 extends along the direction of rotation DR in which the operated part 110 rotates together with the rotating part 200. More specifically, the first part 111 has an annular outer shape. The annular first part 111 is disposed so as to surround the rotating part 200. The first part 111 includes an annular core made of metal and a polyurethane coating layer that covers the surface of the core. The first part 111 is also called a "wheel part."

[0016] The second portion 112 connects the first portion 111 and the rotating portion 200 (see the middle part of FIG. 2). More specifically, when the steering device 1 is in a state in which the forward direction is designated as the traveling direction of the vehicle, the second portion 112 connects the rotating portion 200 and the annular first portion 111 at the 3 o'clock and 9 o'clock positions on a clock. The second portion 112 is also called a "spoke portion."

[0017] 3 is an enlarged view of a part of the first part 111 having an annular outer diameter. The operated part 110 has a surface provided with irregularities 111sc that increase the frictional force between the operated part 110 and the cover part 120 that covers the operated part 110. The irregularities 111sc are formed by scraping the surface of the polyurethane coating layer of the first part 111 with sandpaper. Scraping the surface of the coating layer with sandpaper increases the roughness of the surface of the coating layer.

[0018] With this configuration, the frictional force generated between the portion of the surface of the first portion 111 where the unevenness 111sc is provided and the inner surface of the cover portion 120 is increased by the so-called anchor effect, making it more difficult for the cover portion 120 and the operated portion 110 to slip.

[0019] Fig. 4 is a front view showing the cover part 120 of the grip part 100 before being attached to the steering device 1. The cover part 120 covers the annular first part 111 of the operated part 110 (see Figs. 1 and 2). The cover part 120 further covers a part 112c of the second part 112 of the operated part 110. The cover part 120 is gripped by the driver together with the operated part 110 and moved by the driver (see arrow DR in Fig. 4).

[0020] The cover part 120 has a lower rigidity than the mounting member 400 as a whole (see the middle part of FIG. 1 and FIG. 4). The rigidity of the cover part 120 and the mounting member 400 is evaluated as follows. A sample is prepared by cutting the sheet-like member 121 constituting the cover part 120 into a rectangular shape. Meanwhile, a sample is prepared by cutting the material constituting the outer shell of the mounting member 400 into the same thickness as the sheet-like member 121 and cutting it into the same shape as the sample of the sheet-like member 121. One end of the longitudinal direction of each sample is held so that the largest surface of each sample includes the vertical direction and the longest side of each sample includes the horizontal direction. An external force of the same magnitude is applied to each other end in a direction perpendicular to the largest surface of the sample. Of the two samples, the one with a larger amount of deformation in the direction perpendicular to the largest surface of the sample can be determined to be a sample made of a material with lower rigidity.

[0021] The cover portion 120 includes a sheet-like member 121 and a line fastener 122 .

[0022] The sheet-like member 121 covers the first portion 111 of the operated portion 110. The sheet-like member 121 further covers a part 112c of the second portion 112 of the operated portion 110. The part 112c of the second portion 112 of the operated portion 110 covered by the sheet-like member 121 is a part of the second portion 112 that includes the upper end edge and extends in a direction from the first portion 111 toward the rotating portion 200 (see the middle part of FIG. 2). The sheet-like member 121 is flexible. The sheet-like member 121 can be made of, for example, genuine leather, synthetic leather, cloth, or the like. The configuration of the sheet-like member 121 will be described in further detail later.

[0023] The linear fastener 122 is composed of a pair of rows of elements, each of which has a protrusion and a recess near its tip, arranged in a row. In each element, the protrusion and the recess are arranged on the opposite side of the element near its tip. The protrusion protrudes in the direction in which the elements are arranged. The recess is recessed in the direction in which the elements are arranged. The space defined by the recess has the same shape as a part including the tip of the protrusion. The protrusion of each element in one row of a pair of elements arranged opposite each other is accommodated in the recess of each element in the other row, and the protrusion of each element in the other row is accommodated in the recess of each element in the one row, thereby interlocking the rows of the pair of elements. The rows of the pair of elements are disengaged by bending them in directions away from each other.

[0024] When the cover portion 120 is attached to the operated portion 110, the line fastener 122 is closed. By opening the line fastener 122, the cover portion 120 can be removed from the operated portion 110 (see Figs. 1, 2, and 4). The line fastener 122 includes an outer edge portion 122e and a protruding portion 122p.

[0025] A portion of the linear fastener 122 provided along the outer edge 121e of the sheet-like member 121 is referred to as an outer edge portion 122e (see FIG. 4). A portion of the linear fastener 122 protruding from the outer edge 121e of the sheet-like member 121 is referred to as a protruding portion 122p.

[0026] In such a configuration, since the linear fastener 122 has the protruding portion 122p in addition to the outer edge portion 122e, the outer edges 121e of the sheet-like member 121 of the cover portion 120 can be tightly closed by the linear fastener 122.

[0027] 5 is a front view of the steering device 1 in a state in which the cover portion 120 is attached and the line fastener 122 is closed, and before the protruding portion 122p is appropriately positioned. In the state of FIG. 5, the central member 300 and the mounting member 400 are not attached to the steering device 1 (see the center of FIG. 1).

[0028] When the line fastener 122 is closed, an outer edge portion 122e of the line fastener 122 is disposed along the surface of the grip portion 100 (see Figs. 1 and 5). In the state shown in Fig. 5, a protruding portion 122p of the line fastener 122 is exposed to the outside.

[0029] 6 is a perspective view showing a slider SL for closing the line fastener 122. The unclosed line fastener 122 is arranged such that corresponding structures face each other, and is closed by passing the slider SL. The slider SL is independent of the line fastener 122. After the line fastener 122 is closed, the slider SL is detached from the line fastener 122. The closed line fastener 122 can be opened by passing the slider SL.

[0030] Fig. 7 is an enlarged view showing a portion of the cover part 120 that houses the part 112c of the second part 112 of the operated part 110. The portion shown in Fig. 7 corresponds to the portion of the cover part 120 shown in the middle right part of Fig. 4 and the middle right part of Fig. 5. The part 112c of the second part 112 of the operated part 110 housed by the cover part 120 is disposed above the second part 112 of the operated part 110 and is a portion that protrudes from the annular first part 111 towards the rotating part 200 (see the middle part of Fig. 2).

[0031] Fig. 8 is a diagram showing a state in which a portion of the cover portion 120 that houses the part 112c of the second portion 112 of the operated portion 110 is viewed from an angle different from that of Fig. 7. The cover portion 120 forms a recess 120R by bending into a shape that fits the part 112c of the second portion 112. In other words, the portion 120C that forms the recess 120R is formed in a bag shape.

[0032] The recess 120R formed by the cover portion 120 receives the part 112c of the second portion 112 of the operated portion 110 (see the middle part of FIG. 2, the middle part of FIG. 4, and the middle part of FIG. 5). The recess 120R formed by the cover portion 120 is partially defined by a surface 120Rs that faces and contacts the part 112c of the second portion 112 of the operated portion 110 in the direction of rotation DR (see the upper part of FIG. 8).

[0033] With this configuration, when the cover part 120 of the grip part 100 is gripped and moved by the driver, the force applied by the driver is transmitted between the part 112c of the operated part 110 arranged in the recess 120R of the cover part 120 and the surface 120Rs. That is, the surface 120Rs is pressed against the configuration 112c in the recess 120R along the direction DR, or the configuration 112c in the recess 120R is pressed against the surface 120Rs along the direction DR (see Figs. 1, 5 and 7). As a result, when the grip part 100 is gripped and moved by the driver, the cover part 120 is less likely to slip relative to the operated part 110, compared to a mode in which the entire cover part only covers the operated part 110 along the rotation direction DR.

[0034] The sheet-like member 121 of the cover part 120 has a held part 121h (see the middle part of FIG. 7, the top part of FIG. 8, and the middle part of FIG. 5). The held part 121h is a part that is sandwiched and held between the second part 112 of the operated part 110 and the attachment member 400 (see the middle part of FIG. 1). Of the held part 121h, the part having the widest width in the direction of the rotation axis of the rotating part 200 has a width of 5 mm or more.

[0035] With this configuration, when the grip part 100 is gripped and moved by the driver, the force applied to the cover part 120 by the driver is effectively transmitted to the operated part 110 by the held part 121h that is sandwiched and held between the second part 112 and the mounting member 400. That is, the cover part 120 is less likely to slip relative to the operated part 110 compared to an embodiment that does not include the held part 121h.

[0036] The held portion 121h of the sheet-like member 121 has an overlapping portion 121f (see the middle part of FIG. 7 and the upper part of FIG. 8). More specifically, one held portion 121h has three overlapping portions 121f. The overlapping portions 121f have a configuration in which two parts of the sheet-like member 121 are overlapped and bonded to each other. The two overlapping portions are parts of the sheet-like member 121 constituting the cover portion 120 that are connected to the part 120C constituting the recess 120R along the part 112c of the operated portion 110, respectively, and are not in contact with the part 112c of the operated portion 110. When the attachment member 400 is attached to the second part 112 of the gripping portion 100, the overlapping portion 121f is sandwiched between the second part 112 and the attachment member 400 as a part of the held portion 121h (see the middle part of FIG. 1).

[0037] With this configuration, portion 120C connected to the two mutually adhered portions of overlapping portion 121f can form a three-dimensional recess 120R along part 112c of second portion 112 without wrinkles (see Figures 7 and 8).

[0038] Furthermore, in overlapping portion 121f, which has a configuration in which two portions of sheet-like member 121 are overlapped and has a thickness greater than other portions of cover portion 120, held portion 121h can be firmly sandwiched between second portion 112 of operated portion 110 and attachment member 400 (see the middle part of FIG. 1). Therefore, cover portion 120 is less likely to slip relative to operated portion 110 compared to an embodiment that does not have overlapping portion 121f.

[0039] 9 is a cross-sectional view of the operated part 110 taken along line IX-IX in FIG. 2. More specifically, FIG. 9 is a view showing the structure of the operated part 110 in a cross section perpendicular to the rotation direction DR. In order to facilitate understanding of the technology, the core metal and coating layer of the first part 111 are omitted in FIG. 9. The first part 111 of the operated part 110 has a recess 110R on its surface (see FIG. 2). The recess 110R is provided on the surface of the annular first part 111 that faces the rotating part 200.

[0040] The four protruding parts 122p of the linear fastener 122 shown above and below the second part 112 of the grip part 100 in Fig. 5 are arranged on the central rotating part 200 after the state of Fig. 5, and the central member 300 is attached so as to cover the protruding parts 122p. As a result, the four protruding parts 122p cannot be seen from the outside. On the other hand, the outer edge part 122e of the linear fastener 122 connected to the protruding parts 122p is arranged in the recess 110R between the sheet-like member 121 constituting the cover part 120 and the first part 111 of the operated part 110 (see the upper center part of Fig. 9).

[0041] The recess 110R of the operated part 110 receives the outer edge portion 122e of the linear fastener 122. The recess 110R of the operated part 110, which is located near the connection part with the second part 112, is partially defined by a surface 110Rs that faces the outer edge portion 122e of the linear fastener 122 in the direction of rotation DR and contacts the outer edge portion 122e of the linear fastener 122 in the direction of rotation DR (see the middle left and middle right parts of FIG. 2). More specifically, the surface 110Rs that defines the recess 110R of the operated part 110 is a surface that defines the vicinity of the end of the recess 110R located in the lower half of the annular operated part 110 in the direction of rotation DR, which is close to the 3 o'clock or 9 o'clock position.

[0042] In such a configuration, the outer edge portion 122e covered by the sheet-like member 121 is utilized as a convex portion and accommodated within the recess 110R, thereby further reducing the possibility that the cover portion 120 will shift relative to the operated portion 110 when the grip portion 100 is gripped and moved by the driver.

[0043] Fig. 10 is a diagram showing the cover part 120 in a state where the linear fastener 122 is closed by the slider SL. Fig. 10 shows the operated part 110 in Fig. 9 as viewed from above to below in Fig. 9. Note that, in order to facilitate understanding of the technology, the sewing thread that fastens the outer edge portion 122e of the linear fastener 122 to the outer edge 121e of the sheet-like member 121 is not shown in Fig. 9.

[0044] As described above, the outer edge portion 122e of the linear fastener 122 is disposed in the recess 110R between the sheet-like member 121 constituting the cover portion 120 and the first portion 111 of the operated portion 110 (see the upper center portion of FIG. 9). As a result, the opposing outer edges 121e, 121e of the sheet-like member 121 of the cover portion 120 can be joined by the outer edge portion 122e of the linear fastener 122 without leaving any gap between them.

[0045] The operated portion 110 also has a recess 112R in the second portion 112, which has a similar function to the recess 110R (see the middle left and middle right parts of FIG. 2). The recess 112R is provided on the surface of the second portion 112, near the upper edge of a part 112c of the second portion 112. An outer edge portion 122e of the line fastener 122 shown in the lower part of FIG. 8 is disposed in the recess 112R between the sheet-like member 121 constituting the cover portion 120 and the second portion 112 of the operated portion 110.

[0046] In this embodiment, the cover portion 120 is fixed onto the operated portion 110 by a line fastener 122. The combination of the physical shapes of each portion, such as the part 112c of the operated portion 110 and the surface 120Rs, the recess 110R and the outer edge portion 122e, and the recess 112R and the outer edge portion 122e, reduces the possibility that the cover portion 120 will be displaced from the operated portion 110 without using adhesive (see FIGS. 1 to 3, 5, 7, and 9). Therefore, in the steering device 1 of this embodiment, it is easy to replace the cover portion 120.

[0047] The vehicle in this embodiment is also called a "mobile body."

[0048] B. Second embodiment: FIG. 11 is a perspective view of a steering device 1S as a second embodiment. The function of the steering device 1S of the second embodiment is the same as that of the steering device 1 of the first embodiment. In FIG. 11, among the configurations of the steering device 1S of the second embodiment, components corresponding to those of the steering device 1 of the first embodiment are given reference numerals with "S" added to the end of the reference numerals given to the respective components of the steering device 1 (see FIG. 1, FIG. 2, and FIG. 11). Below, among the configurations of the steering device 1S, those points that are different from the configuration of the steering device 1 will be described. Other points of the steering device 1S are the same as those of the steering device 1.

[0049] In the steering device 1 of the first embodiment, the first portion 111 of the operated portion 110 has an annular outer shape (see FIG. 2). In contrast, in the steering device 1S of the second embodiment, the first portions 111S of the operated portion 110S are symmetrical with respect to the rotating portion 200S, and each extends along the direction of rotation DR, but are configured as a pair separated from each other (see the left and right parts in FIG. 11).

[0050] The second portion 112S of the operated portion 110S connects the first portion 111S and the rotating portion 200S. More specifically, the second portion 112S connects the first portion 111S and the rotating portion 200S at the upper end of the first portion 111S extending along the direction of rotation DR (see the upper left and upper right parts of FIG. 11).

[0051] The second portion 112S of the operated portion 110S further connects the first portion 111S and the central member 300S. More specifically, the second portion 112S connects the first portion 111S and the central member 300S at the lower end of the first portion 111S extending along the direction of rotation DR (see the lower left and lower right parts of FIG. 11).

[0052] In the second embodiment, the cover portion 120S also has a recess 120RS that receives a part 112cS of the operated portion 110S (see the upper left and upper right parts of FIG. 11). Since the recess 120RS is located on the back surface side of the cover portion 120S, the recess 120RS is shown by a dashed line with a leading line in the upper left and upper right parts of FIG.

[0053] The recess 120RS is formed by bending the sheet-like member 121S into a shape that follows the part 112cS of the second portion 112S. The recess 120RS is partially defined by a surface 120RsS that faces the part 112cS of the operated part 110S in the direction of rotation DR and is in contact with the part 112cS of the operated part 110S.

[0054] With this configuration, when the cover portion 120S of the grip portion 100S is gripped and moved by the driver, the force applied by the driver is transmitted between the part 112cS of the operated portion 110S arranged in the recess 120RS of the cover portion 120S and the surface 120RsS defining the recess 120RS. As a result, when the grip portion 100S is gripped and moved by the driver, the cover portion 120S is less likely to slip relative to the operated portion 110S.

[0055] The second portion 112S of the operated portion 110S has a recess 110RS on the side facing the rotating portion 200S (see the left and right parts in FIG. 11). The outer edge portion 122eS of the line fastener 122S is disposed in the recess 110RS between the sheet-like member 121S constituting the cover portion 120S and the second portion 112S of the operated portion 110S (see the left and right parts in FIG. 11).

[0056] The recess 110RS of the operated portion 110S is partially defined by a surface 110RsS that faces the outer edge portion 122eS of the linear fastener 122S in the direction of rotation DR and is in contact with the outer edge portion 122eS of the linear fastener 122S. More specifically, the surface 110RsS that defines the recess 110RS of the operated portion 110S is a surface that defines the bottom of the recess 110RS in the recess 110RS near the central member 300S (see the lower left and lower right parts of FIG. 11).

[0057] In such a configuration, the outer edge portion 122eS covered by the sheet-like member 121S of the cover portion 120S is utilized as a convex portion and accommodated within the recess 110RS, thereby reducing the possibility that the cover portion 120S will shift relative to the operated portion 110S when the grip portion 100S is gripped and moved by the driver.

[0058] C. Other embodiments: C1. Alternative embodiment 1: (1) In the first embodiment, the cover portion 120 covers the annular first portion 111 of the operated portion 110 and a part 112c of the second portion 112 of the operated portion 110 (see FIGS. 1 and 2). However, the cover portion may be configured to cover the entire operated portion. More specifically, the sheet-like member of the cover portion may be configured to cover the entire operated portion.

[0059] (2) In the above first embodiment, the inner surface 120Rs of the recess 120R formed by the cover portion 120 faces and contacts the part 112c of the second portion 112 of the operated portion 110 (see the upper part of FIG. 8 and the middle part of FIG. 2). The inner surface 120Rs of the recess 120R formed by the cover portion 120 may further include a surface that contacts other parts of the second portion 112 of the operated portion 110 and the first portion 111.

[0060] (3) In the first embodiment, the surface 120Rs that faces and contacts the part 112c of the second part 112 of the operated part 110 in the direction of rotation DR is the back surface of the held part 121h of the sheet-like member 121 (see the upper part of FIG. 8). The cover part 120 of the grip part 100 may have a surface that faces the back surface 120Rs of the held part 121h of the sheet-like member 121 with the part 112c of the second part 112 sandwiched therebetween. This surface can also face and contact the part 112c of the second part 112 of the operated part 110 in the direction of rotation DR. Note that the surface that faces and contacts the part of the other component in the direction of rotation of the operated part is preferably arranged at an angle of 45° or more with respect to the direction of rotation of the operated part and faces each other, and is preferably arranged at an angle of 60° or more with respect to the direction of rotation of the operated part, and is more preferably arranged at an angle of 80° or more with respect to the direction of rotation of the operated part.

[0061] (4) In the first embodiment, the operated portion 110 has a surface provided with unevenness 111sc that increases the frictional force between the operated portion 110 and the cover portion 120 (see FIG. 3). The unevenness 111sc is formed by scraping the surface of the polyurethane coating layer of the first portion 111 with sandpaper. However, the unevenness of the operated portion may be unevenness that is provided in advance on the coating layer when the coating layer is manufactured using a mold. As the unevenness that is formed in advance on the coating layer using a mold, a "grain" provided on the surface of the coating layer can be used. Such unevenness may be provided on the entire surface of the operated portion 110, or may be provided on only a part of the surface of the operated portion 110.

[0062] Such unevenness can also be provided on the surface of the cover that comes into contact with the operated part. The unevenness provided on the surface of the cover that comes into contact with the operated part can also be provided by forming the back surface of the cover with a woven or nonwoven fabric. The unevenness provided on the surface of the cover that comes into contact with the operated part can also be made larger by subjecting the back surface of the cover to a nap-raising process. It is more preferable that the unevenness that increases the frictional force with the cover be provided on the front surface of the operated part.

[0063] (5) In the first embodiment, the mounting member 400 is a switch unit through which the driver inputs instructions to control the vehicle (see the middle part of FIG. 1). However, the mounting member may be another part, such as a decorative part attached to the steering device to improve the aesthetics.

[0064] (6) In the first embodiment, the cover 120 includes a line fastener 122 (see FIG. 5). However, the cover may include a hook-and-loop fastener arranged along the outer edge of the sheet-like member instead of the line fastener. The hook-and-loop fastener is configured by a pair of a member including a number of elastic ring-shaped structures arranged two-dimensionally, and a member including a number of elastic hook-shaped structures arranged two-dimensionally. At least a part of the number of hook-shaped structures engages with at least a part of the number of ring-shaped structures, thereby engaging the pair of members. The pair of members is disengaged by being bent or rotated in a direction away from each other.

[0065] (7) In the first embodiment, the cover portion 120 is not adhered to the operated portion 110. However, the cover portion 120 may be adhered or stuck to the operated portion 110 with a strength that allows the cover portion 120 to be peeled off without being destroyed.

[0066] (8) In the first embodiment, the steering device 1 is mounted on a vehicle (see FIG. 1). However, the steering device of the present disclosure may also be mounted on other moving objects whose traveling direction is controlled by a driver, such as a ship or an aircraft.

[0067] C2. Alternative embodiment 2: In the first embodiment, the sheet-like member 121 of the cover portion 120 includes a held portion 121h (see the middle of FIG. 7, the top of FIG. 8, and the middle of FIG. 5). The held portion 121h is a portion that is sandwiched and held between the second portion 112 of the operated portion 110 and the mounting member 400 (see the middle of FIG. 1). However, the sheet-like member 121 of the cover portion 120 may be configured not to include the held portion 121h. Even in such an embodiment, a steering device in which the cover portion is less likely to slip relative to the operated portion can be configured by having one of the operated portion and the cover portion have a recess that receives a part of the other and is partially defined by a surface that faces and contacts the part of the other in the rotation direction DR.

[0068] C3. Alternative embodiment 3: In the first embodiment, the held portion 121h of the sheet-like member 121 has an overlapping portion 121f (see the middle part of FIG. 7 and the top part of FIG. 8). The overlapping portion 121f has a configuration in which two portions of the sheet-like member 121 are overlapped and adhered to each other. However, the overlapping portion may be formed by sewing or embossing.

[0069] Furthermore, the sheet-like member 121 may have no overlapping portion. For example, by forming the sheet-like member from a material that maintains a certain degree of flexibility and a three-dimensional shape by heat pressing, it is possible to form a sheet-like member that covers at least a part of the operated portion and the held portion without having an overlapping portion.

[0070] In addition, when the sheet-like member is formed into a three-dimensional shape, a cutout portion can be formed by removing a portion of the sheet-like member that overlaps with another portion of the sheet-like member in advance. In such an embodiment, the recess 120R can be formed three-dimensionally without wrinkles.

[0071] C4. Alternative embodiment 4: In the first embodiment, the outer edge portion 122e of the line fastener 122 is disposed in the recess 110R between the sheet-like member 121 constituting the cover portion 120 and the first portion 111 of the operated portion 110 (see the upper center portions of FIGS. 8 and 9). However, the operated portion of the steering device may not have such a recess, and as shown in the upper portion of FIG. 8, the cover portion 120 covering the operated portion may form the recess 120R.

[0072] C5. Alternative Embodiment 5: In the first embodiment, the operated part 110 has a surface provided with unevenness 111sc that increases the frictional force between the operated part 110 and the cover part 120. The unevenness 111sc is formed by scraping the surface of the polyurethane coating layer of the first part 111 with sandpaper (see FIG. 3). However, the operated part may have an aspect that does not have such unevenness. Even in such an aspect, a steering device in which the cover part is less likely to slip out of place relative to the operated part can be configured by having one of the operated part and the cover part have a recess that receives a part of the other and is partially defined by a surface that faces and contacts the part of the other in the rotation direction DR.

[0073] The present disclosure is not limited to the above-mentioned embodiment, and can be realized in various configurations without departing from the spirit of the present disclosure. For example, the technical features of the embodiments corresponding to the technical features in each aspect described in the Summary of the Invention can be appropriately replaced or combined to solve some or all of the above-mentioned problems or to achieve some or all of the above-mentioned effects. Furthermore, if a technical feature is not described as essential in this specification, it can be appropriately deleted. [Explanation of symbols]
