[0006] Technical problem to be solved by the utility model

[0007] In the technology described in Patent Document 1, the operating state of the clutch lever is basically detected based on the detection result of a clutch switch. Therefore, it can only detect whether the clutch lever has moved to a specified position, and the accuracy requirement for detecting the clutch lever moving to a position different from the specified position is not high.

[0008] However, depending on the vehicle, the required detection accuracy is sometimes specified.

[0009] This invention was made in view of the above circumstances, and its purpose is to provide a saddle-type vehicle that can detect with high precision whether the clutch lever has moved to the gripping or non-gripping position with a simple structure that suppresses the complexity of the configuration layout of components such as sensors.

[0010] Means for solving technical problems

[0011] A saddle-type vehicle is provided, comprising: a clutch lever; a swing shaft supporting the clutch lever for swinging; a lever pivot at which the swing shaft is disposed; and a first sensor and a second sensor having switches pressable by the clutch lever, characterized in that the first sensor is fixed to one face of the lever pivot in the swing shaft direction, and the second sensor is fixed to another face of the lever pivot in the swing shaft direction; when viewed along the axial direction of the swing shaft, the switches of the first sensor and the second sensor are arranged concentrically across the swing shaft; the switch of the first sensor is pressed when the clutch lever is moved to a gripped position, and the switch of the second sensor is pressed when the clutch lever is moved to a non-grip position.

[0012] In the above structure, one side of the clutch lever in the swing axis direction may have a first protrusion that presses the switch of the first sensor when it is moved to the gripping position, and another side of the clutch lever in the swing axis direction may have a second protrusion that presses the switch of the second sensor when it is moved to the non-gripping position. When viewed along the axial direction of the swing axis, the first protrusion and the second protrusion are arranged in a concentric circle with the swing axis between them.

[0013] Alternatively, in the above structure, a first recess is provided on one side of the lever pivot in the swing axis direction, allowing the first protrusion of the clutch lever to enter, and a second recess is provided on the other side of the lever pivot in the swing axis direction, allowing the second protrusion of the clutch lever to enter. When viewed along the axial direction of the swing axis, the first recess and the second recess are arranged in a concentric circle shape across the swing axis.

[0014] Alternatively, in the above structure, a rod cover may be tightly fitted to the rod pivot, and when the vehicle body is viewed from above, the rod cover overlaps with the first sensor and the second sensor.

[0015] Alternatively, in the above structure, the first sensor and the second sensor may have the same shape.

[0016] Utility Model Effect

[0017] It is possible to provide a saddle-type vehicle that can detect with high precision whether the clutch lever has moved to the engaged or unengaged position with a simple structure that minimizes the complexity of the configuration layout of components such as sensors.

A spacer portion 73c protruding to the right is formed on the right side of the swing shaft holes 73a1 and 73b1.

[0085] On the upper surface portion 73a, a first opening (first recess) 75 is formed at a position closer to the handle fixing portion 71 than the swing shaft hole 73a1. The first opening 75 is formed by a portion missing from the outer periphery of the swing shaft hole 73a1 in the circumferential direction from the left end to the right. In other words, the first opening 75 is a recess formed by the upper surface portion 73a recessed from the left end to the right. The first opening 75 communicates the rod receiving portion 74 with the upper surface. Corresponding to the position of the first opening 75, on the rod support portion 73, a rod abutment portion 75a is formed on the inner surface portion in the vehicle width direction corresponding to the bottom surface of the rod receiving portion 74.

[0086] A sensor mounting portion 77 is formed on the right side of the first opening 75. The sensor mounting portion 77 has: a positioning recess 77a, which is recessed downward on the upper surface portion 73a; and a boss-shaped sensor fastening portion 77b, which is located closer to the handle fixing portion 71 than the positioning recess 77a and protrudes upward.

[0090] A connecting hole 73b2 is formed on the right side of the swing shaft hole 73b1. When viewed axially from above, a portion of the connecting hole 73b2 is exposed from the first opening 75 (see reference). Figure 5 ).

[0091] Figure 9 This is a left view of the main part of the clutch lever support mechanism 63. Figure 10 This is a front view of the main part of the clutch lever support mechanism 63. Figure 9 , Figure 10 In the middle, rod cover 100 is not shown.

[0092] The clutch lever 80 has a rod-shaped lever body 81 extending in the left-right direction and a plate-shaped lever base 82 provided on the right side of the lever body 81. A slotted cable engaging portion 83 is formed at the right end of the lever body 81. The cable engaging portion 83 can hook the inner cable of the clutch cable 132 through an anti-disengagement component.

[0093] A rod base 82 is formed at the right end of the rod body 81. The rod base 82 is thinner than the rod body 81. The rod base 82 has a stepped recessed shape relative to the rod body 81. An abutment surface 81a extending in the front-rear direction is formed at the right end of the rod body 81. A pair of abutment surfaces 81a are formed on the upper and lower sides of the rod base 82. The rod base 82 is received in the rod receiving portion 74 of the left rod pivot 70. At this time, the abutment surface 81a can abut against the right surface of the rod support portion 73 of the left rod pivot 70.

[0094] A pivot shaft hole 82a extending along the thickness direction is formed in the base 82 of the rod. The pivot shaft hole 82a is formed in a corresponding position to the pivot shaft holes 73a1 and 73b1. A columnar first protrusion 85 protruding upward is formed on the handle 21 side of the pivot shaft hole 82a. The first protrusion 85 is formed on the upper surface of the base 82 of the rod (on the side in the pivot shaft direction). The first protrusion 85 protrudes to a position higher than the main body 81 of the rod. The first protrusion 85 is formed at a position where the first opening 75 of the left rod pivot 70 can be entered.

[0095] When viewed axially, a downwardly projecting columnar second protrusion 86 is formed on the side opposite to the first protrusion 85, across the swing shaft hole 82a (swing shaft 112). The second protrusion 86 is formed on the lower surface of the rod base 82 (the other side in the swing shaft direction). The second protrusion 86 protrudes to a position lower than the rod body 81. The second protrusion 86 is formed at a position where the second opening 76 of the left rod pivot 70 can be accessed.

[0096] Between the first protrusion 85 and the swing shaft hole 82a, a recess 82b extending along the swing shaft direction and recessed to the left is formed on the right surface of the rod base 82 (see reference). Figure 10 The recess 82b is formed corresponding to the position of the connecting hole 73b2 on the lower surface portion 72b of the left lever pivot 70. When the clutch lever 80 moves to the disengaged position P1, the recess 82b prevents the connecting hole 73b2 from being blocked.

[0097] A cut-off detection sensor 91 and a connection detection sensor 92 for detecting the operating state of the clutch lever 80 are respectively installed on the sensor mounting portions 77 and 78 of the left lever pivot 70. Sensors 91 and 92 are of the same shape. In this embodiment, the cut-off detection sensor 91 and the connection detection sensor 92 are sensors of the same type and specification.

[0098] like Figure 5 As shown, sensors 91 and 92 each have: a generally rectangular sensor body 93 with a thickness in the vertical direction; a pair of terminals 94 supported on the sensor body 93; and a rod-shaped switch 95 supported on the sensor body 93 in a retractable manner. The switch 95 is configured to retract in a direction orthogonal to the direction in which the pair of terminals 94 protrude from the sensor body 93.

[0099] A positioning protrusion 93a protruding in the thickness direction is formed on the sensor body 93. The positioning protrusion 93a is disposed near the switch 95. In this embodiment, when the sensor body 93 is viewed from the thickness direction, the positioning protrusion 93a overlaps with the retractable portion of the switch 95. A fixing hole 93b penetrating the sensor body 93 in the thickness direction is formed at a position separate from the positioning protrusion 93a.

[0100] A rod cover 100 is fastened to the cover fastening portion 79 of the left rod pivot 70. The rod cover 100 is shaped to cover the left rod pivot 70 from above, and is open below. The rod cover 100 has a plate-shaped upper cover surface portion 101. The upper cover surface portion 101 overlaps with the rod support portion 73 of the left rod pivot 70 when viewed axially (see reference). Figure 5 A through hole 101a extending along the thickness direction is formed on the upper surface portion 101 of the cover (see reference). Figure 7 Multiple downward-protruding portions 101c and 101d are formed on the lower surface (inner surface) of the cover surface portion 101.

[0101] An inner wall portion 102 extending downward is formed at the right end (inner end in the vehicle width direction) of the upper surface portion 101 of the cover. A cable guide portion 102a (see reference) is formed in the inner wall portion 102, which is approximately U-shaped and protrudes to the right in a semi-cylindrical shape from below upwards. Figure 4 Clutch cable 132 is discharged from cable outlet 102a in the state of entering cable outlet 102a.

[0102] A downwardly extending front surface portion 103 is formed at the front end of the upper surface portion 101. The front surface portion 103 extends downward with the same length as the inner wall portion 102. A downwardly extending outer wall portion 104 is formed at the left end (outer end in the vehicle width direction) of the upper surface portion 101. The outer wall portion 104 extends downward with a shorter length than the front surface portion 103. The rod cover 100 is secured by the protrusions 101c and 101d to easily maintain the space between the upper surface portion 101 and the rod support portion 73. The rod cover 100 covers the sensors 91 and 92 from above, the front side, and the right side.

[0103] Next, refer to Figure 7An example of the assembly of the clutch lever support mechanism 63 will be described.

[0104] The left lever pivot 70 is fixed to the handle 21. That is, the handle 21 is inserted into the handle fixing part 71, and the fastening member 111 is inserted from the front into the fastening hole 71b. By fastening the fastening member 111, the slot 71a is fastened, and the left lever pivot 70 is fixed to the handle 21 (see reference). Figure 5 , Figure 6 ).

[0105] The base 82 of the clutch lever 80 is received into the rod receiving portion 74 of the left lever pivot 70. Furthermore, a swing shaft 112 is inserted from above into the swing shaft holes 73a1 and 73b1 of the left lever pivot 70 and the swing shaft hole 82a of the clutch lever 80. In this embodiment, the swing shaft 112 is bolt-shaped, and a fixing nut 113 is fastened to the lower end of the swing shaft 112. Thus, the clutch lever 80 is supported on the left lever pivot 70 in a swingable manner. That is, it is supported at a connection position P0 (see reference) where the abutment surface 81a of the clutch lever 80 abuts against the rod support portion 73 of the left lever pivot 70. Figure 11 , Figure 12 The cut-off position P1 where the first protrusion 85 of the clutch lever 80 abuts against the lever abutment 75a (refer to) Figure 11 , Figure 12 The clutch lever 80 swings between the two openings. At this time, the first protrusion 85 of the clutch lever 80 passes through the first opening 75 and protrudes above the lever support 73. Additionally, the second protrusion 86 of the clutch lever 80 passes through the second opening 76 and protrudes below the lever support 73.

[0106] A cylindrical connector 114 is fixed to the cable outlet hole 74a of the left pivot 70. (Example) Figure 5 , Figure 6 As shown, the outer cable 132a of the clutch cable 132 is fixed at the connector 114. In addition, the inner cable inside the outer cable 132a passes through the connector 114 and is engaged with the cable engagement portion 83 of the clutch lever 80 via the anti-disengagement component.

[0107] The cut-off detection sensor 91 is mounted on the sensor mounting portion 77 of the left rod pivot 70. Specifically, regarding the cut-off detection sensor 91, the positioning protrusion 93a is inserted into the positioning recess 77a of the sensor mounting portion 77, and the fixing hole 93b is aligned with the sensor fastening portion 77b of the sensor mounting portion 77. Furthermore, the fastening member 115 is inserted from above into the fixing hole 93b, and the fastening member 115 is fastened to the sensor fastening portion 77b. Thus, the cut-off detection sensor 91 is mounted on the sensor mounting portion 77 of the left rod pivot 70. At this time, when viewed axially from above (refer to...),... Figure 5When the cut-off detection sensor 91 is activated, its terminal 94 is located on the side furthest from the handle 21 than the spacer 73c. ​​Furthermore, the switch 95 of the cut-off detection sensor 91 is located within the first opening 75. The switch 95 of the cut-off detection sensor 91 can be pressed into place using the first protrusion 85 of the clutch lever 80.

[0108] The connection detection sensor 92 is mounted on the sensor mounting portion 78 of the left rod pivot 70. Specifically, regarding the connection detection sensor 92, the positioning protrusion 93a is inserted into the positioning recess 78a of the sensor mounting portion 78, and the fixing hole 93b is aligned with the sensor fastening portion 78b of the sensor mounting portion 78. Furthermore, the fastening member 116 is inserted from below into the fixing hole 93b, and the fastening member 116 is fastened to the sensor fastening portion 78b. Thus, the connection detection sensor 92 is mounted on the sensor mounting portion 78 of the left rod pivot 70. At this time, when viewed axially from below (refer to...),... Figure 6 When connected, the terminal 94 of the sensor 92 is located on the side closer to the handle 21 than the spacer 73c. ​​Furthermore, the switch 95 of the sensor 92 is located within the second opening 76. The switch 95 of the sensor 92 can be pressed into place using the second protrusion 86 of the clutch lever 80.

[0109] Cable 133 is connected to terminals 94 of cut detection sensor 91 via a pair of connectors 133a. After extending forward from cut detection sensor 91, cable 133 passes over connector 114 and bends downward in a U-shape from the front side of connector 114, extending rearward. When cable 133 is bent rearward, viewed axially from below (refer to...) Figure 6 The cable 133 extends rearward in a manner that overlaps with the lower part of the connector 114 and the spacer 73c, and is guided into the left handle switch 62 below the left lever pivot 70.

[0110] Cable 134 is connected to terminals 94 of connection detection sensor 92 via a pair of connectors 134a. After extending rearward from connection detection sensor 92, cable 134 passes under left lever pivot 70 and is guided to left handle switch 62.

[0111] Cables 133 and 134, which are introduced into the left handlebar switch 62, are led out from the left handlebar switch 62 as wiring harness 131 and connected to an ECU (not shown).

[0112] Figure 11 This is a diagram illustrating the function when viewed from above along the axial direction. Figure 12 This is a diagram illustrating the function when viewed from below along the axial direction.

[0113] In the clutch lever support mechanism 63, the clutch lever 80 is capable of swinging about the swing shaft 112. The clutch lever 80 can swing between the engagement position P0 (shown by the solid line) and the disengagement position P1 (shown by the double-dotted line). When the clutch lever 80 swings, the first protrusion 85 of the clutch lever 80 moves on an imaginary circle C1 centered on the swing shaft 112. Additionally, the second protrusion 86 of the clutch lever 80 moves on an imaginary circle C2 centered on the swing shaft 112. Both imaginary circles C1 and C2 are concentric circles centered on the swing shaft 112. Therefore, the first protrusion 85 and the second protrusion 86 are located on concentric circles centered on the swing shaft 112. Similarly, the first opening 75 and the second opening 76, which allow the first protrusion 85 and the second protrusion 86 to enter and move, are located on concentric circles centered on the swing shaft 112.

[0114] In particular, in this embodiment, the first protrusion 85 and the second protrusion 86 are disposed on both sides, separated by the swing shaft 112. Similarly, the first opening 75 and the second opening 76 are disposed on both sides, separated by the swing shaft 112. More specifically, in this embodiment, the first protrusion 85 and the second protrusion 86 are disposed on both sides separated by the line L0 (the center of the swing shaft 112 and the front-rear center of the right end of the spacer 73c) connecting the swing shaft 112 and the spacer 73c. ​​Similarly, the first opening 75 and the second opening 76 are disposed on both sides separated by the line L0. Sensor mounting portions 77 and 78 are disposed on both sides separated by the line L0.

[0115] Here, with the clutch lever 80 in the engaged position P0, the inner cable of the clutch cable 132 is pulled by a force-applying component (not shown), and the contact surface 81a remains in contact with the left lever pivot 70. At this time, since the second protrusion 86 presses against the switch 95 of the connection detection sensor 92, the connection detection sensor 92 is activated, and this activation status is input to the ECU. Therefore, the ECU can detect that the clutch lever 80 has moved to the engaged position P0 and that the transmission is engaged. Additionally, at this time, the first protrusion 85 of the clutch lever 80 moves away from the switch 95 of the cut-off detection sensor 91, and the cut-off detection sensor 91 is deactivated.

[0116] When the clutch lever 80 is actuated and moves to the cut-off position P1, the clutch lever 80 rotates around the pivot shaft 112, and the cable engagement portion 83 moves away from the left lever pivot 70. Therefore, the inner cable of the clutch cable 132 is pulled by the clutch lever 80, and the transmission clutch is disengaged. At this time, the first protrusion 85 of the clutch lever 80 moves towards the cut-off detection sensor 91, pressing the switch 95 of the cut-off detection sensor 91. Therefore, the cut-off detection sensor 91 is activated, and this activation is input to the ECU. Thus, the ECU can detect that the clutch lever 80 has moved to the cut-off position P1 and the transmission is disengaged. Additionally, at this time, the second protrusion 86 of the clutch lever 80 moves away from the switch 95 of the position detection sensor 92, and the position detection sensor 92 is deactivated.

[0117] In this embodiment, the ECU is able to detect with high precision whether the clutch lever 80 is in the disengaged position P1 or the engaged position P0.

[0118] In this embodiment, the ECU performs idle stop processing based on the inputs from sensors 91 and 92. For example, when the transmission is in neutral, the ECU stops the power unit 12, which is the engine. Alternatively, when the transmission is in gear and the ECU detects that the clutch lever 80 has moved to the disengaged position P1, the ECU stops the power unit 12. Thus, in this embodiment, an appropriate idle stop function corresponding to the driving scenario can be provided.

[0119] As described above, according to this embodiment of the present invention, a saddle-type vehicle 10 is provided, comprising: a clutch lever 80; a swing shaft 112 supporting the clutch lever 80 to allow it to swing; a left lever pivot 70 on which the swing shaft 112 is disposed; and a cut-off detection sensor 91 and a connection detection sensor 92, which have switches 95 pressed by the clutch lever 80. In this saddle-type vehicle 10, the cut-off detection sensor 91 is fixed to the upper surface of the left lever pivot 70. 73a, The connection detection sensor 92 is fixed to the lower surface 73b of the left rod pivot 70. When viewed along the axial direction of the swing shaft 112, the switch 95 of the cut-off detection sensor 91 and the switch 95 of the connection detection sensor 92 are arranged in a concentric circle with the swing shaft 112. The switch 95 of the cut-off detection sensor 91 is pressed when the clutch lever 80 moves to the cut-off position P1, and the switch 95 of the connection detection sensor 92 is pressed when the clutch lever 80 moves to the connection position P0.

[0120] Based on this structure, a saddle-mounted vehicle 10 can be provided where, when viewed along the axial direction of the swing shaft 112, the switch 95 of the cut-off detection sensor 91 and the switch 95 of the connection detection sensor 92 can be arranged concentrically across the swing shaft 112. This allows for high-precision detection of the clutch lever 80 moving to the cut-off position P1 or the connection position P0 with a simple structure that minimizes the complexity of the arrangement of components such as sensors 91 and 92. Therefore, even in saddle-mounted vehicles 10 designed for small-displacement and low-cost LMC (Light Motor Cycle) motorcycles, an appropriate idle stop function suitable for the driving scenario can be easily installed.

[0121] In this embodiment, a first protrusion 85 is provided on the upper surface (one side in the swing axis direction) of the clutch lever 80. When the first protrusion 85 is moved to the cut-off position P1, it presses the switch 95 of the cut-off detection sensor 91. A second protrusion 86 is provided on the lower surface (the other side in the swing axis direction) of the clutch lever 80. When the second protrusion 86 is moved to the connection position P0, it presses the switch 95 of the connection detection sensor 92. When viewed along the axial direction of the swing axis 112, the first protrusion 85 and the second protrusion 86 are arranged in a concentric circle shape across the swing axis 112.

[0122] Based on this structure, by adding a simple construction to the clutch lever 80, the switch 95 of the cut-off detection sensor 91 and the switch 95 of the connection detection sensor 92 can be pressed with high precision. Therefore, even in models like the LMC, which require small displacement and low price, it is easy to install an appropriate idle stop function corresponding to the driving scenario.

[0123] In addition, in this embodiment, a first opening 75 is provided on the upper surface 73a of the left lever pivot 70, allowing the first protrusion 85 of the clutch lever 80 to enter, and a second opening 76 is provided on the lower surface 73b of the left lever pivot 70, allowing the second protrusion 86 of the clutch lever 80 to enter. When viewed along the axial direction of the swing shaft 112, the first opening 75 and the second opening 76 are arranged in a concentric circle across the swing shaft 112.

[0124] According to this structure, the first protrusion 85 can enter the first opening 75, and the second protrusion 86 can enter the second opening 76, thereby enabling the switch 95 of the sensor 91 that is not easy to form a cut-off detection and the switch 95 of the sensor 92 that is connected to the detection to protrude from the left rod pivot 70 when viewed along the axial direction of the swing axis 112.

[0125] In addition, in this embodiment, the rod cover 100 is tightly attached to the left rod pivot 70. When the vehicle body is viewed from above, the rod cover 100 overlaps with the cut detection sensor 91 and the connection detection sensor 92.

[0126] According to this structure, the switch 95 of sensors 91 and 92 can be easily protected from foreign objects, and sensors 91 and 92 can be easily protected from water such as rain.

[0127] In addition, in this embodiment, the cut detection sensor 91 and the connection detection sensor 92 have the same shape.

[0128] According to this structure, both the cut-off detection sensor 91 and the connection detection sensor 92 can be implemented using sensors of the same shape, thus allowing for the commonality of the configuration layout of sensors 91 and 92, as well as the connection components of sensors 91 and 92. Furthermore, the ability to implement both the cut-off detection sensor 91 and the connection detection sensor 92 using a common sensor easily reduces the variety of components required. Therefore, this structure helps to minimize cost increases.

[0129] [Other Implementation Methods]

[0130] The above-described embodiments are merely one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.

[0131] In the above embodiment, the saddle-mounted vehicle 10 was described as an example of an automatic two-wheeled vehicle equipped with a power unit 12 (having an internal combustion engine), but the power unit could also be an electric motor. That is, the saddle-mounted vehicle could also be an electric vehicle.

[0132] In the above embodiments, the saddle-riding vehicle 10 is described as an example of an automatic two-wheeled vehicle with front wheels 13 and rear wheels 15. However, the present invention is not limited to this. The present invention can be applied to three-wheeled saddle-riding vehicles with two front wheels or rear wheels, or saddle-riding vehicles with four or more wheels.

[0134] The above implementation supports the following structures.

[0135] (Structure 1) A saddle-type vehicle comprising: a clutch lever; a swing shaft supporting the clutch lever for swinging; a lever pivot at which the swing shaft is disposed; and a first sensor and a second sensor having switches pressable by the clutch lever, characterized in that the first sensor is fixed to one face of the lever pivot in the swing axis direction, and the second sensor is fixed to another face of the lever pivot in the swing axis direction, wherein, when viewed along the axial direction of the swing shaft, the switches of the first sensor and the second sensor are arranged concentrically across the swing shaft, the switch of the first sensor is pressed when the clutch lever is moved to a gripped position, and the switch of the second sensor is pressed when the clutch lever is moved to a non-griped position.

[0136] Based on this structure, a saddle-mounted vehicle can be provided where the switches of the first and second sensors are arranged concentrically across the swing shaft when viewed axially. This allows for high-precision detection of the clutch lever's movement to the engaged or disengaged position with a simple structure that minimizes the complexity of the sensor and other component layouts. Therefore, even in saddle-mounted vehicles with engines like the LMC that require small displacement and low price, an appropriate idle stop function suitable for the driving scenario can be easily installed.

[0137] (Structure 2) In the saddle-type vehicle of Structure 1, the first protrusion is provided on one side of the clutch lever in the swing axis direction, which is a switch for pressing the first sensor when the clutch lever is moved to the gripping position, and a second protrusion is provided on the other side of the clutch lever in the swing axis direction, which is a switch for pressing the second sensor when the clutch lever is moved to the non-grip position. When viewed along the axial direction of the swing axis, the first protrusion and the second protrusion are arranged in a concentric circle with the swing axis between them.

[0138] Based on this structure, by adding a simple mechanism to the clutch lever, the switches for the first and second sensors can be pressed with high precision. Therefore, even in models like the LMC, which require small displacement and low price, it is easy to install an appropriate idle stop function corresponding to the driving scenario.

[0139] (Structure 3) In the saddle-type vehicle of Structure 2, the first recess is provided on one side of the lever pivot in the swing axis direction, into which the first protrusion of the clutch lever can enter, and a second recess is provided on the other side of the lever pivot in the swing axis direction, into which the second protrusion of the clutch lever can enter, and when viewed along the axial direction of the swing axis, the first recess and the second recess are arranged in a concentric circle across the swing axis.

[0140] According to this structure, by enabling the first protrusion to enter the first recess and the second protrusion to enter the second recess, it is possible to make the switch that is not easy to form a first sensor or a second sensor protrude from the rod pivot when viewed along the axial direction of the swing axis.

[0141] (Structure 4) In any of the structures 1 to 3 of the saddle-type vehicle, the characteristic is that a rod cover is tightly fitted on the rod pivot, and when the vehicle body is viewed from above, the rod cover overlaps with the first sensor and the second sensor.

[0142] According to this structure, the switching part of the sensor can be easily protected from foreign objects, and the sensor can be easily protected from water such as rain.

[0143] (Structure 5) In any of the structures 1 to 4, the saddle-type vehicle is characterized in that the first sensor and the second sensor have the same shape.

[0144] Based on this structure, both the first and second sensors can be implemented using sensors of the same shape, thus enabling the generalization of sensor configuration layouts, sensor connection components, etc. Furthermore, the ability to implement both the first and second sensors using a common sensor easily reduces the variety of components required. Therefore, cost increases can be minimized.
