Description

[Technical Field]

[0001] The present invention relates to a starter motor cover attached to a starter motor for protecting a harness extending from the starter motor. [Background Art]

[0002] When starting a vehicle engine by a cell starter, electric power is supplied from a starter relay to a starter motor. Generally, a starter motor cover for protecting the terminal portion of a starter motor and a power line connected to the terminal portion is attached thereto.

[0003] As a starter motor cover, as disclosed in Patent Document 1, a starter terminal protection cover including a case portion for protecting the terminal portion of the starter motor and a cylindrical portion for protecting the power line has been proposed.

[0004] Recently, in addition to the harness protection cover portion corresponding to the case portion and the cylindrical portion of Patent Document 1, there is provided a motor mounting portion to be attached to the outer cylinder of the motor, and by attaching the motor mounting portion to the outer cylinder of the motor, there is a demand for protecting not only the terminal portion of the starter motor but also a region including the outer cylinder portion in a wide range by the harness protection cover portion.

[0005] However, in the starter motor cover, when the motor mounting portion and the harness protection cover portion having different functions are formed as a single member, the overall shape becomes complicated. For this reason, when it is attempted to integrally mold the motor mounting portion and the harness protection cover portion from resin, it has been difficult to obtain good moldability, for example, burrs are generated on the end surface of the contact surface of the motor mounting portion that contacts the outer cylinder.

[0006] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2007-252104 [Brief Summary of the Invention] [Problems that the invention aims to solve]

[0007] Therefore, the objective of this invention is to provide a starter motor cover that can achieve good moldability even when it is configured to include a motor mounting section and a harness protection cover section having different functions. [Means for solving the problem]

[0008] This invention comprises a motor mounting portion to be attached to a motor and a protective cover portion to protect a harness extending from the motor, wherein the motor mounting portion located on one side in the motor axial direction and the protective cover portion located on the other side are formed separately by resin molding so that their opposing ends can be assembled together. The protective cover comprises a first wall portion and a second wall portion, the first wall portion and the second wall portion intersect each other via a corner portion extending along the motor axis direction and adjacent ends connected to each other, the motor mounting portion is assembled to the protective cover portion straddling the first wall portion and the second wall portion and comprises a lock portion for fixing the assembled motor mounting portion and the protective cover portion, the lock portion comprises a first lock portion for fixing the first wall portion and the motor mounting portion and a second lock portion for fixing the second wall portion and the motor mounting portion, the motor mounting portion is a starter motor cover comprising at least one of a first protruding piece projecting toward the other side so as to be able to abut the inner surface of the first wall portion in the thickness direction and a second protruding piece projecting toward the other side so as to be able to abut the inner surface of the second wall portion in the thickness direction. It is characterized by the following:

[0009] This invention makes it possible to achieve good moldability by forming each of the motor mounting portion and harness protection cover portion, which have different functions, separately using resin molding.

[0010] Also, The protective cover portion comprises a first wall portion and a second wall portion, the first wall portion and the second wall portion intersect each other via a corner portion extending along the motor axis direction and adjacent ends are connected to each other, the motor mounting portion is assembled to the protective cover portion straddling the first wall portion and the second wall portion and comprises a lock portion for fixing the assembled motor mounting portion and the protective cover portion, the lock portion comprises a first lock portion for fixing the first wall portion and the motor mounting portion and a second lock portion for fixing the second wall portion and the motor mounting portion. doing .

[0011] As a result, The separately formed motor mounting portion and the protective cover portion are assembled and integrated to prevent unintended deformation due to external forces.

[0012] More specifically, in a configuration where a motor mounting section and a harness protection cover section, which are molded separately, are assembled and integrated as an aftermarket part, vibrations during vehicle operation may cause relative displacement between the harness protection cover section, which is fixed to the harness, and the motor mounting section, which is fixed to the motor, potentially resulting in bending stress acting on the assembly portion of both components. However, this invention can prevent deformation such as the motor mounting section tilting inward or outward relative to the harness protection cover section, even under such bending stress.

[0013] More specifically, the motor mounting portion and the protective cover portion are fixed to the first lock portion and the second lock portion such that the motor mounting portion is assembled to straddle the first wall portion and the second wall portion of the protective cover portion.

[0014] In this way, since the first locking portion and the second locking portion are not arranged on the same plane, even if an unintended external force acts on the protective cover portion and the motor mounting portion, the motor mounting portion and the protective cover portion can be assembled while suppressing relative deformation between them.

[0015] For example, by suppressing inward deformation of the motor mounting portion relative to the protective cover portion, it is possible to prevent the motor mounting portion and the protective cover portion from unintentionally interfering with the harness.

[0016] Furthermore, in the starter motor cover of the present invention, external forces acting from harness fixing parts such as harness cable ties that secure the harness in the protective cover part due to vibrations during vehicle operation may cause the motor mounting part and the protective cover part to undergo relative bending deformation at the assembly part of each other, with the first lock part as the pivot point, toward the side of the second lock part or toward the opposite side of the second lock part, and also with the second lock part as the pivot point, toward the side of the first lock part or toward the opposite side of the first lock part.

[0017] However, in this specification, for convenience, when such bending deformation occurs, the motor mounting portion is described as deforming inward, i.e., tilting toward the internal space housing the harness relative to the protective cover portion, or deforming outward, i.e., tilting toward the opposite side of the internal space.

[0018] Specifically, when the motor mounting portion and the protective cover portion are described as bending relative to each other toward the second lock portion with the first lock portion as the pivot point, it is explained as the motor mounting portion bending outward relative to the second wall portion with the first lock portion as the pivot point. Similarly, when the motor mounting portion and the protective cover portion are described as bending relative to each other toward the opposite side of the second lock portion with the first lock portion as the pivot point, it is explained as the motor mounting portion bending inward relative to the second wall portion with the first lock portion as the pivot point.

[0019] Furthermore, when the motor mounting portion and the protective cover portion are described as bending relative to each other toward the first lock portion with the second lock portion as a pivot point, it is explained as the motor mounting portion bending outward relative to the first wall portion with the second lock portion as a pivot point. Similarly, when the motor mounting portion and the protective cover portion are described as bending relative to each other toward the opposite side of the first lock portion with the second lock portion as a pivot point, it is explained as the motor mounting portion bending inward relative to the first wall portion with the second lock portion as a pivot point.

[0020] Furthermore, The motor mounting portion comprises at least one of a first protruding piece that protrudes toward the other side so as to be able to abut against the inner surface of the first wall portion in the thickness direction, and a second protruding piece that protrudes toward the other side so as to be able to abut against the inner surface of the second wall portion in the thickness direction. It is.

[0021] As a result, Even if an external force acts on the motor mounting portion in a direction that causes it to tilt inward relative to the first wall surface, the inward tilting deformation of the motor mounting portion relative to the protective cover portion can be prevented.

[0022] In detail, by providing the first protruding piece on the motor mounting portion, even if an external force acts in a direction that causes the motor mounting portion to deform inwardly relative to the first wall surface portion, the first protruding piece abuts against the inner surface of the first wall surface portion and resists the external force, thereby preventing inward deformation of the motor mounting portion relative to the first wall surface portion.

[0023] Furthermore, by providing the second protruding piece on the motor mounting portion, even if an external force acts in a direction that causes the motor mounting portion to deform inwardly relative to the second wall surface portion, the second protruding piece abuts against the inner surface of the second wall surface portion and resists the external force, thereby preventing inward deformation of the motor mounting portion relative to the second wall surface portion.

[0024] child As an aspect of the invention, there are provided: a first projecting portion that intersects the motor axial direction and projects from the opposite side of the corner portion relative to the first lock portion to the opposite side in a first extending direction along the first wall surface portion; and a second projecting portion that intersects the motor axial direction and projects from the opposite side of the corner portion relative to the second lock portion to the opposite side in a second extending direction along the second wall surface portion, wherein the first projecting portion may be formed to have a longer projection length than the second projecting portion, and the second protruding piece may be formed to have a longer projection length toward the other side than the first protruding piece.

[0025] According to this invention, even if an external force acts on the first projecting portion which has a longer projection length than the second projecting portion, inward deformation of the motor mounting portion relative to the second wall surface portion can be more reliably prevented by the second protruding piece which has a longer projection length toward the other side than the first protruding piece.

[0026] Also as an aspect of the invention, in the protruding portion of the second protruding piece that protrudes toward the other side beyond the first protruding piece, a flange portion protruding in the first extending direction may be provided from at least a part of the motor axial direction of the end portion on the corner portion side in the second extending direction.

[0027] With this invention, a ridge extending in the motor axial direction is formed at the base end of the flange portion, thereby increasing the strength of the second protruding piece.

[0028] In another aspect of this invention, the inner surface of the first wall portion may be provided with transverse ribs extending in the first extending direction, and the transverse ribs may be provided so as to be able to abut against the tip of the first protruding piece in the protruding direction.

[0029] With this invention, the first wall portion can be reinforced by the transverse ribs, so that even if an unintended external force acts on the protective cover portion equipped with the first wall portion, the harness can be securely protected by the protective cover portion.

[0030] Furthermore, even if an external force acts on the motor mounting portion in a direction that causes it to tilt inward relative to the second wall portion, the tip of the first protruding piece in the direction of protrusion contacts the transverse rib that reinforces the first wall portion, thereby resisting the external force and preventing the motor mounting portion from tilting inward relative to the second wall portion.

[0031] In another aspect of this invention, the inner surface of the first wall portion is provided with longitudinal ribs extending from one position on the motor axis side to the other position relative to the tip of the second protruding piece in the protruding direction, and these longitudinal ribs may be connected to the transverse ribs.

[0032] This invention allows the first wall surface to be reinforced over a wide area in the motor axial direction by the longitudinal ribs. Therefore, the harness can be securely protected against unwanted external forces.

[0033] Furthermore, since the transverse ribs can be supported by the longitudinal ribs connected to the transverse ribs, the transverse ribs can resist the external force acting when the tip of the first protruding piece in the protruding direction comes into contact with them. Therefore, it is possible to prevent the motor mounting portion from tilting inward relative to the second wall portion.

[0034] In another aspect of this invention, the motor mounting portion is provided with a first assembly portion that is assembled to the first wall surface, and the first assembly portion has a support portion that supports the first protruding portion that extends from the first assembly portion, and the support portion may be arranged across the thickness direction of the first wall surface and on the opposite side of the corner portion from the first lock portion in the first extending direction.

[0035] With this invention, even if an external force acts on the motor mounting portion in a direction that causes it to tilt inward relative to the second wall portion, the support portion, which is arranged across the thickness direction of the first wall portion and is positioned on the opposite side of the corner portion relative to the first lock portion, can resist the external force by contacting one end face of the first wall portion, thereby preventing the motor mounting portion from tilting inward relative to the second wall portion.

[0036] In another aspect of this invention, a fitting projection may be provided that protrudes from one end of the first wall portion toward the other end, and the support portion may be provided with a fitted portion that fits with the fitting projection.

[0037] With this invention, in the assembled state, the protective cover portion and the motor mounting portion can be more securely fixed because, in addition to the fixing of the first lock portion and the second lock portion, the fitting projection portion and the fitted portion are also fitted together.

[0038] Furthermore, even if an external force acts on the motor mounting portion in a direction that causes it to tilt inward relative to the first wall portion, the fitting projection engages with the fitted portion, thereby more reliably preventing the motor mounting portion from tilting inward relative to the first wall portion.

[0039] In another aspect of this invention, the first assembly portion may have a corner-side assembly portion on the corner side relative to the first lock portion, the corner-side assembly portion may be arranged across the plate thickness direction of the first wall surface portion, and the corner-side assembly portion may be provided with the fitting portion.

[0040] This invention allows the fitting projection to be fitted to the fitted portion on both the side of the support portion and the side of the corner assembly portion relative to the first lock portion. As a result, the fitting projection and the fitted portion provided on both sides of the first lock portion can resist external forces that cause the motor mounting portion to deform inward relative to the first wall portion.

[0041] In another aspect of this invention, the motor mounting portion may be provided with the first assembly portion and the second assembly portion which is assembled to the second wall portion, and a corner reinforcing portion connecting the first assembly portion and the second assembly portion may be provided on the inner corner side between the first assembly portion and the second assembly portion.

[0042] This invention connects the first assembly portion, which is attached to the first wall surface, and the second assembly portion, which is attached to the second wall surface, with the corner reinforcement portion, thereby preventing unintended deformation such as changes in the angle between the first assembly portion and the second assembly portion in response to unintended external forces.

[0043] In another aspect of this invention, the corner reinforcement portion may be connected from the inner corner side between the first assembly portion and the second assembly portion to a portion of the first assembly portion in the first extending direction corresponding to the first lock portion.

[0044] With this invention, even if an unintended external force acts on the motor mounting portion and the protective cover portion which are assembled together, and a load is applied to the first lock portion which fixes the motor mounting portion and the protective cover portion, the first lock portion can be reinforced by the corner reinforcement portion.

[0045] Furthermore, this invention comprises a motor mounting portion attached to a motor and a protective cover portion protecting a harness extending from the motor, wherein the motor mounting portion located on one side in the motor axial direction and the protective cover portion located on the other side are formed separately by resin molding so that their opposing ends can be assembled together, the protective cover portion comprises a first wall portion and a second wall portion, the first wall portion and the second wall portion intersect each other via a corner portion extending along the motor axial direction and adjacent ends are connected to each other, the motor mounting portion is assembled to the protective cover portion straddling the first wall portion and the second wall portion and comprises a lock portion for fixing the assembled motor mounting portion and the protective cover portion, the lock portion comprises a first lock portion for fixing the first wall portion and the motor mounting portion and a second lock portion for fixing the second wall portion and the motor mounting portion.The motor mounting portion is provided with a first assembly portion that is assembled to the first wall surface, and in a first extending direction that intersects with the motor axis direction and runs along the first wall surface, the first lock portion is provided at a portion of the first assembly portion spaced apart from the corner portion, and a corner-side assembly portion located on the corner side of the first lock portion in the first extending direction of the first assembly portion is arranged to span across the thickness direction of the first wall surface. It is characterized by being a starter motor cover. .

[0047] Furthermore, this invention comprises a motor mounting portion attached to a motor and a protective cover portion protecting a harness extending from the motor, wherein the motor mounting portion located on one side in the motor axial direction and the protective cover portion located on the other side are formed separately by resin molding so that their opposing ends can be assembled together, the protective cover portion comprises a first wall portion and a second wall portion, the first wall portion and the second wall portion intersect each other via a corner portion extending along the motor axial direction and adjacent ends are connected to each other, the motor mounting portion is assembled to the protective cover portion straddling the first wall portion and the second wall portion and comprises a lock portion for fixing the assembled motor mounting portion and the protective cover portion, the lock portion comprises a first lock portion for fixing the first wall portion and the motor mounting portion and a second lock portion for fixing the second wall portion and the motor mounting portion.

[Modes for carrying out the invention]

[0051] One embodiment of this invention will be described below with reference to the drawings. In the figure, arrow Z represents the motor axis direction, arrow X represents the first extension direction perpendicular to the motor axis direction and extending along the first wall surface 11 described later, and arrow Y represents the second extension direction perpendicular to the motor axis direction and extending along the second wall surface 12 described later. Furthermore, in the figure, arrow Za represents one side in the motor axis direction, arrow Zb represents the other side in the motor axis direction, arrow Xa represents one side in the first extension direction, arrow Xb represents the other side in the first extension direction, arrow Ya represents one side in the second extension direction, and arrow Yb represents the other side in the second extension direction.

[0052] As shown in Figure 1, the starter motor cover 1 of this embodiment (hereinafter abbreviated as "motor cover 1") includes a motor mounting portion 2 that is attached to the starter motor 8 (hereinafter abbreviated as "motor 8") mounted on the vehicle, and a protective cover portion 3 that protects the harness 7 extending from the motor 8.

[0053] As shown in Figures 1 to 3, the motor mounting portion 2 is positioned on the Za direction side, and the protective cover portion 3 is positioned on the Zb direction side. The motor mounting portion 2 and the protective cover portion 3 are formed separately by resin molding so that their opposing ends in the Z direction can be assembled together. As shown in Figure 2, the motor cover 1 is equipped with a first locking part 6a and a second locking part 6b as locking parts 6 that secure the motor mounting part 2 and the protective cover part 3 which are assembled together.

[0054] The protective cover section 3 includes multiple wall sections 10 that cover the harness 7 extending from the motor 8 from both sides in the X direction, and from the Ya and Zb directions. More specifically, the protective cover portion 3 comprises a first wall portion 11 that covers the harness 7 from the Ya direction side, and a second wall portion 12 that covers the harness 7 from the Xa direction side. The first wall portion 11 is formed in a substantially flat shape extending in the Z and X directions, and the second wall portion 12 is formed in a substantially flat shape extending in the Z and Y directions. The first wall portion 11 and the second wall portion 12 are perpendicular to each other via corner portions 13 that extend along the Z direction, and their adjacent ends are connected to each other.

[0055] The protective cover portion 3 is provided with a rib 14, a harness outlet portion 15, a first lock portion 6a, a fitting projection 16a on one side, a fitting projection 16b on the other side, and a second lock projection 60b.

[0056] The ribs 14 are appropriately provided on the surface in the Ya direction, i.e., the outer surface 11a, and the surface in the Yb direction, i.e., the inner surface 11b, of the first wall portion 11, and on the surface in the Xa direction, i.e., the outer surface 12a, and the surface in the Xb direction, i.e., the inner surface 12b, of the second wall portion 12. For example, as shown in Figure 3, the ribs 14 include transverse ribs 14x extending in a direction coinciding with the X direction and longitudinal ribs 14y extending in a direction coinciding with the Z direction on the inner surface 11b of the first wall portion 11.

[0057] Furthermore, as shown in Figures 2, 3, and 9(a), multiple harness outlet sections 15 are provided to allow the harness 7 to be led out from an internal space 3s covered by multiple wall sections 10 capable of accommodating the harness 7 to the outside.

[0058] For example, as shown in Figure 3, the harness outlet portion 15 includes a harness outlet portion 15a on the other side that opens toward the Zb direction at the corner portion of the protective cover portion 3 in the Xb and Zb directions. A harness fixing portion 17 is formed to be flexible and elongated so that it can be wrapped around the harness 7 and fixed with tape or the like, and extends toward the Zb direction from both the Xb and Zb ends of the harness outlet portion 15a on the other side.

[0059] As shown in Figures 2, 4, 6(a), 7(a), 8(a), and 9(b), the first locking projection 60a is provided on the first locking portion 6a and is positioned at the end of the first wall portion 11 in the Za direction, spaced apart from the corner portion 13 in the Xb direction, and projecting in the Za direction. An engaging projection 61a projecting in the Ya direction is formed at the tip of the first locking projection 60a in the projection direction, i.e., the end in the Za direction.

[0060] Furthermore, as shown in Figures 4, 5, and 9(b), both the one-sided fitting projection 16a and the other-sided fitting projection 16b are provided at the Za-direction end of the first wall surface 11, similar to the first locking projection 60a.

[0061] More specifically, one side fitting projection 16a is provided adjacent to the first locking projection 60a on the side in the Xa direction, and the other side fitting projection 16b is provided adjacent to the first locking projection 60a on the side in the Xb direction. Both the one side fitting projection 16a and the other side fitting projection 16b project from their respective ends in the Za direction with the same projection length in the Za direction. The other side fitting projection 16b is formed to be wider in the X direction than the one side fitting projection 16a.

[0062] As shown in Figures 2, 4, 5, 6(b), 7(a), and 9(a), the second locking projection 60b is provided on the second locking portion 6b and is located at the end of the second wall portion 12 in the Za direction, spaced apart from the corner portion 13 in the Yb direction, and protruding in the Za direction. An engaging projection 61b protruding in the Xa direction is formed at the tip of the second locking projection 60b in the protruding direction, i.e., the end in the Za direction. The first locking portion 6a and the second locking portion 6b are arranged such that the distance in the Y direction between the second locking portion 6b and the corner portion 13 is longer than the distance in the X direction between the first locking portion 6a and the corner portion 13.

[0063] Furthermore, as shown in Figures 2 to 5, the motor mounting section 2 includes an outer cylinder holding section 21 that holds the outer cylinder section 8a of the motor 8 shown in Figure 1, a first assembly section 31 that is assembled to the first wall section 11, a second assembly section 41 that is assembled to the second wall section 12, and a corner reinforcement section 51 that linearly connects the first assembly section 31 and the second assembly section 41.

[0064] The motor mounting section 2 is assembled across the first wall section 11 and the second wall section 12 by having the first assembly section 31 assembled to the first wall section 11 and the second assembly section 41 assembled to the second wall section 12.

[0065] The outer cylinder holding portion 21 has a first protruding portion 22 that extends from the first assembly portion 31 and a second protruding portion 23 that extends from the second assembly portion 41, and is formed as an annular shape C in plan view. The outer cylinder holding portion 21 is positioned on the inner corner side of the first assembly portion 31 and the second assembly portion 41, that is, on the side in the Yb direction relative to the first assembly portion 31 and on the side in the Xb direction relative to the second assembly portion 41, and is integrally joined to the first assembly portion 31 and the second assembly portion 41 from the inner side.

[0066] The first protruding portion 22 is formed so that its protruding length from the first assembly portion 31 is longer than the protruding length of the second protruding portion 23 from the second assembly portion 41. Furthermore, the first protruding portion 22 is formed in a substantially arc shape in plan view so as to protrude in the Xb direction from the first assembly portion 31 and gradually protrude in the Yb direction toward the tip in the protruding direction.

[0067] The outer cylinder holding portion 21 is formed in a cantilever manner relative to the first assembly portion 31 and the second assembly portion 41, with the first protruding portion 22 and the second protruding portion 23 being elastically deformable in the radial direction. By utilizing the elastic force of the first protruding portion 22 and the second protruding portion 23, it firmly holds the outer cylinder portion 8a of the motor 8 by embracing it along its outer circumference.

[0068] As shown in Figures 4 and 7(a)(b), a reinforcing portion 24 is provided at the base of the first protruding portion 22 of the outer cylinder holding portion 21 in the direction of projection. The reinforcing portion 24 comprises an outer wall reinforcing portion 25 that extends continuously from the outer wall portion 36 of the first assembly portion 31 (described later) along the outer circumferential surface of the first protruding portion 22 in the direction of projection of the first protruding portion 22, and a plurality of ribs 26 that connect the outer wall reinforcing portion 25 and the first protruding portion 22. The reinforcing portion 24 reinforces the base of the first protruding portion 22 and increases the elastic force of the first protruding portion 22, thereby increasing the holding force of the motor 8 by the outer cylinder holding portion 21.

[0069] As shown in Figures 2 to 5 and Figure 7(b), the first assembly portion 31 and the second assembly portion 41 are perpendicular to each other via corner portions 20 extending along the Z direction, and as shown in Figure 7(b), adjacent ends are connected to each other, forming a shape that is approximately L-shaped when viewed from the bottom.

[0070] As shown in Figures 2 and 6(a), the first assembly portion 31 is formed along the X direction when the motor mounting portion 2 and the protective cover portion 3 are assembled, and its outer surface is formed to be substantially flush with the outer surface 11a of the first wall portion 11.

[0071] As shown in Figures 2 to 5 and Figure 6(a), the first assembly portion 31 is provided with a corner-side assembly portion 32, a first locked portion 62a provided on the first lock portion 6a, a support portion 33 that supports the first protruding portion 22 that extends from the first assembly portion 31, a one-side fitted portion 34a, a other-side fitted portion 34b, and a first protruding piece 35.

[0072] The corner assembly portion 32, the first locked portion 62a, and the support portion 33 are arranged in this order from the corner portion 13 in the Xb direction. In other words, the corner-side assembly portion 32 is provided on the side of the corner 13 relative to the first locked portion 62a in the X direction, i.e., on the Xa direction side, while the support portion 33 is provided on the side of the first locked portion 62a opposite to the corner 13 in the X direction, i.e., on the Xb direction side. The support portion 33 is formed to be longer in the X direction than the corner-side assembly portion 32.

[0073] The corner assembly portion 32 and the support portion 33 have a thickness greater than the plate thickness of the first wall portion 11. More specifically, as shown in Figures 2, 3, and 8(b), the first assembly portion 31 comprises an outer wall portion 36, an inner wall portion 37, and a rib 38, and has a thickness that allows it to be positioned across the plate thickness direction of the first wall surface portion 11. As shown in Figures 2, 4, 6(a), and 7(a)(b), the outer wall portion 36 is formed on the support portion 33 and the corner-side assembly portion 32 of the first assembly portion 31, excluding the first locked portion 62a, in the X direction. Furthermore, the outer wall portion 36 is located on the side in the Ya direction from the outer cylinder holding portion 21, that is, on the outer circumference side of the outer cylinder holding portion 21, and extends in the Z direction from the Za direction end of the first wall surface portion 11 to the Za direction end of the outer cylinder holding portion 21.

[0074] As shown in Figures 3, 5, 7(b), 8(b), and 9(a), the inner wall portion 37 is formed along the entire length of the first assembly portion 31 in the X direction. Furthermore, as shown in Figures 7(b) and 8(b), the inner wall portion 37 is positioned opposite the outer wall portion 36 on the Yb direction side, separated by the thickness of the first wall surface portion 11, and as shown in Figure 8(b), the end in the Za direction is integrally joined with the end in the Zb direction of the outer cylinder holding portion 21.

[0075] Multiple ribs 38 are provided at predetermined intervals in the X direction of the first assembly portion 31. Each of these ribs 38 connects the outer wall portion 36, the inner wall portion 37, and the outer cylinder holding portion 21 so as to straddle the first wall portion 11 in the plate thickness direction, and as shown in Figure 9(b), the end in the Zb direction is formed to be able to abut against the end in the Za direction of the first wall portion 11.

[0076] As shown in Figures 2 to 4, Figure 6(a), Figure 7(a)(b), and Figure 8(a), the first locked portion 62a extends linearly in the X direction so as to connect the outer wall portions 36 located on both sides in the X direction at the Ya direction end and the Zb direction end of the first assembly portion 31.

[0077] As shown in Figures 4, 7(b), and 8(a), a through hole 63 is provided between the first locked portion 62a and the inner wall portion 37 of the first assembly portion 31, through which the first locking projection 60a can be inserted in the Z direction. The first locking portion 6a fixes the first wall portion 11 and the first assembly portion 31 by engaging the engaging projection 61a with the first locked portion 62a while the first locking projection 60a on the side of the first wall portion 11 is fitted into the through hole 63.

[0078] As shown in Figures 7(b) and 9(b), the one-sided fitting portion 34a is formed hollow inside the corner-side assembly portion 32 by an inner wall portion 37, an outer wall portion 36, and a rib 38, and the one-sided fitting projection 16a is formed to open in the Zb direction so that it can be fitted in the Za direction.

[0079] As shown in Figures 7(b), 8(b), and 9(b), the other side fitting portion 34b is formed hollow inside the support portion 33 by an inner wall portion 37, an outer wall portion 36, and a rib 38, and is formed with an opening in the Zb direction so that the other side fitting projection 16b can be fitted in the Za direction.

[0080] As shown in Figure 9(a), the first protruding piece 35 is formed along the entire length of the inner wall portion 37 in the X direction. Furthermore, as shown in Figures 3, 5, 7(b), 8(a)(b), and 9(a), the first protruding piece 35 is formed to protrude in the Zb direction from the Zb end of the inner wall portion 37 so as to be able to abut the inner surface 11b of the first wall surface portion 11 in the thickness direction.

[0081] Furthermore, as shown in Figures 2 to 5, 6(b), 7(a)(b), 8(a)(b), and 9(a), the second assembly portion 41 is formed in a plate shape along the Y direction, and as shown in Figures 6(b) and 9(a), it is provided with a second locked portion 62b attached to the second locking portion 6b and a second protruding piece 42.

[0082] The second locking portion 62b is formed to protrude in a frame shape in plan view from the end face in the Xa direction of the second assembly portion 41, i.e., from the outer surface in the Xa direction. As shown in Figures 4, 7(b), and 9(a), a through hole 64 is provided between the second locking portion 62b and the outer surface of the second assembly portion 41, through which the second locking projection 60b can be fitted into. The second locking portion 6b then fixes the second wall portion 12 and the second assembly portion 41 by engaging the engaging projection 61b with the second locking portion 62b when the second locking projection 60b is fitted into the through hole 64.

[0083] As shown in Figures 6(a) and 6(b), the first locking portion 6a and the second locking portion 6b are arranged such that the distance Lx in the X direction between the first locking portion 6a and the harness fixing portion 17 is longer than the distance Ly in the Y direction between the second locking portion 6b and the harness fixing portion 17. Furthermore, as shown in Figures 3 to 5, Figure 7(b), and Figure 9(a), the second protruding piece 42 is formed to protrude in the Zb direction so as to be able to abut against the inner surface 12b of the second wall portion 12 in the thickness direction. As shown in Figures 3, 5, and 7(b), the first protruding piece 35 of the first assembly portion 31 and the second protruding piece 42 of the second assembly portion 41 are perpendicular to each other via corner portions 20 that extend along the Z direction, and adjacent ends are connected to each other.

[0084] As shown in Figures 3 and 5, the second protruding piece 42 is formed to have a longer protruding length in the Zb direction than the first protruding piece 35. Furthermore, the protruding portion 43 of the second protruding piece 42 that protrudes in the Zb direction from the first protruding piece 35 is provided with a flange portion 44 that protrudes in the Xb direction from the Ya direction end of the protruding portion 43. The flange portion 44 is formed along the entire length of the protruding portion 43 in the Z direction. The Za direction end of the flange portion 44 is formed integrally with the first protruding piece 35.

[0085] By providing a flange portion 44 formed along the Z direction at the Ya direction end of the protruding portion 43, the corner portion 20 of the motor mounting portion 2 is formed as a ridge line extending in the Z direction, continuously from the portion between the first assembly portion 31 and the second assembly portion 41 to the Zb direction end of the second protruding piece 42.

[0086] As shown in Figure 9(a), the transverse ribs 14x and longitudinal ribs 14y formed on the inner surface 11b of the first wall portion 11 described above are formed in a gate shape when viewed from the front. More specifically, the transverse rib 14x described above is provided on the inner surface 11b of the first wall portion 11 so as to be able to contact the tip of the first protruding piece 35 in the protruding direction, on the side in the Za direction of the second protruding piece 42.

[0087] Furthermore, the aforementioned longitudinal ribs 14y (14ya, 14yb) are provided in pairs on the inner surface 11b of the first wall portion 11, extending parallel to each other in the Z direction with a gap in the X direction between them, and both extend in the Z direction from the position of the tip of the second protruding piece 42 in the protruding direction to the position in the Za direction and the position in the Zb direction. Of the pair of longitudinal ribs 14ya, 14yb, the longitudinal rib 14ya at the end in the Xa direction has its end in the Za direction connected to the end of the transverse rib 14x in the Xa direction, and the longitudinal rib 14yb at the end in the Xb direction has its end in the Za direction connected to the end of the transverse rib 14x in the Xb direction.

[0088] As shown in Figures 3, 5, 7(b), 8(a)(b), and 9(a), the corner reinforcement portion 51 is positioned on the inner corner side between the first assembly portion 31 and the second assembly portion 41, and is positioned adjacent to the outer cylinder holding portion 21 on the side in the Zb direction relative to the outer cylinder holding portion 21.

[0089] As shown in Figures 7(b) and 8(a), the corner reinforcement portion 51 has its end portion 51x in the Ya and Xb directions connected to the first assembly portion 31 from the inner corner side of the first assembly portion 31 and the second assembly portion 41 at a location corresponding to the first lock portion 6a in the X direction. As shown in Figures 7(b) and 9(a), the corner reinforcement portion 51 has its end portion 51y in the Yb and Xa directions connected to the second assembly portion 41 from the inner corner side of the first assembly portion 31 and the second assembly portion 41 at a location corresponding to the second lock portion 6b in the Y direction.

[0090] In the above-described embodiment, the motor cover 1 integrates the separately formed motor mounting portion 2 and protective cover portion 3, thereby preventing unintended deformation due to external forces. More specifically, as shown in Figures 2 and 3, the motor cover 1 is assembled such that the motor mounting portion 2 straddles the first wall portion 11 and the second wall portion 12 of the protective cover portion 3, with the motor mounting portion 2 and the protective cover portion 3 being fixed together by the first lock portion 6a and the second lock portion 6b.

[0091] Therefore, even if an unintended external force acts on the protective cover portion 3 and the motor mounting portion 2, the motor mounting portion 2 and the protective cover portion 3 can be assembled while suppressing relative deformation.

[0092] For example, by suppressing inward tilting deformation of the motor mounting portion 2 relative to the protective cover portion 3, it is possible to prevent the motor mounting portion 2 and the protective cover portion 3 from unintentionally interfering with the harness 7.

[0093] Furthermore, as shown in Figures 8(a)(b), 9(a), etc., the motor cover 1 of this embodiment is equipped with a first protruding piece 35 on the motor mounting portion 2 that protrudes in the Zb direction so as to be able to abut against the inner surface 11b of the first wall portion 11 in the thickness direction. Therefore, even if an external force acts on the motor mounting portion 2 in a direction that causes the motor mounting portion 2 to tilt inward relative to the first wall portion 11, the first protruding piece 35 abuts against the inner surface 11b of the first wall portion 11, thereby preventing the motor mounting portion 2 from tilting inward relative to the first wall portion 11.

[0094] Furthermore, as shown in Figure 9(a), the motor cover 1 of this embodiment is equipped with a second protruding piece 42 on the motor mounting portion 2 that protrudes in the Zb direction so as to be able to abut against the inner surface 12b of the second wall portion 12 in the thickness direction. Therefore, even if an external force acts on the motor mounting portion 2 in a direction that causes the motor mounting portion 2 to tilt inward relative to the second wall portion 12, the second protruding piece 42 abuts against the inner surface 12b of the second wall portion 12, thereby preventing the motor mounting portion 2 from tilting inward relative to the second wall portion 12.

[0095] In this case, if an external force is applied to the first protruding portion 22 of the outer cylinder holding portion 21, which has a longer protruding length than the second protruding portion 23, the bending stress that causes the motor mounting portion 2 to deform inward relative to the second wall surface portion 12 may be greater than the bending stress that causes it to deform inward relative to the first wall surface portion 11.

[0096] In contrast, in this embodiment, as shown in Figures 3, 5, and 9(a), the second protruding piece 42 is formed to have a longer protruding length in the Zb direction than the first protruding piece 35, thereby effectively suppressing the inward tilting deformation described above.

[0097] Furthermore, as shown in Figure 3, the protruding portion 43 of the second protruding piece 42 that protrudes in the Zb direction from the first protruding piece 35 has a flange portion 44 that protrudes in the Xb direction from the end in the Ya direction, extending along the entire length of the protruding portion 43 in the Z direction. As a result, the corner portion 20 between the first assembly portion 31 and the second assembly portion 41 of the motor mounting portion 2 can be formed as a ridge line that extends continuously to the tip of the second protruding piece 42 in the protruding direction. Therefore, the strength of the first protruding piece 35 and the second protruding piece 42 can be mutually increased, so that the motor mounting portion 2 can resist external forces that cause it to deform inward relative to the first wall portion 11 and the second wall portion 12.

[0098] Furthermore, as shown in Figures 3, 5, 8(b), and 9, the first wall portion 11 can be reinforced by transverse ribs 14x extending in the X direction. Therefore, even if an unintended external force acts on the protective cover portion 3 equipped with the first wall portion 11, the harness 7 can be securely protected by the protective cover portion 3.

[0099] Furthermore, since the transverse rib 14x is provided so as to be able to abut against the tip of the first protruding piece 35 in the protruding direction, even if an external force acts on the motor mounting portion 2 in a direction that causes it to tilt inward relative to the second wall portion 12, the tip of the first protruding piece 35 in the protruding direction abuts against the transverse rib 14x that reinforces the first wall portion 11, thereby resisting the external force. Therefore, inward tilting deformation of the motor mounting portion 2 relative to the second wall portion 12 can be further prevented.

[0100] In addition, even when an external force acts on the motor mounting portion 2 in a direction that causes it to tilt inward relative to the first wall portion 11, the transverse rib 14x is formed so that the tip of the first protruding piece 35 in the protruding direction can come into contact with it, thereby further preventing the motor mounting portion 2 from tilting inward relative to the first wall portion 11.

[0101] Furthermore, as shown in Figure 9, the first wall portion 11 can be reinforced over a wide area in the Z direction by a longitudinal rib 14y extending across the Z direction of the tip of the second protruding piece 42 on the inner surface 11b of the first wall portion 11. Therefore, the protective cover portion 3 can firmly protect the harness 7 against unwanted external forces.

[0102] Furthermore, even if the tip of the first protruding piece 35 in the protruding direction comes into contact with the transverse rib 14x, the transverse rib 14x can be supported by the longitudinal rib 14y. Therefore, the transverse rib 14x can resist even more effectively external forces that would cause the motor mounting portion 2 to tilt inward relative to the second wall portion 12.

[0103] Furthermore, as shown in Figures 2 and 8(b), the first assembly portion 31 is provided with a support portion 33 that spans the thickness direction of the first wall portion 11 and is positioned on the opposite side of the corner portion 13 from the first lock portion 6a in the first direction. Therefore, even if an external force acts on the motor mounting portion 2 in a direction that causes it to tilt inward relative to the second wall portion 12, the support portion 33 can resist the external force by contacting the end face of the first wall portion 11 in the Za direction, and as a result, the inward tilting deformation of the motor mounting portion 2 can be prevented.

[0104] Furthermore, as shown in Figure 9(b), the protective cover portion 3 and the motor mounting portion 2 can be more securely fixed together because, in addition to the fixing of the first lock portion 6a and the second lock portion 6b, the fitting projection 16a on one side and the fitted portion 34a on one side, and the fitting projection 16b on the other side and the fitted portion 34b on the other side also fit together.

[0105] Furthermore, even if an external force acts on the motor mounting portion 2 in a direction that causes it to tilt inward relative to the first wall portion 11, the engagement of one side fitting projection 16a and one side fitted portion 34a, and the engagement of the other side fitting projection 16b and the other side fitted portion 34b, makes it possible to more reliably prevent the motor mounting portion 2 from tilting inward relative to the first wall portion 11.

[0106] Furthermore, since one side fitting projection 16a and one side fitted portion 34a engage with the first locking portion 6a on the Xa side, and the other side fitting projection 16b and the other side fitted portion 34b engage with the first locking portion 6a on the Xb side, the motor mounting portion 2 can resist external forces that cause the motor mounting portion 2 to deform inward relative to the first wall portion 11, together with the first locking portion 6a, from both sides of the first locking portion 6a.

[0107] In particular, the other side fitting projection 16b and the other side fitted portion 34b engage with the support portion 33 on the Xb direction side relative to the first locking portion 6a, thereby making the hollow support portion 33 substantially solid due to the arrangement of the other side fitting projection 16b inside. Consequently, the support strength of the first protruding portion 22 by the support portion 33 can be increased.

[0108] Furthermore, as shown in Figure 3, by connecting the first assembly part 31, which is attached to the first wall surface part 11, and the second assembly part 41, which is attached to the second wall surface part 12, with the corner reinforcement part 51, it is possible to prevent unintended deformation such as changes in the angle of the corner part 13 of the motor mounting part 2 in response to an unintended external force.

[0109] Furthermore, when assembling the motor mounting section 2 and the protective cover section 3 in the Z direction, the worker presses the motor mounting section 2 in the Zb direction, that is, towards the protective cover section 3. At that time, the corner reinforcement section 51 can receive the external force in the Zb direction applied to the outer cylinder holding section 21 from the Zb direction side relative to the outer cylinder holding section 21. As a result, the outer cylinder holding section 21, which is positioned on the inner corner side relative to the first assembly section 31 and the second assembly section 41, can be supported by the corner reinforcement section 51.

[0110] Furthermore, in the motor mounting portion 2 of this embodiment, where the arc-shaped outer cylinder holding portion 21 is joined to the L-shaped first assembly portion 31 and second assembly portion 41, a space, i.e., a dead space, is created between the assembly portions 31, 41 and the outer cylinder holding portion 21 on the inner corner side of the first assembly portion 31 and the second assembly portion 41. However, since the corner reinforcement portion 51 is arranged in this space, this space can be effectively utilized.

[0111] Furthermore, as shown in Figures 3 and 8(a), the corner reinforcement portion 51 has its ends 51x in the Ya and Xb directions connected from the internal space 3s side to the portion of the first assembly portion 31 in the X direction that corresponds to the first lock portion 6a. This allows the first locking portion 6a to be reinforced even if an unintended external force acts on the motor mounting portion 2 and the protective cover portion 3.

[0112] In other words, the area of ​​the first assembly portion 31 where the first locking portion 62a in the X direction is provided does not have an outer wall portion 36 or rib 38 formed thereon, and is formed only by an inner wall portion 37 so as to be thinner than the support portion 33 and the corner side assembly portion 32. However, by connecting the Ya direction and Xb direction end portions 51x of the corner reinforcement portion 51 to the inner wall portion 37, the area where the first locking portion 62a is provided can be reinforced.

[0113] Furthermore, as shown in Figure 2, the first locking portion 6a is provided in the first assembly portion 31 at a distance from the corner portion 13, and the corner-side assembly portion 32, which is located on the corner portion 13 side relative to the first locking portion 6a, is arranged to straddle the plate thickness direction of the first wall portion 11. Therefore, the corner-side assembly portion 32 can resist an external force that causes the motor mounting portion 2 to deform outward relative to the second wall portion 12 with the first locking portion 6a as a fulcrum, by contacting the end face of the first wall portion 11 in the Za direction.

[0114] Similarly, the second locking portion 6b is provided at a portion of the second assembly portion 41 spaced apart from the corner portion 13, and the support portion 33 and corner-side assembly portion 32 of the first assembly portion 31 are arranged to straddle the plate thickness direction of the first wall portion 11. Therefore, the first assembly portion 31 can resist an external force that causes the motor mounting portion 2 to deform outward relative to the first wall portion 11 with the second locking portion 6b as a fulcrum, by contacting the end face of the first wall portion 11 in the Za direction.

[0115] In the correspondence between the configuration of this invention and the above-described embodiment, the motor corresponds to the starter motor 8, and similarly, The end of the protruding portion on the corner 13 side in the second extending direction corresponds to the end of the protruding portion on the Ya direction side, The fitting projections correspond to the fitting projection 16a on one side and the fitting projection 16b on the other side. The mating portion corresponds to one side mating portion 34a and the other side mating portion 34b, but this invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.
