Description

The present invention relates to a stand device.

In recent years, as a saddle-mounted vehicle, a vehicle having an interlock mechanism for restricting traveling while the stand is upright is known (see, for example, Patent Documents 1-3). The interlock mechanism of Patent Documents 1 and 2 detects the swing angle of the stand by a rotary type stand switch in order to distinguish between the standing state in which the stand is lowered and the retracted state in which the stand is flipped up. However, since the rotary type stand switch extends radially outward from the swing center of the stand, there is a problem that the stand switch widely occupies the periphery of the swing center of the stand.

In this regard, since the interlock mechanism of Patent Document 3 uses a direct hit type stand switch having a small installation area, a sufficient space is secured even if the stand switch is mounted around the swing center of the stand. An operator protrudes from the direct hit type stand switch, and the stand switch can be turned ON or OFF depending on the amount of operation on the operator. Normally, when the stand is flipped up, the operator of the stand switch is pushed by the stand, so that the stand switch is turned on and the operating circuit of the power unit is made conductive.

However, in the stand switch described in Patent Document 3, the operator of the stand switch may be excessively pushed by the swing of the stand. In addition, the operation of the stand switch may be adversely affected by the vibration (fluttering) of the stand.

The present invention has been made in view of this point, and provides a stand device capable of preventing excessive pushing of the stand switch into an operator and suppressing an adverse effect of stand vibration on the operation of the stand switch. The purpose.

The stand device of one aspect of the present invention includes a stand that swings between an upright position that makes the vehicle body stand on its own and a storage position that releases the independence, and a stand switch that detects the swing of the stand to the upright position or the storage position. The stand device is provided with an operator for detecting the swing of the stand according to the amount of operation, and the stand is swung around the swing center of the stand. As a result, a sliding contact surface that is in sliding contact with the operator is formed, and the amount of operation with respect to the operator changes according to the swing angle of the stand due to the undulations of the sliding contact surface. Solves the above problem by giving the maximum amount of operation to the operator.

According to the stand device of one aspect of the present invention, the operator of the stand switch is operated by the sliding contact surface of the stand by swinging the stand toward the standing position or the retracted position. At this time, since the amount of operation of the operator of the stand switch is maximized during the swinging operation of the stand, even if the stand is shaken beyond the swing range, the operator is moved from the maximum amount of operation due to the sliding contact surface. Is not over-operated. Further, since the operation amount of the operator changes depending on the undulations of the sliding contact surface, even if vibration (fluttering) occurs in the stand, the operation amount of the operator is small and the operation of the stand switch is not adversely affected.

In the stand device of one aspect of the present invention, the stand swings between the standing position for making the vehicle body stand on its own and the storage position for releasing the self-support, and the stand switch detects the swing of the stand to the standing position or the storage position. There is. The stand switch is provided with an operator that detects the swing of the stand according to the amount of operation, and a sliding contact surface that slides into contact with the operator as the stand swings is formed around the swing center of the stand. ing. The amount of operation on the operator changes according to the swing angle of the stand due to the undulations of the sliding contact surface, and the amount of operation on the operator reaches the maximum amount during the swing operation of the stand. Therefore, even if the stand is swung beyond the swing range, the operator is not operated excessively by the sliding contact surface more than the maximum operating amount. In addition, the amount of operation of the operator changes depending on the undulations of the sliding contact surface. Therefore, even if the stand vibrates, the amount of operation on the operator is small and the operation of the stand switch is not adversely affected.

Hereinafter, this embodiment will be described in detail with reference to the accompanying drawings. In this embodiment, the saddle-type vehicle is a scooter-type saddle-type vehicle, but the saddle-type vehicle may be another electric or hybrid-type saddle-type vehicle. Further, in the following figures, the arrow FR indicates the front of the vehicle, the arrow RE indicates the rear of the vehicle, the arrow L indicates the left side of the vehicle, and the arrow R indicates the right side of the vehicle.

FIG. 3 is a diagram showing an example of the swinging operation of the center stand of the comparative example.

As shown in FIG. 1, the scooter type saddle-mounted vehicle 1 is configured by attaching various covers as a vehicle body exterior to an underbone type vehicle body frame 10 (see FIG. 2). A front frame cover 21 is provided on the front side of the vehicle, and a leg shield 22 for protecting the undercarriage of the occupant is provided on the rear side of the front frame cover 21. A step board 23 extends from the lower end of the leg shield 22 toward the rear, and a rear frame cover 24 is provided behind the step board 23. The leg shield 22 and the step board 23 form a footrest space for the occupant in front of the rider seat 41.

A handle 32 is provided on the upper side of the front frame cover 21, and the front wheels 34 are rotatably supported on the lower side of the front frame cover 21 via a pair of front forks 33. A rider seat 41 and a pillion seat 42 are provided on the upper side of the rear frame cover 24, and a swing arm 43 (see FIG. 2) covered with a swing arm cover 47 is provided on the lower side of the rear frame cover 24. A rear wheel 44 is rotatably supported at the rear portion of the swing arm 43, and the rear portion of the swing arm 43 is connected to a vehicle body frame 10 (support frame 15) via a suspension 45.

As shown in FIG. 2, a head pipe 11 into which the steering shaft 17 is inserted is provided on the front side portion of the vehicle body frame 10. The front frame 12 extends downward from the head pipe 11, and a pair of lower frames 13 extend rearward from the lower part of the front frame 12. A pair of rear frames 14 rise diagonally rearward from a substantially intermediate portion of the pair of lower frames 13, and a pair of support frames 15 rise diagonally rearward from the rear portion of the pair of lower frames 13. The rear portions of the pair of support frames 15 are connected to the rear portions of the pair of rear frames 14 from below.

Inside the pair of rear frames 14 and the pair of support frames 15, installation spaces for various electric components are formed. The battery unit 51 is installed on the upper side of the installation space, and the motor 52 is installed on the lower side of the installation space. In front of the motor 52, an inverter 53 is installed inside a pair of lower frames 13. The battery unit 51, the inverter 53, and the motor 52 are connected via a power transmission cable. DC power is stored in the battery unit 51 for the motor 52, and the DC power of the battery unit 51 is converted into AC power by the inverter 53 and supplied to the motor 52.

The pair of rear frames 14 and the pair of support frames 15 are connected in the front-rear direction via a pair of pivot brackets 16, respectively. A swing arm 43 is swingably connected to the pair of pivot brackets 16 in the vertical direction, and a swing arm cover 47 (see FIG. 1) is attached to the swing arm 43 as described above. The swing arm cover 47 covers the sprocket 55 and the chain 46 of the motor 52. Electric power is supplied from the battery unit 51 to the motor 52 via the inverter 53, and the driving force is output from the motor 52 to the rear wheels 44 via the sprocket 55 and the chain 46.

At the lower part of the saddle-mounted vehicle 1, a stand device 60 for making the vehicle body independent is provided. The center stand (stand) 61 of the stand device 60 is between the standing position P _{a (see FIG. 9 (A)) in contact with the road surface and the storage position P b} (see FIG. 9 (D)) on the lower side of the swing arm cover 47. Is rocked by. The vehicle body becomes self-supporting when the center stand 61 is lowered from the storage position P _b to the standing position P _a , and the vehicle body becomes self-supporting when the center stand 61 is flipped up _{from the standing position P a} to the storage position P _b. .. Further, the stand device 60 is provided with an interlock mechanism that regulates the traveling of the saddle-mounted vehicle 1 with the center stand 61 upright.

As shown in the comparative example of FIG. 3A, a general interlock mechanism is provided with a stand switch 95 for detecting the swing of the stand 91 to the _{storage position P b.} The operator 96 protrudes from the stand switch 95, and when the operator 96 is pushed by the stand 91, the stand switch 95 is turned on and the operating circuit of the power unit becomes conductive. An operation surface 97 for pushing the operator 96 is formed on the stand 91. Since the operation surface 97 of the stand 91 is separated from the swing center O of the stand 91, the amount of operation of the operator 96 by the operation surface 97 increases as the amount of swing of the stand 91 increases.

Therefore, as shown in FIG. 3B, when the stand 91 comes into contact with the obstacle 100 or the like during traveling, the stand 91 is _{pushed up beyond the storage position P b,} and the operator 96 is excessively pushed by the stand 91. It may be pushed in. Further, as shown in FIG. 3C, if the stand 91 is positioned at the storage position P _b and the stand 91 vibrates during traveling, the stand 91 may be separated from the operator 96 and the stand switch 95 may erroneously detect it. is there. As described above, the interlock mechanism of the stand device 90 is required to have a structure with higher safety in consideration of the fact that the stand 91 swings against the intention of the passenger.

Therefore, the interlock mechanism of the stand device 60 of this embodiment is realized by a cam member 77 provided around the swing center O of the center stand 61 and a stand switch 81 operated by the cam member 77. (See FIG. 4). As a result, the operator 83 of the stand switch 81 is operated by the cam member 77 as the center stand 61 swings. The operation amount of the operator 83 does not depend on the swing amount of the center stand 61, and the operation amount of the operator 83 is determined by the cam profile of the cam member 77. Therefore, the above-mentioned problems caused by the swing of the center stand 61 do not occur.

Hereinafter, the stand device will be described with reference to FIGS. 4 to 7. FIG. 4 is a left side view of the stand device. FIG. 5 is a right side view of the stand device. FIG. 6 is a perspective view of the stand device as viewed from below. FIG. 7 is an enlarged view of the periphery of the cam member of the stand device. In FIG. 7, the state in which the stand is positioned in the upright position is shown by a solid line, and the state in which the stand is positioned in the retracted position is shown by a chain double-dashed line.

As shown in FIGS. 4 to 6, the center stand 61 of the stand device 60 is attached to the rear end of the pair of lower frames 13 (body frame 10) via a plate-shaped connecting bracket 19. A U-shaped plate-shaped base bracket 63 is provided on the base end side of the pair of legs 62 of the center stand 61. The connecting bracket 19 is positioned inside the U-shaped plate of the base bracket 63, and the base bracket 63 is pivotally supported by the connecting bracket 19 via a pivot bolt 64. Accordingly, the center stand 61 to the supporting point pivot bolt 64 is swung between the upright position P _a and the storage position P _{b (see} FIG. 9 (D)).

A curved plate-shaped ground contact portion 65 in contact with the ground is provided on the tip end side of the pair of leg portions 62. On the left side of the leg portion 62, the operation bar 66 for swinging to the standing position P _a center stand 61 from the storage position P _b is provided. When the center stand 61 is positioned at the storage position P _b , the stepping portion 67 at the tip of the operation bar 66 is directed upward. By stepping force of the rider is applied to踏付portion 67, the center stand 61 is swung toward the storage position P _b in the standing position P _a. The left leg 62 and the operation bar 66 are connected by a reinforcing member 68 extending diagonally. The reinforcing material 68 ensures the strength and rigidity of the operation bar 66.

The pair of legs 62 are connected by a pair of bridges 71 and 72 extending in the vehicle width direction, and the pair of bridges 71 and 72 are provided with a plate-shaped guard material 73. As a result, the pair of legs 62 are strongly connected in the vehicle width direction, and the pair of legs 62 are integrally swung around the pivot bolt 64 as a fulcrum. The intermediate position between the right connecting bracket 19 and the leg 62 is connected via a tension spring 74. When the center stand 61 is pushed down beyond the change point, the center stand 61 by the tension spring 74 is pulled in the standing position P _a. When the center stand 61 is flipped up beyond the thought point, the pull spring 74 pulls the center stand 61 into the storage position P _b .

Further, the pivot bracket 16 on the left side is provided with a stopper 75 that restricts the _{center stand 61 to the storage position P b.} The stopper 75 extends diagonally downward toward the rear, and a rubber cushioning material 76 is provided at the tip of the stopper 75. Below the stopper 75, a stand switch 81 for detecting the swing of the center stand 61 to the _{storage position P b is provided.} The stand switch 81 is a so-called direct hit type switch, and detects the center stand 61 by pushing the operator 83 into the switch case 82. The tip of the operator 83 is positioned near the swing center O of the base bracket 63 (center stand 61) on the left side.

The base bracket 63 on the left side is provided with a plate-shaped cam member 77 for operating the operator 83 of the stand switch 81. The cam member 77 is formed in a side view arc shape so as to partially surround the swing center O of the center stand 61. As the center stand 61 swings, the cam member 77 comes into contact with the operator 83, and the cam member 77 operates the operator 83 in the pushing direction. The operation amount of the operator 83 is changed by the cam profile of the cam member 77, by swinging of the center stand 61 to the storage position P _b in accordance with the operation amount of the operator 83 is detected, the stand switch 81 is ON The operating circuit of the power unit becomes conductive.

As shown in FIG. 7, the cam member 77 is formed with a sliding contact surface 78 that is in sliding contact with the operator 83 as the center stand 61 swings. The distance from the swing center O of the center stand 61 to the sliding contact surface 78 is formed so as to differ depending on the rotation direction of the cam member 77. The distance from the swing center O to the sliding contact surface 78 increases while moving from the one end position 85 to the intermediate position 86 of the sliding contact surface 78, and sliding from the swing center O while moving from the intermediate position 86 to the other end position 87. The distance to the contact surface 78 is kept constant. The operator 83 is operated in the pushing direction by the change in the distance from the swing center O to the sliding contact surface 78, that is, the undulations of the sliding contact surface 78.

More specifically, the distance from the swing center O of the center stand 61 to the one end position 85 of the sliding contact surface 78 is r ₁ [mm]. The distance r ₁ [mm] is the distance at which the sliding contact surface 78 starts to come into contact with the tip of the operator 83. The distance from the swing center O of the center stand 61 to the intermediate position 86 of the sliding contact surface 78 is r ₂ [mm]. The distance r ₂ [mm] is the distance at which the operator 83 is pushed to the maximum manipulated variable A _max (see FIG. 8). The distance from the swing center O to the sliding contact surface 78 does not change at _{r 2} [mm] between the intermediate position 86 and the other end position 87 of the sliding contact surface 78. Therefore, the operator 83 is maintained in a state of being pushed to the _{maximum operation amount A max.}

The maximum operation amount A _{max of the operator 83 is set to be larger than the detection operation amount A on} (see FIG. 8) in which the stand switch 81 detects the center stand 61. Further, the sliding contact surface 78 is not in contact with the operating element 83 is in a state in which the center stand 61 is positioned at the standing position P _a, of the rocking motion of the center stand 61 toward the storage position P _b from the standing position P _a On the way, the intermediate position 86 of the sliding contact surface 78 comes into contact with the operator 83. The operating amount of the operator 83 changes according to the swing angle of the center stand 61 due to the undulations of the sliding contact surface 78, and the maximum operating amount A _max is given to the operator 83 by the sliding contact surface 78 during the swing. The swing of the center stand 61 to the storage position P _{b is detected by the stand switch 81.}

The detection operation of the stand switch will be described with reference to FIGS. 8 to 10. FIG. 8 is a graph showing the relationship between the swing angle of the center stand and the operation amount of the operator. 9 and 10 are views showing an example of the swinging operation of the center stand. FIG. 9A shows a state in which the center stand is positioned in the upright position, and FIG. 9B shows a state in which the center stand is positioned at the thought point. FIG. 9C shows a state in which the center stand is positioned at the detection position, and FIG. 9C shows a state in which the center stand is positioned at the retracted position. FIG. 10A shows a state in which the center stand oscillates excessively, and FIG. 10B shows a state in which the center stand oscillates in the retracted position.

As shown in FIG. 8 and FIG. 9 (A), the in the state where the center stand 61 is positioned at the standing position P _a, the vehicle is free-standing in a state in which the rear wheel 44 (see FIG. 4) is lifted from the ground by the center stand 61 doing. At this time, the center stand 61 is _{stopped at the swing angle θ 0} , and the sliding contact surface 78 of the cam member 77 is not in contact with the tip of the operator 83. Since the amount of operation of the actuator 83 by the sliding contact surface 78 is 0, the stand switch 81 is turned off. From a state where the center stand 61 is positioned at the standing position P _a, is splashed is center stand 61 by the passenger, the center stand 61 starts to oscillate toward the retracted position P _b.

As shown in FIG. 8 and FIG. 9 (B), the legs of the center in the state where the stand 61 is swung to the thought position P _c from standing position P _a, a tension spring 74 (see FIG. 5) in the pulling direction and the center stand 61 The extending directions of the portions 62 are the same. At this time, the tensile force of the tensile spring 74 does not act in the swing direction of the center stand 61. Further, the center stand 61 swings _{up to a swing angle θ 1} , and one end position 85 of the sliding contact surface 78 starts sliding contact with the tip of the operator 83. Since the operator 83 is not pushed by the sliding contact surface 78 from the standing position P _a to the thought position P _{c, the} amount of operation of the operator 83 by the sliding contact surface 78 does not change from 0.

As shown in FIGS. 8 and 9 (C), when the center stand 61 _{swings beyond the thought position P c} to the detection position P _d , the center stand 61 separates from the ground and the rear wheels 44 (see FIG. 1) move. Ground on the ground. At this time, the tensile force of the tensile spring 74 (see FIG. 5) acts in the swinging direction of the center stand 61, and the pulling force causes the center stand 61 to swing. The center stand 61 swings _{up to a swing angle θ 2,} and the intermediate position 86 of the sliding contact surface 78 is positioned at the tip of the operator 83. Since the operator 83 is operated by the sliding contact surface 78 up to the maximum manipulated variable A _max , the stand switch 81 is switched from OFF to ON, and the operating circuit of the power unit becomes conductive.

As shown in FIGS. 8 and 9 (D), when the center stand 61 _{swings beyond the detection position P d} to the storage position P _b , the rear wheel 44 touches the ground and the vehicle body is completely released from independence. To. At this time, the center stand 61 swings _{up to the swing angle θ 3,} and the other end position 87 closer to the intermediate position 86 of the sliding contact surface 78 is positioned at the tip of the operator 83. Since the distance from the swing center O to the sliding contact surface 78 does not change between the intermediate position 86 and the other end position 87 of the sliding contact surface 78, the amount of operation of the operator 83 by the sliding contact surface 78 is the maximum amount of operation A. It has not changed from _max. Therefore, the stand switch 81 is held in the ON state.

Further, as shown in FIGS. 8 and 10A, when the center stand 61 _{swings beyond the storage position P b} , the cushioning material 76 of the stopper 75 is crushed by the center stand 61. At this time, the center stand 61 swings _{up to the swing angle θ 4,} and the other end side of the sliding contact surface 78 is positioned at the tip of the operator 83. As described above, since the distance from the swing center O to the sliding contact surface 78 does not change between the intermediate position 86 and the other end position 87 of the sliding contact surface 78 (see FIG. 7), the operation by the sliding contact surface 78 is performed. The manipulated variable of the child 83 is never manipulated beyond the _{maximum manipulated variable A max.} Therefore, the operator 83 of the stand switch 81 is not excessively pushed by the center stand 61.

Further, as shown in FIGS. 8 and 10B, when the center stand 61 _{vibrates at the storage position P b} , the center stand 61 swings with reference to the _{storage position P b.} At this time, the center stand 61 swings _{between the swing angle θ 3} and the swing angle θ ₅ , and the vicinity of the intermediate position 86 of the sliding contact surface 78 is in sliding contact with the tip of the sliding contact surface 78. Between the swing angle θ ₃ and the swing angle θ ₅ , the operation amount of the operator 83 by the sliding contact surface 78 is _{equal to or more than the detection operation amount A on} and is equal to or less than the maximum operation amount A _max. Therefore, even if the center stand 61 vibrates, the stand switch 81 is maintained in the ON state.

_{Further, in this embodiment, after the maximum operation amount A max} is given to the operator 83 during the swinging operation of the center stand 61, the operation amount of the detection operation amount A _on or more is maintained by the operator 83. The center stand 61 is swung up to the _{storage position P b.} This is different from the configuration in which the operation amount of the detection operation amount A _on or more is given to the operator 83 when the center stand 61 _{swings to the storage position P b.} Therefore, even if an error in the undulations of the sliding contact surface 78 occurs, the sliding contact surface 78 gives the operator 83 _{an operation amount equal to or greater than the detection operation amount A on} , and the stand switch 81 gives the storage position P of the center stand 61. _{The swing to b} is reliably detected.

As described above, according to this embodiment, since the center stand 61 is swung toward the storage position P _b from the standing position P _a, operator 83 of the stand switch 81 by the sliding surface 78 of the center stand 61 is operated Will be done. At this time, since the amount of operation of the operator 83 of the stand switch 81 is maximized during the swinging operation of the center stand 61, even if the center stand 61 is swung beyond the swing range, the sliding contact surface 78 causes the center stand 61 to swing. The operator 83 is not operated more than the _{maximum manipulated variable A max.} Further, since the operation amount of the operator 83 changes depending on the undulations of the sliding contact surface 78, even if the center stand 61 vibrates (flutters), the operation amount of the operator 83 is small and the operation of the stand switch 81 is adversely affected. Never.

In this embodiment, the operating amount of the operator is kept constant after the maximum operating amount is given to the operator due to the undulations of the sliding contact surface, but the present invention is not limited to this configuration. After the maximum manipulated variable is given to the operator by the undulations of the sliding contact surface, the operator may be given an manipulated variable equal to or less than the maximum manipulated variable and greater than or equal to the detected manipulated variable. The undulations of the sliding contact surface may reduce the amount of operation on the operator after the maximum amount of operation has been given to the operator.

For example, as shown by the alternate long and short dash line in FIG. 8, while the center stand swings from the swing angle θ _{1 to the swing angle θ 2} , the operating amount of the operator increases from 0 to the maximum due to the undulations of the sliding contact surface. The amount is increased to _{A max.} When the center stand swings _{beyond the swing angle θ 2} , the operating amount of the operator gradually decreases from the _{maximum operating amount A max due to the undulations of the sliding contact surface.} With this configuration, even if the center stand swings _{beyond the swing range from the swing angle θ 0} to the swing angle θ ₃ and swings up to the swing angle θ ₄ , the amount of operation of the operator is reduced, so that the center The stand ensures that the controls are not over-operated. Further, since _{the vicinity of the swing angle θ 3} is the detection operation amount A _on or more, the stand switch is maintained in the detection state even if the stand swings at the retracted position.

Further, in this embodiment, the stand switch is used to detect the swing of the center stand to the retracted position, but the configuration is not limited to this. The stand switch may detect the swing of the center stand to the upright position. Even in such a case, when the center stand swings beyond the standing position, the center stand prevents the operator from being excessively operated. Further, even if the center stand vibrates in the upright position for some reason, the stand switch is maintained in the detected state.

Further, in the present embodiment, the cam member is provided on the center stand, but the configuration is not limited to this. The center stand may be formed with a sliding contact surface that is in sliding contact with the operator as the stand swings around the center of swing of the stand. For example, a sliding contact surface that is in sliding contact with the operator of the stand switch may be formed on the outer surface of the base bracket of the center stand.

Further, in the present embodiment, the stand switch detects the swing of the center stand by pushing the operator into the switch case by the sliding contact surface, but the configuration is not limited to this. The stand switch may detect the swing of the center stand by pushing the operator out of the switch case by the sliding contact surface.

Further, in this embodiment, the center stand is illustrated as the stand, but the stand may be a side stand, for example, as long as the saddle-mounted vehicle can stand on its own.

Further, in the present embodiment, the configuration in which the stand device is applied to the scooter type saddle-mounted vehicle has been described, but the configuration is not limited to this configuration. The stand device can be applied to other saddle-mounted vehicles. For example, the stand device can also be applied to an engine-powered saddle-mounted vehicle. Further, the saddle-mounted vehicle is not limited to a motorcycle, and may be, for example, a buggy-type motorcycle, a lawn mower, or the like.

As described above, the stand device (60) of the present embodiment includes a stand (center stand 61) that swings between _{an upright position (P a} ) for making the vehicle body stand on its own and a storage position (P _{b) for releasing the independence.} A stand device including a stand switch (81) for detecting the swing of the stand to an upright position or a retracted position, and the stand switch has an operator (83) for detecting the swing of the stand according to the amount of operation. ) Is provided, and a sliding contact surface (78) that slides into contact with the operator is formed around the swing center (O) of the stand, and the stand swings due to the undulations of the sliding contact surface. The amount of operation with respect to the operator changes according to the angle, and the sliding contact surface gives the operator the maximum amount of operation (A _max ) during swinging. According to this configuration, the stand is swung toward the upright position or the retracted position, so that the operator of the stand switch is operated by the sliding contact surface of the stand. At this time, since the operation amount of the operator of the stand switch is maximized during the swinging operation of the stand, even if the stand is shaken beyond the swinging range, the operator is moved from the maximum operating amount due to the sliding contact surface. Is not over-operated. Further, since the operation amount of the operator changes depending on the undulations of the sliding contact surface, even if vibration (fluttering) occurs in the stand, the operation amount of the operator is small and the operation of the stand switch is not adversely affected.

In the stand device of this embodiment, the operator _{detects the stand with a detection operation amount (A on} ) smaller than the maximum operation amount, and after the undulations of the sliding contact surface give the operator the maximum operation amount, Give the operator an operation amount that is less than or equal to the maximum operation amount and greater than or equal to the detection operation amount. According to this configuration, the maximum operating amount is given to the operator during the swinging operation of the stand, and the stand switch is turned on. In the latter half of the swinging operation of the stand, the operator is given an operation amount equal to or less than the maximum operation amount and more than the detection operation amount, and the stand switch is maintained in the ON state. Therefore, even if the stand vibrates within a range in which the operation amount of the operator is equal to or less than the maximum operation amount and equal to or more than the detection operation amount, the stand switch can be maintained in the ON state. Further, even if the stand is swung beyond the swing range, the operator is operated within the range of the maximum operation amount or less and the detection operation amount or more, so that the operator is not excessively operated by the stand.

In the stand device of this embodiment, the undulations of the sliding contact surface reduce the amount of operation with respect to the operator after the maximum amount of operation is given to the operator. According to this configuration, even if the stand is swung beyond the swing range, the amount of operation with respect to the operator is reduced, so that the stand prevents the operator from being excessively operated.

In the stand device of this embodiment, a cam member (77) is provided around the swing center of the stand, a sliding contact surface is formed on the cam member, and the cam member is from the swing center of the stand. It is formed so that the distance to the sliding contact surface differs in the rotation direction. According to this configuration, the sliding contact surface of the cam member comes into contact with the operator of the stand switch, and the amount of operation with respect to the operator is adjusted according to the distance from the swing center of the stand to the operator. Therefore, the cam member that rotates integrally with the stand can prevent excessive pushing of the stand switch into the operator, and suppress the adverse effect of the vibration of the stand on the operation of the stand switch.

Although this embodiment has been described, as another embodiment, the above embodiment and the modified example may be combined in whole or in part.

Further, the technique of the present invention is not limited to the above-described embodiment, and may be variously modified, replaced, or modified without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in another way by the advancement of the technology or another technology derived from it, it may be carried out by using that method. Therefore, the claims cover all embodiments that may be included within the scope of the technical idea.
