Summary of the Invention

Problems to be Solved by the Invention

[0005] The power unit is disposed below the left and right front frame units. Therefore, it is difficult for the left and right front frame units to firmly support the power unit.

[0006] The present invention has been made in view of such circumstances, and an object thereof is to provide an electric saddle-riding type vehicle that firmly supports a power unit.

Means for Solving the Problems

[0007] First, it was considered to position the power unit above the down frame. Specifically, it was considered to extend the down frame to a position below the power unit. This would provide robust support for the power unit.

[0008] However, when the power unit is positioned above the down frame, a first problem arises. The first problem is, for example, a reduction in the rigidity of the main frame and the down frame. The first problem is, for example, a reduction in the rigidity of the lower part of the down frame.

[0009] Therefore, it was considered to lower the position of the connecting member even further. Specifically, it was considered to position the connecting member so that it overlaps with the power unit in a side view of the electric saddle-type vehicle. When the connecting member overlaps with the power unit in a side view of the electric saddle-type vehicle, the connecting member appropriately reinforces the main frame and the down frame. Thus, the first problem is solved.

[0010] However, a second problem arose when the power unit was positioned above the down frame and the connecting member overlapped with the power unit in a side view of the electric saddle-type vehicle. The second problem was that the power unit was difficult to attach to and detach from the electric saddle-type vehicle. The second problem was that when the power unit was attached to or detached from the electric saddle-type vehicle, it interfered with at least one of the main frame, down frame, and connecting member.

[0011] Therefore, the configuration of an electric saddle-type vehicle was further investigated. The present invention is based on these investigations. The present invention has the following configuration. In other words, the present invention is an electric saddle-type vehicle, The main frame of the aforementioned electric saddle-type vehicle extends in the front-rear direction, In a side view of the aforementioned electric saddle-type vehicle, a down frame is positioned below the main frame, In a side view of the aforementioned electric saddle-type vehicle, the power unit is positioned below the main frame and above the down frame, A first connecting member connected to the main frame and the down frame, Equipped with, The first connecting member overlaps with the power unit in a side view of the electric saddle-type vehicle.

[0013] The electric saddle-type vehicle is equipped with a first connecting member. The first connecting member is connected to the main frame and the down frame. In a side view of the electric saddle-type vehicle, the first connecting member overlaps with the power unit. Therefore, the first connecting member appropriately reinforces the main frame and the down frame. Thus, the main frame and the down frame have appropriate rigidity.

[0014] The first connecting member is detachable from the main frame and down frame. When the first connecting member is detached from the main frame and down frame, it does not overlap with the power unit in a side view of the electric saddle-type vehicle. Therefore, when the first connecting member is detached from the main frame and down frame, the power unit can be attached to and detached from the electric saddle-type vehicle without interfering with the first connecting member. Thus, the power unit can be easily attached to and detached from the electric saddle-type vehicle.

[0015] As described above, this electric saddle-type vehicle provides robust support for the power unit. Furthermore, it provides appropriate rigidity to the main frame and down frame. In addition, this electric saddle-type vehicle allows for easy attachment and detachment of the power unit.

Even when the main frame and the down frame surround the power unit in a side view of the electric saddle-riding type vehicle, the power unit can be easily attached to and detached from the electric saddle-riding type vehicle. This is because the first connecting member is removable from the main frame and the down frame. Rather, when the main frame and the down frame surround the power unit in a side view of the electric saddle-riding type vehicle, the fact that the first connecting member is removable from the main frame and the down frame is very useful.

[0019] In the electric saddle-riding type vehicle described above, the down frame has a front portion, a lower portion, and the front portion extends through a position in front of the power unit and from a position above the power unit to a position below the power unit, the lower portion extends rearward from the front portion, and the power unit is preferably disposed above the lower portion. is preferable. Therefore, the power unit is preferably disposed above the down frame.

[0021] In the electric saddle-riding type vehicle described above, the first connecting member preferably overlaps the inverter in a side view of the electric saddle-riding type vehicle. [[ID=4七十]] is preferable. The first connecting member preferably overlaps the power unit in a side view of the electric saddle-riding type vehicle.

[0022] In the above-mentioned electric saddle-type vehicle, The first connecting member supports the power unit. It is preferable. The power unit is supported more robustly.

[0023] In the above-mentioned electric saddle-type vehicle, The first connecting member is, A first part connected to the main frame, A second part connected to the down frame, A third part connected to the aforementioned power unit, Equipped with, The third part is positioned between the first part and the second part. It is preferable. The third part is positioned between the first and second parts. Therefore, the third part has appropriate rigidity. Thus, the first connecting member appropriately supports the power unit.

[0024] In the above-mentioned electric saddle-type vehicle, The first connecting member passes through the third portion and extends from the first portion to the second portion. It is preferable. Therefore, the third section has even more appropriate rigidity. Thus, the first connecting member supports the power unit more favorably.

[0025] In the above-mentioned electric saddle-type vehicle, The first connecting member is positioned either to the right of the power unit or to the left of the power unit. It is preferable. The first connecting member preferably overlaps with the power unit in a side view of the electric saddle-type vehicle.

[0026] In the above-mentioned electric saddle-type vehicle, The aforementioned electric saddle-type vehicle is A second connecting member connected to the main frame and the down frame, Equipped with, The second connecting member is positioned to the right of the power unit and to the left of the power unit, The second connecting member overlaps with the power unit in a side view of the electric saddle-type vehicle. It is preferable. Therefore, the second connecting member appropriately reinforces the main frame and the down frame. As a result, the main frame and the down frame have even more appropriate rigidity.

[0027] In the above-mentioned electric saddle-type vehicle, The second connecting member is detachable from the main frame and the down frame. It is preferable. When the second connecting member is removed from the main frame and down frame, it does not overlap with the power unit in a side view of the electric saddle-type vehicle. Therefore, when the second connecting member is removed from the main frame and down frame, the power unit can be attached to and detached from the electric saddle-type vehicle without interfering with the second connecting member. Thus, the power unit can be attached to and detached from the electric saddle-type vehicle more easily.

[0028] In the above-mentioned electric saddle-type vehicle, The aforementioned electric saddle-type vehicle is Battery and Equipped with, The first connecting member overlaps with the battery in a side view of the electric saddle-type vehicle.

When the right main frame is located to the right of the battery and the left main frame is located to the left of the battery, the distance between the right and left main frames in the width direction of the electric saddle-type vehicle is relatively large. However, even when the right main frame is located to the right of the battery and the left main frame is located to the left of the battery, the main frame has adequate rigidity. This is because the first connecting member is connected to the main frame and the down frame, and the first connecting member overlaps with the power unit in a side view of the electric saddle-type vehicle. Rather, when the right main frame is located to the right of the battery and the left main frame is located to the left of the battery, the first connecting member is very useful.

Therefore, when attaching or detaching the battery to an electric saddle-type vehicle, the direction of movement of the battery is in the vertical direction of the electric saddle-type vehicle. As described above, the power unit is attached to and detached from the electric saddle-type vehicle by moving in the width direction of the electric saddle-type vehicle relative to the main frame and down frame. In other words, when attaching or detaching the power unit to an electric saddle-type vehicle, the direction of movement of the power unit is in the width direction of the electric saddle-type vehicle. Therefore, the direction of movement of the power unit when attaching or detaching the power unit to an electric saddle-type vehicle is different from the direction of movement of the battery when attaching or detaching the battery to an electric saddle-type vehicle. Thus, the power unit can be attached to and detached from the electric saddle-type vehicle without interfering with the battery. Consequently, the power unit can be attached to and detached from the electric saddle-type vehicle more easily. Similarly, the battery can be attached to and detached from the electric saddle-type vehicle without interfering with the power unit. Consequently, the battery can be easily attached to and detached from the electric saddle-type vehicle. [Effects of the Invention]

The longitudinal direction X, width direction Y, and vertical direction Z are defined relative to the driver (also called the rider) riding in the electric saddle-type vehicle 1. The longitudinal direction X, width direction Y, and vertical direction Z are orthogonal to each other. The longitudinal direction X and width direction Y are horizontal. The vertical direction Z is vertical.

[0035] "Forward," "rearward," "upward," "downward," "right," and "left" refer to the direction in front of, behind, upward, downward, right, and left, respectively, from the perspective of the driver riding in the electric saddle-type vehicle 1. Unless otherwise specified in this specification, "forward" and "rearward" include not only directions parallel to the longitudinal direction X, but also directions close to the longitudinal direction X. Directions close to the longitudinal direction X are, for example, directions with an angle of 45 degrees or less with respect to the longitudinal direction X. Similarly, unless otherwise specified, "right" and "left" include not only directions parallel to the width direction Y, but also directions close to the width direction Y. Unless otherwise specified, "upward" and "downward" include not only directions parallel to the up-down direction Z, but also directions close to the up-down direction Z. In each figure, FRONT, REAR, UP, DOWN, RIGHT, and LEFT are shown as appropriate for reference.

[0151] <5. Connecting member 13> Figure 8 is a left side view of the vehicle frame 3, battery 41, and power unit 51. Figure 9 is a right side view of the vehicle frame 3, battery 41, and power unit 51. In Figures 8 and 9, the connecting member 13 has been removed from the main frame 5 and the down frame 6.

[0152] The connecting member 13 is detachable from the main frame 5 and the down frame 6. The connecting member 13 is separable from the main frame 5 and the down frame 6. The connecting member 13 is detachable from the main frame 5 and the down frame 6.

[0153] Specifically, the right connecting member 13R is detachable from the right main frame 5R and the down frame 6. The right connecting member 13R is separable from the right main frame 5R and the down frame 6. The right connecting member 13R is detachable from the right main frame 5R and the down frame 6. The left connecting member 13L is detachable from the left main frame 5L and the down frame 6. The left connecting member 13L is separable from the left main frame 5L and the down frame 6. The left connecting member 13L is detachable from the left main frame 5L and the down frame 6.

[0154] Furthermore, the connecting member 13 is detachable from the power unit 51. The connecting member 13 is separable from the power unit 51. The connecting member 13 is detachable from the power unit 51.

[0155] Specifically, the right connecting member 13R is detachable from the power unit 51. The right connecting member 13R is separable from the power unit 51.

The left connecting member 13L is separable from the power unit 51. The left connecting member 13L is detachable from the power unit 51.

[0156] When the connecting member 13 is removed from the main frame 5 and the down frame 6, the connecting member 13 does not overlap with the power unit 51 in a side view of the vehicle. Therefore, when the connecting member 13 is removed from the main frame 5 and the down frame 6, the first connecting member 13 allows the power unit 51 to move in the width direction Y relative to the main frame 5 and the down frame 6. For convenience, the space between the main frame 5 and the down frame 6 is referred to as the internal space. For example, when the right connecting member 13R is removed from the main frame 5 and the down frame 6, the right connecting member 13R allows the power unit 51 to move to the right from the internal space. For example, when the left connecting member 13L is removed from the main frame 5 and the down frame 6, the left connecting member 13L allows the power unit 51 to move to the left from the internal space.

[0157] On the other hand, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 overlaps with the power unit 51 in a side view of the vehicle. For this reason, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the first connecting member 13 prevents the power unit 51 from moving in the width direction Y relative to the main frame 5 and the down frame 6. For example, when the right connecting member 13R is attached to the main frame 5 and the down frame 6, the right connecting member 13R prevents the power unit 51 from moving to the right from the internal space. For example, when the left connecting member 13L is attached to the main frame 5 and the down frame 6, the left connecting member 13L prevents the power unit 51 from moving to the left from the internal space.

[0165] Furthermore, the head pipe 4 and the main frame 5 are connected, for example, by welding. Therefore, the head pipe 4 and the main frame 5 are inseparable from each other. Similarly, the head pipe 4 and the down frame 6 are connected, for example, by welding. Therefore, the head pipe 4 and the down frame 6 are also inseparable from each other. Consequently, the main frame 5 and the down frame 6 are inseparable from each other.

[0166] Furthermore, the mainframe 5, downframe 6, and pivot frame 10 are inseparable from each other.

[0167] Furthermore, the main frame 5, the down frame 6, and the reinforcing frame 12 are inseparable from each other.

[0168] The pivot shaft portion 11 is, for example, detachable from the pivot frame 10.

[0169] <6. Procedure for attaching and detaching the battery 41 and power unit 51 to the electric saddle-type vehicle 1> Figure 10 is a plan view of the vehicle frame 3 and the power unit 51. Figure 11 is a plan view illustrating the procedure for attaching and detaching the power unit 51 to the vehicle frame 3. Figure 12 is a front view illustrating the procedure for attaching and detaching the battery 41 and the power unit 51 to the vehicle frame 3. The procedure for removing the power unit 51 from the electric saddle-type vehicle 1 includes a first step, a second step, and a third step.

[0170] Step 1 The battery 41 is removed from the vehicle frame 3. Specifically, the connection between the battery 41 and a bracket (not shown) is released. Then, the battery 41 is moved upward relative to the main frame 5. The battery 41 passes between the right main frame 5R and the left main frame 5L. The battery 41 passes between the right reinforcing frame 12R and the left reinforcing frame 12L. The battery 41 passes between the right connecting member 13R and the left connecting member 13L. The battery 41 is moved to a position above the main frame 5. As a result, the battery 41 is removed from the electric saddle-type vehicle 1.

[0171] Figure 12 shows the battery 41 removed from the vehicle frame 3. The entire battery 41 is located outside the electric saddle-type vehicle 1. For example, the entire battery 41 is located above the vehicle frame 3. Since the battery 41 has been removed from the electric saddle-type vehicle 1, the battery 41 is not shown in Figures 10 and 11.

[0172] Step 2 Remove the connecting member 13 from the main frame 5 and the down frame 6. Specifically, remove the fastening member 17 to release the connection between the main frame 5 and the connecting member 13. Then, separate the connecting member 13 from the main frame 5. Remove the fastening member 18 to release the connection between the down frame 6 and the connecting member 13. Then, separate the connecting member 13 from the down frame 6.

[0173] Furthermore, the connecting member 13 is removed from the power unit 51. Specifically, the fastening member 19 is removed to release the connection between the power unit 51 and the connecting member 13. Then, the connecting member 13 is separated from the power unit 51.

[0174] Since the connecting member 13 has been removed from the main frame 5 and the down frame 6, the connecting member 13 is not shown in Figure 10-12. After the connecting member 13 has been removed from the main frame 5 and the down frame 6, the connecting member 13 does not overlap with the power unit 51 in a side view of the vehicle. Therefore, the first connecting member 13 allows the power unit 51 to move in the width direction Y relative to the main frame 5 and the down frame 6.

[0175] Step 3 The connection between the power unit 51 and the bracket 9 is released. The connection between the power unit 51 and the pivot shaft portion 11 is released. Then, the power unit 51 is removed from the vehicle frame 3. Specifically, the power unit 51 is moved in the width direction Y relative to the main frame 5 and the down frame 6. The power unit 51 is moved in the width direction Y from the internal space between the main frame 5 and the down frame 6. For example, the power unit 51 may be moved to the right relative to the main frame 5 and the down frame 6. Alternatively, the power unit 51 may be moved to the left relative to the main frame 5 and the down frame 6. The power unit 51 is moved to the outside of the internal space. As a result, the power unit 51 is removed from the electric saddle-type vehicle 1.

[0176] Figure 12 shows the power unit 51 removed from the vehicle frame 3. The entire power unit 51 is located outside the electric saddle-type vehicle 1. The entire power unit 51 is located outside the internal space. For example, the entire power unit 51 is located to the right of the vehicle frame 3. Alternatively, the entire power unit 51 is located to the left of the vehicle frame 3. Figure 12 shows the power unit 51 located to the right of the vehicle frame 3 with a solid line. Figure 12 shows the power unit 51 located to the left of the vehicle frame 3 with a dashed line.

[0177] The procedure for attaching the power unit 51 to the vehicle frame 3 is the reverse of the procedure for removing the power unit 51 from the vehicle frame 3. The procedure for attaching the power unit 51 to the electric saddle-type vehicle 1 includes steps 4, 5, and 6.

[0178] Step 4 In the fourth step, the connecting member 13 remains detached from the main frame 5 and the down frame 6. Therefore, in the fourth step, the first connecting member 13 allows the power unit 51 to move in the width direction Y relative to the main frame 5 and the down frame 6.

[0179] In the fourth step, the power unit 51 is mounted on the vehicle frame 3. Specifically, the power unit 51 is moved in the width direction Y toward the main frame 5 and the down frame 6. For example, if the power unit 51 is located to the right of the main frame 5 and the down frame 6, the power unit 51 is moved to the left. For example, if the power unit 51 is located to the left of the main frame 5 and the down frame 6, the power unit 51 is moved to the right. The power unit 51 is installed in the internal space between the main frame 5 and the down frame 6. In this way, the power unit 51 is mounted on the electric saddle-type vehicle 1.

[0180] Step 5 The connecting member 13 is attached to the main frame 5 and the down frame 6. Specifically, the main frame 5 and the connecting member 13 are connected by fastening member 17. The down frame 6 and the connecting member 13 are connected by fastening member 18. In this way, the connecting member 13 is fastened to the main frame 5 and the down frame 6.

[0181] Furthermore, the connecting member 13 is attached to the power unit 51. Specifically, the power unit 51 and the connecting member 13 are connected by the fastening member 19. In this way, the connecting member 13 is fastened to the power unit 51.

[0182] After the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 overlaps with the power unit 51 in a side view of the vehicle. Therefore, the first connecting member 13 prevents the power unit 51 from moving in the width direction Y relative to the main frame 5 and the down frame 6.

[0183] Furthermore, the power unit 51 is connected to the bracket 9. The power unit 51 is connected to the pivot shaft portion 11. In this way, the power unit 51 is attached to the electric saddle-type vehicle 1.

[0184] Step 6 The battery 41 is mounted on the vehicle frame 3. Specifically, the battery 41 is moved from its position above the main frame 5. The battery 41 is moved toward the main frame 5. The battery 41 is moved downward relative to the main frame 5. The battery 41 passes between the right main frame 5R and the left main frame 5L. The battery 41 passes between the right reinforcing frame 12R and the left reinforcing frame 12L. The battery 41 passes between the right connecting member 13R and the left connecting member 13L. The battery 41 is installed between the right main frame 5R and the left main frame 5L. In this way, the battery 41 is mounted on the electric saddle-type vehicle 1.

[0185] The battery 41 is then connected to a bracket (not shown). That is, the battery 41 is supported on the vehicle frame 3 via the bracket (not shown). In this way, the battery 41 is mounted on the electric saddle-type vehicle 1.

[0186] As described above, the battery 41 is attached to and detached from the electric saddle-type vehicle 1 by moving the battery 41 in the vertical direction Z relative to the main frame 5.

[0187] The power unit 51 is attached to and detached from the electric saddle-type vehicle 1 by moving in the width direction Y relative to the main frame 5 and the down frame 6.

[0188] <7. Effects> The electric saddle-type vehicle 1 comprises a main frame 5, a down frame 6, and a power unit 51. The main frame 5 extends in the longitudinal direction X. The down frame 6 is positioned below the main frame 5 in a side view of the vehicle. The power unit 51 is positioned below the main frame 5 and above the down frame 6 in a side view of the vehicle. Thus, the power unit 51 is robustly supported.

[0189] The electric saddle-type vehicle 1 is equipped with a connecting member 13. The connecting member 13 is connected to the main frame 5 and the down frame 6. In a side view of the vehicle, the connecting member 13 overlaps with the power unit 51. Specifically, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 overlaps with the power unit 51 in a side view of the vehicle. Therefore, the connecting member 13 appropriately reinforces the main frame 5 and the down frame 6. Thus, the main frame 5 and the down frame 6 have appropriate rigidity.

[0190] The connecting member 13 is detachable from the main frame 5 and the down frame 6. When the connecting member 13 is detached from the main frame 5 and the down frame 6, the connecting member 13 does not overlap with the power unit 51 in a side view of the vehicle. Therefore, when the connecting member 13 is detached from the main frame 5 and the down frame 6, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the first connecting member 13. Thus, the power unit 51 can be easily attached to and detached from the electric saddle-type vehicle 1.

[0191] As described above, the electric saddle-type vehicle 1 provides robust support for the power unit 51. Furthermore, the electric saddle-type vehicle 1 provides appropriate rigidity to the main frame 5 and the down frame 6. In addition, the electric saddle-type vehicle 1 allows for easy attachment and detachment of the power unit 51.

[0192] As described above, the main frame 5 is positioned above the power unit 51, and the down frame 6 is positioned below the power unit 51. Therefore, the separation distance between the main frame 5 and the down frame 6 in the vertical Z direction is relatively large. However, even when the main frame 5 is positioned above the power unit 51 and the down frame 6 is positioned below the power unit 51, the main frame 5 and the down frame 6 have appropriate rigidity. This is because the connecting member 13 is connected to the main frame 5 and the down frame 6, and the connecting member 13 overlaps with the power unit 51 in a side view of the vehicle. In fact, when the main frame 5 is positioned above the power unit 51 and the down frame 6 is positioned below the power unit 51, the connecting member 13 is very useful.

[0193] When the connecting member 13 is removed from the main frame 5 and the down frame 6, the first connecting member 13 allows the power unit 51 to move in the width direction Y relative to the main frame 5 and the down frame 6. Therefore, when the first connecting member 13 is removed from the main frame 5 and the down frame 6, it is easy for the power unit 51 to move in the width direction Y relative to the main frame 5 and the down frame 6. By moving the power unit 51 in the width direction Y relative to the main frame 5 and the down frame 6, the power unit 51 is attached to and detached from the electric saddle-type vehicle 1. Thus, when the first connecting member 13 is removed from the main frame 5 and the down frame 6, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 even more easily.

[0194] The electric saddle-type vehicle 1 is equipped with fastening members 17 and 18. Fastening member 17 connects and disconnects the main frame 5 and the connecting member 13. Fastening member 18 connects and disconnects the down frame 6 and the connecting member 13. Therefore, it is easy to attach the connecting member 13 to the main frame 5 and the down frame 6. It is also easy to remove the connecting member 13 from the main frame 5 and the down frame 6.

[0195] The main frame 5 and down frame 6 surround the power unit 51 in a side view of the vehicle. Even when the main frame 5 and down frame 6 surround the power unit 51 in a side view of the vehicle, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the main frame 5 or down frame 6. In other words, even when the main frame 5 and down frame 6 surround the power unit 51 in a side view of the vehicle, the power unit 51 can be easily attached to and detached from the electric saddle-type vehicle 1. This is because the connecting member 13 is detachable from the main frame 5 and down frame 6. In fact, when the main frame 5 and down frame 6 surround the power unit 51 in a side view of the vehicle, it is very useful that the first connecting member 13 is detachable from the main frame 5 and down frame 6.

[0196] The down frame 6 has a front portion 7 and a lower portion 8. The front portion 7 is positioned in front of the power unit 51. The front portion 7 passes in front of the power unit 51 and extends from a position above the power unit 51 to a position below the power unit 51. The lower portion 8 extends rearward from the front portion 7. The lower portion 8 is positioned below the power unit 51. The power unit 51 is positioned above the lower portion 8. Therefore, the power unit 51 is preferably positioned above the down frame 6.

[0197] The power unit 51 comprises an inverter 53 and an electric motor 55. Therefore, the power unit 51 is capable of generating mechanical energy from electrical energy for propelling the electric saddle-type vehicle 1. In other words, the power unit 51 is capable of generating power from electric energy for driving the electric saddle-type vehicle 1.

[0198] The connecting member 13 overlaps with the inverter 53 in a side view of the vehicle. Specifically, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 overlaps with the inverter 53 in a side view of the vehicle. For this reason, the connecting member 13 preferably overlaps with the power unit 51 in a side view of the vehicle.

[0199] The connecting member 13 supports the power unit 51. Specifically, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 supports the power unit 51. As a result, the power unit 51 is supported more securely.

[0200] The connecting member 13 comprises a first portion 14, a second portion 15, and a third portion 16. The first portion 14 is connected to the main frame 5. The second portion 15 is connected to the down frame 6. The third portion 16 is connected to the power unit 51. The third portion 16 is positioned between the first portion 14 and the second portion 15. Therefore, the third portion 16 has appropriate rigidity. For example, the third portion 16 is resistant to bending. Thus, the connecting member 13 suitably supports the power unit 51.

[0201] The connecting member 13 passes through the third portion 16 and extends from the first portion 14 to the second portion 15. Therefore, the third portion 16 has even more appropriate rigidity. Thus, the connecting member 13 supports the power unit 51 more favorably.

[0202] The right connecting member 13R is connected to the main frame 5 and the down frame 6. The right connecting member 13R is positioned to the right of the power unit 51. Specifically, when the right connecting member 13R is attached to the main frame 5 and the down frame 6, the right connecting member 13R is positioned to the right of the power unit 51. In a side view of the vehicle, the right connecting member 13R overlaps with the power unit 51. Specifically, when the right connecting member 13R is attached to the main frame 5 and the down frame 6, the right connecting member 13R overlaps with the power unit 51 in a side view of the vehicle. Therefore, the right connecting member 13R appropriately reinforces the main frame 5 and the down frame 6. Thus, the main frame 5 and the down frame 6 have appropriate rigidity.

[0203] The left connecting member 13L is connected to the main frame 5 and the down frame 6. The left connecting member 13L is positioned to the left of the power unit 51. Specifically, when the left connecting member 13L is attached to the main frame 5 and the down frame 6, it is positioned to the left of the power unit 51. In a side view of the vehicle, the left connecting member 13L overlaps with the power unit 51. Specifically, when the left connecting member 13L is attached to the main frame 5 and the down frame 6, it overlaps with the power unit 51 in a side view of the vehicle. Therefore, the left connecting member 13L appropriately reinforces the main frame 5 and the down frame 6. Thus, the main frame 5 and the down frame 6 have more appropriate rigidity.

[0204] The right connecting member 13R is detachable from the main frame 5 and the down frame 6. When the right connecting member 13R is detached from the main frame 5 and the down frame 6, it does not overlap with the power unit 51 in a side view of the vehicle. Therefore, when the right connecting member 13R is detached from the main frame 5 and the down frame 6, the right connecting member 13R allows the power unit 51 to move to the right relative to the main frame 5 and the down frame 6. When the right connecting member 13R is detached from the main frame 5 and the down frame 6, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the right connecting member 13R. Thus, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 more easily.

[0205] The left connecting member 13L is detachable from the main frame 5 and the down frame 6. When the left connecting member 13L is detached from the main frame 5 and the down frame 6, it does not overlap with the power unit 51 in a side view of the vehicle. Therefore, when the left connecting member 13L is detached from the main frame 5 and the down frame 6, the left connecting member 13L allows the power unit 51 to move to the left relative to the main frame 5 and the down frame 6. When the left connecting member 13L is detached from the main frame 5 and the down frame 6, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the left connecting member 13L. Thus, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 more easily.

[0206] When the right connecting member 13R and the left connecting member 13L are removed from the main frame 5 and down frame 6, respectively, it is easy to move the power unit 51 in both the rightward and leftward directions relative to the main frame 5 and down frame 6. Therefore, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 even more easily.

[0207] The electric saddle-type vehicle 1 is equipped with a battery 41. The connecting member 13 overlaps with the battery 41 in a side view of the vehicle. Specifically, when the connecting member 13 is attached to the main frame 5 and the down frame 6, the connecting member 13 overlaps with the battery 41 in a side view of the vehicle. Therefore, the connecting member 13 effectively protects the battery 41. For example, the connecting member 13 effectively prevents damage to the battery case.

[0208] The battery 41 is positioned above the power unit 51. The main frame 5 comprises a right main frame 5R and a left main frame 5L. The right main frame 5R is positioned to the right of the battery 41. The left main frame 5L is positioned to the left of the battery 41. Therefore, the separation distance between the right main frame 5R and the left main frame 5L in the width direction Y is relatively large. However, even when the right main frame 5R is positioned to the right of the battery 41 and the left main frame 5L is positioned to the left of the battery 41, the main frame 5 has adequate rigidity. This is because the connecting member 13 is connected to the main frame 5 and the down frame 6, and the connecting member 13 overlaps with the power unit 51 in a side view of the vehicle. Rather, the connecting member 13 is very useful when the right main frame 5R is positioned to the right of the battery 41 and the left main frame 5L is positioned to the left of the battery 41.

[0209] The power unit 51 is attached to and detached from the electric saddle-type vehicle 1 by moving in the width direction Y relative to the main frame 5 and down frame 6. That is, the direction of movement of the power unit 51 when attaching or detaching it to the electric saddle-type vehicle 1 is the width direction Y. The battery 41 is attached to and detached from the electric saddle-type vehicle 1 by moving in the vertical direction Z relative to the main frame 5. That is, the direction of movement of the battery 41 when attaching or detaching it to the electric saddle-type vehicle 1 is the vertical direction Z. Therefore, the direction of movement of the power unit 51 when attaching or detaching it to the electric saddle-type vehicle 1 is different from the direction of movement of the battery 41 when attaching or detaching it to the electric saddle-type vehicle 1. For example, the direction of movement of the power unit 51 when attaching or detaching it to the electric saddle-type vehicle 1 is perpendicular to the direction of movement of the battery 41 when attaching or detaching it to the electric saddle-type vehicle 1. Therefore, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the battery 41. Consequently, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 more easily. Similarly, the battery 41 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the power unit 51. Consequently, the battery 41 can be easily attached to and detached from the electric saddle-type vehicle 1.

[0210] The range of movement of the power unit 51 when attaching or detaching it to the electric saddle-type vehicle 1 is located below the range of movement of the battery 41 when attaching or detaching the battery 41 to the electric saddle-type vehicle 1. In other words, the range of movement of the power unit 51 when attaching or detaching it to the electric saddle-type vehicle 1 does not overlap with the range of movement of the battery 41 when attaching or detaching the battery 41 to the electric saddle-type vehicle 1. Therefore, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the battery 41. Consequently, the power unit 51 can be attached to and detached from the electric saddle-type vehicle 1 more easily. Similarly, the battery 41 can be attached to and detached from the electric saddle-type vehicle 1 without interfering with the power unit 51. Consequently, the battery 41 can be attached to and detached from the electric saddle-type vehicle 1 more easily.
