[0027] The embodiment of the present disclosure will be described with reference to the accompanying drawings. In addition, in each figure, the same reference numerals are given to the same or corresponding parts, and the repeated description of the parts is appropriately simplified or omitted.

[0028] Implementation method 1.

[0029] Figure 1 This is a diagram showing an overview of an elevator apparatus to which the position adjustment aid according to the first embodiment is applied. Figure 2 This is a side view of the hoisting machine to which the position adjustment tool according to the first embodiment is applied.

[0030] exist Figure 1 3 shows an elevator device 1. A hoistway 2 passes through each floor of a building 3. A machine room 4 is arranged just above the hoistway 2.

[0031] The hoisting machine 5 is installed in the machine room 4. The hoisting machine 5 is a so-called PM hoisting machine using a permanent magnet motor. The hoisting machine 5 includes two brakes 6.

[0032] The main rope 7 is wound around the sheave 5a of the traction machine 5. The car 8 is suspended on one side of the main rope 7 inside the hoistway 2. The counterweight 9 is suspended on the other side of the main rope 7 inside the hoistway 2. The control device 10 is installed in the machine room 4. The control device 10 is electrically connected to the traction machine 5 and the two brakes 6. The control device 10 can control the elevator device 1 as a whole.

[0033] For example, the control device 10 rotates the sheave 5a of the hoisting machine 5. The main rope 7 moves following the rotation of the sheave 5a of the hoisting machine 5. The car 8 and the counterweight 9 rise and fall in opposite directions to each other following the movement of the main rope 7. The control device 10 stops the sheave 5a of the hoisting machine 5 by operating the two brakes 6.

[0034] like Figure 2As shown, a disc brake is applied to the hoisting machine 5. Specifically, the hoisting machine 5 has a brake disc 5b. The brake disc 5b is mechanically connected to the sheave 5a. The brake disc 5b rotates synchronously with the sheave 5a. Two brakes 6 are installed at positions symmetrical in the left-right direction with respect to the rotating shaft of the hoisting machine 5. The two brakes 6 can apply braking force to the brake disc 5b respectively.

[0035] The hoisting machine 5 is provided with two brake switches 11. The two brake switches 11 are a brake switch 11a and a brake switch 11b. The brake switch 11a and the brake switch 11b have the same structure, but are provided at different positions. Hereinafter, the brake switches 11a and 11b are also representatively referred to as brake switches 11. The brake switch 11a is provided on one of the two brakes 6 by means of a mounting substrate 12a and a fastener 13a. The brake switch 11b is provided on the other of the two brakes 6 by means of a mounting substrate 12b and a fastener 13b. The mounting substrates 12a and 12b are respectively mounted on the outer surface 6s of the corresponding brake 6. That is, the brake switches 11a and 11b are respectively mounted on the side opposite to the sheave 5a and the brake disc 5b with respect to the outer surface 6s.

[0036] The brake switch 11a and the brake switch 11b are installed symmetrically with respect to the rotation axis of the brake disc 5b. Specifically, the mounting substrate 12a is located on the opposite side of the brake switch 11a. The mounting substrate 12b is located on the opposite side of the brake switch 11b.

[0037] Next, use Figure 3 The brake 6 will be described.

[0038] Figure 3 Schematic diagram of the brake of the position adjustment aid using the first embodiment. Figure 3 In FIG. 1 , the brake switch 11 a is shown as the brake switch 11 , and the mounting substrate 12 a is omitted from the illustration.

[0039] Figure 3 The brake 6 is shown in a state where no braking force is applied, that is, in an OFF state. The brake 6 includes a base 6a, an armature 6b, a pad 6c, a spring 6d, a sucker 6e, a transmission pin 6f, an amplifying plate 6g, and a plate fixing member 6h.

[0040] The base 6a constitutes the outer profile of the brake 6. A brake switch 11 is installed on the outer surface 6s of the base 6a. The armature 6b can move freely in the direction of the rotation axis of the brake disc 5b. The pad 6c is fixed to the armature 6b opposite to the brake disc 5b. The spring 6d is arranged between the base 6a and the armature 6b in a compressed state. The spring 6d applies a restoring force to the armature 6b in the direction of the brake disc 5b. For example, the attractor 6e includes an electromagnet. When current flows through the attractor 6e, the attractor 6e applies an attractive force to the armature 6b in the direction away from the brake disc 5b. In addition, the same mechanism such as the pad 6c can also be arranged on the opposite side of the brake disc 5b. In this case, the two pads 6c can clamp the brake disc 5b.

[0041] For example, the transmission pin 6f is formed in a rod shape. The end of one side of the transmission pin 6f is fixed to the armature 6b. The transmission pin 6f passes through the hole inside the base 6a. The end of the other side of the transmission pin 6f can protrude from the outer surface 6s. The amplifier plate 6g is a leaf spring. The amplifier plate 6g can be elastically deformed in the length direction. The amplifier plate 6g is arranged on the outer surface 6s at a position blocking the hole inside the base 6a. For example, the plate fixing member 6h is a bolt. The plate fixing member 6h fixes one end of the amplifier plate 6g in the length direction to the base 6a. In this state, the amplifier plate 6g has a restoring force toward the outer surface 6s. The plate fixing member 6h protrudes from the outer surface 6s together with the amplifier plate 6g. In addition, the plate fixing member 6h can also be regarded as a part of the structure of the amplifier plate 6g.

[0042] The brake switch 11 is mounted at a position facing the amplifier plate 6 g . The brake switch 11 includes a housing 14 , a signal line 15 , and a contact body 16 .

[0043] The housing 14 forms the outer shell of the brake switch 11. For example, a switch mechanism such as an electronic circuit is housed inside the housing 14. The signal line 15 includes a wire. The signal line 15 transmits the electrical signal generated by the switch mechanism to the Figure 3 The control device 10 is not shown in the figure. The contact body 16 is a button. The contact body 16 is supported by the housing 14 as an outer shell. The contact body 16 protrudes from the housing 14. The switch mechanism becomes a signal state corresponding to whether the button is operated, that is, whether the contact body 16 is pressed. For example, as one of the signal states, the switch mechanism sends an electrical signal only when the contact body 16 is pressed.

[0044] Although not shown, when the operating state of the brake 6 is the open state, the attractor 6e does not apply attraction to the armature 6b. The armature 6b is pressed in the direction of the restoring force of the spring 6d at the position where the pad 6c contacts the brake disc 5b. The pad 6c applies friction force to the brake disc 5b as a braking force. The end of the other side of the transmission pin 6f exists on the side closer to the inside of the base 6a than the outer surface 6s. In this case, the end of the unfixed side of the amplifier plate 6g exists at a position that does not float from the outer surface 6s. The end of the unfixed side of the amplifier plate 6g does not contact the contact body 16. The brake switch 11 becomes a signal state indicating that the contact body 16 is not pressed. In addition, in the open state, the amplifier plate 6g can also contact the contact body 16 to the extent that it is determined that the contact body 16 is not pressed.

[0045] like Figure 3 As shown, when the operating state of the brake 6 is the closed state, the attractor 6e applies an attractive force to the armature 6b. The armature 6b is pressed against the base 6a by the combined force of the attractive force and the restoring force of the spring 6d. In this case, the pad 6c does not contact the brake disc 5b. The end of the other side of the transmission pin 6f protrudes to the outside of the base 6a from the outer surface 6s. The end of the other side of the transmission pin 6f presses the central part of the amplifying plate 6g in the longitudinal direction toward the brake switch 11 side. The amplifying plate 6g is bent with the plate fixing member 6h as a base point by being pressed by the transmission pin 6f. The end of the amplifying plate 6g on the opposite side of the plate fixing member 6h in the longitudinal direction, that is, the operating part 6i, presses the contact body 16. The brake switch 11 becomes a signal state indicating that the contact body 16 is pressed. Here, the distance moved by the operating part 6i is greater than the amount of protrusion of the transmission pin 6f from the outer surface 6s. That is, the amplifying plate 6g plays a role of amplifying and transmitting the protrusion of the transmission pin 6f from the outer surface 6s.

[0046] Next, use Figure 4 The installation position of the brake switch 11 will be described.

[0047] Figure 4 1 is a side view of a brake switch of the position adjustment aid according to Embodiment 1. Figure 4 In the figure, the transmission pin 6f is omitted.

[0048] exist Figure 4 6g is shown in the figure when the brake 6 is in the open state. The housing 14 of the brake switch 11 is fixed at the mounting position. The mounting position is the distance at which the operating point of the contact body 16 satisfies the condition. Therefore, the brake switch 11 can detect the operating state of the brake 6 when it is in the mounting position.

[0049] When the brake switch 11 is in the mounted position, the length from the end of the plate fixing member 6h on the opposite side of the amplifying plate 6g to the contact body 16 in the longitudinal direction of the amplifying plate 6g is L1. In addition, the length from the end of the plate fixing member 6h on the opposite side of the amplifying plate 6g to the end of the operating portion 6i is L2.

[0050] In addition, the installation position is a position where the distance between the contact body 16 and the amplifying plate 6g in the open state is away from the prescribed action distance. For example, when the brake switch 11 is in the installation position, even if an object having the first thickness is sandwiched between the operating portion 6i and the contact body 16, it is not determined that the contact body 16 is pressed. When an object having the second thickness is sandwiched between the operating portion 6i and the contact body 16 in the open state, it is determined that the contact body 16 is pressed. When these determinations are achieved, the conditions of the action point are satisfied.

[0051] Specifically, the operating distance equal to the first thickness is 0.85 mm. The second thickness is 1.20 mm. In this case, when the contact body 16 moves more than 0.35 mm, it is determined that the contact body 16 is pressed. Thus, the accuracy required for the installation position of the brake switch 11 is very high.

[0052] When the brake switch 11 is in the installation position, the distance between the housing 14 and the outer surface 6s of the base 6a is separated by a predetermined installation distance L3. The installation distance L3 varies depending on the type of the brake 6, that is, the type of the traction machine 5. For example, the installation distance L3 is 8.0 mm. In the position adjustment method of this embodiment, the installation distance L3 is used.

[0053] Next, use Figure 5 A part of the adjustment work performed by applying the position adjustment method is described.

[0054] Figure 5 This is a perspective view showing the brake switch when the position adjustment tool according to the first embodiment is used.

[0055] like Figure 5 As shown, in the adjustment work, a position adjustment tool 20 is used. The position adjustment tool 20 has a thickness equal to the installation distance. The position adjustment tool 20 is sandwiched between the base 6a and the housing 14. The position adjustment tool 20 covers Figure 5 The length direction of the position adjustment tool 20 is oriented toward the length direction of the amplifying plate 6g. In this state, the distance between the base 6a and the housing 14 is equal to the mounting distance.

[0056] Next, use Figure 6 and Figure 7 The position adjustment tool 20 will be described.

[0057] Figure 6 This is a perspective view of the position adjustment tool according to the first embodiment. Figure 7 FIG. 1 is a top view of the position adjustment aid of Embodiment 1. Figure 6 and Figure 7 In the figure, the brake 6 and the brake switch 11 are not shown.

[0058] like Figure 6 As shown, the position adjustment tool 20 includes an adjustment unit 21 and an inspection unit 22. For example, the position adjustment tool 20 is produced by cutting a metal plate. The adjustment unit 21 includes a brake side unit 23, a switch side unit 24, and a storage unit 25.

[0059] The brake side portion 23 is a portion that contacts the outer surface 6s of the base 6a as a first portion during adjustment. The brake side portion 23 is divided into at least a first end portion 23a, a second end portion 23b, and a central portion 23c. The first end portion 23a is an end portion on one side in the length direction of the adjustment portion 21. The second end portion 23b is an end portion of the adjustment portion 21 opposite to one side in the length direction. The central portion 23c is a portion between the first end portion 23a and the second end portion 23b.

[0060] The first end 23a, the second end 23b, and the central portion 23c are connected by the brake side 23s. The first end 23a has a first brake side 23sa as a part of the brake side 23s. The second end 23b has a second brake side 23sb as a part of the brake side 23s different from the first brake side 23sa. The central portion 23c has a third brake side 23sc as a part of the brake side 23s. During the brake side adjustment operation, the first brake side 23sa, the second brake side 23sb, and the third brake side 23sc are in contact with the outer surface 6s.

[0061] The switch side portion 24 is a portion that contacts the housing 14 of the brake switch 11 as the second portion during the adjustment operation. The switch side portion 24 is located between the first end portion 23a and the second end portion 23b in the length direction of the position adjustment aid 20. The switch side portion 24 has a switch side portion 24s facing in the opposite direction to the brake side portion 23s. The switch side portion 24s is parallel to the brake side portion 23s. The switch side portion 24s is located at a position away from the brake side portion 23s in the thickness direction, which is a direction perpendicular to the brake side portion 23s. For example, the distance in the thickness direction between the switch side portion 24s and the brake side portion 23s is 8.0 mm.

[0062] The switch side portion 24 is provided with a first notch 24a and a second notch 24b. The first notch 24a is wider than the contact body 16 in the longitudinal direction of the position adjustment tool 20. The second notch 24b is wider than the contact body 16 in the longitudinal direction of the position adjustment tool 20.

[0063] The storage portion 25 is a groove that covers the amplifying plate 6g and the plate fixing member 6h during the adjustment operation. The storage portion 25 is located between the first end portion 23a and the second end portion 23b. The storage portion 25 is located on the side opposite to the switch side portion 24 from the switch side portion 24. The storage portion 25 is a groove surrounded by the switch side portion 24s, the first end portion 23a, the second end portion 23b, and the central portion 23c of the switch side portion 24. The storage portion 25 has a first end surface 25a and a second end surface 25b. The first end surface 25a and the second end surface 25b are opposite to each other. The first end surface 25a is a surface on the first end portion 23a side in the length direction of the position adjustment aid 20. The second end surface 25b is a surface on the second end portion 23b side in the length direction of the position adjustment aid 20.

[0064] For example, the inspection part 22 extends from the first end 23a in the longitudinal direction of the position adjustment tool 20. The inspection part 22 is formed in a plate shape. The inspection part 22 includes a first inspection part 26 and a second inspection part 27. The first inspection part 26 and the second inspection part 27 are portions of a plate having different thicknesses.

[0065] The length in the thickness direction of the first inspection portion 26, that is, the thickness, is equal to the first thickness. For example, the thickness of the first inspection portion 26 is 0.85 mm. The thickness of the second inspection portion 27 is equal to the second thickness. For example, the thickness of the second inspection portion 27 is 1.20 mm.

[0066] like Figure 7 As shown in FIG. 1 , the storage portion 25 has a width and a height that can store the amplifying plate 6g and the plate fixing member 6h. Specifically, the width W1 of the first end surface 25a and the second end surface 25b is greater than that of the first end surface 25a. Figure 4 The length L2 from the end of the plate fixing member 6h opposite to the amplifying plate 6g to the end of the operating portion 6i is longer. The depth of the storage portion 25, that is, the length in the thickness direction, is longer than the height of the plate fixing member 6h protruding from the outer surface 6s.

[0067] In the longitudinal direction of the position adjusting tool 20, the distance W2 from the first notch 24a to the second end face 25b is shorter than the length L1 from the end of the plate fixing member 6h on the side opposite to the amplifying plate 6g to the contact body 16. In the longitudinal direction of the position adjusting tool 20, the distance W3 from the second notch 24b to the first end face 25a is shorter than the length L1 from the end of the plate fixing member 6h on the side opposite to the amplifying plate 6g to the contact body 16.

[0068] use Figures 8 to 12 A method for adjusting the position of the brake switch 11 is described below. Figures 8 to 12 In FIG. 1 , a brake switch 11 a is shown as the brake switch 11 .

[0069] Figure 8 This is a perspective view of the brake switch after the temporary determination step of the position adjustment method according to the first embodiment has been performed. Fig. 9 This is a perspective view of the brake switch that performs the arrangement step of the position adjustment method according to the first embodiment. Fig.10 This is a perspective view of the brake switch after the placement step of the position adjustment method according to the first embodiment has been performed. Fig.11 This is a perspective view of the main part of the brake switch after the inspection process of the position adjustment method according to the first embodiment has been performed. Fig.12 This is a schematic diagram of the main part of the brake switch after the inspection process of the position adjustment method according to the first embodiment has been performed.

[0070] The position adjustment method in the adjustment operation includes a temporary determination process, a placement process, a fastening process, and an inspection process. First, in the adjustment operation, the temporary determination process is performed.

[0071] exist Figure 8 FIG. 1 shows a brake switch 11 that has undergone a provisional determination process. In the provisional determination process, the mounting substrate 12a and the Figure 8 The fastener 13a (not shown) holds the position of the brake switch 11 at the temporarily determined position. For example, the operator loosens the fastener 13a of the fixed brake switch 11 to hold the brake switch 11 at the temporarily determined position. For example, the operator loosely fastens the fastener 13a to the removed brake switch 11 to hold the brake switch 11 at the temporarily determined position of the mounting substrate 12a.

[0072] Afterwards, proceed Fig. 9 and Fig.10 In the configuration step, the operator positions the auxiliary tool 20. Fig. 9 The brake side surface 23s not shown in the figure is pressed against the outer surface 6s of the base 6a. At this time, the openings of the first cutout 24a and the second cutout 24b face the brake switch 11. After that, the operator presses the position adjustment tool 20 against the outer surface 6s and moves it toward the brake switch 11.

[0073] like Fig.10 As shown in FIG. 1 , the operator clamps the position adjustment tool 20 with the base 6a and the housing 14. The operator presses the housing 14 toward the base 6a. In this state, the entire side surface 23s of the brake contacts the outer surface 6s of the base 6a. Fig.10Although not shown in the figure, in the longitudinal direction of the amplifying plate 6g, the first stopper side surface 23sa and the second stopper side surface 23sb are located at a position sandwiching the amplifying plate 6g.

[0074] The amplifying plate 6g and the plate fixing member 6h are covered by the position adjustment tool 20 in the storage portion 25. Therefore, the amplifying plate 6g and the plate fixing member 6h do not contact the brake side 23s as the first portion. The brake side 23 as the second portion does not contact the surface of the amplifying plate 6g facing the brake switch 11 and the surface of the plate fixing member 6h facing the brake switch 11. In this way, the position adjustment tool 20 is arranged to be Fig.10 The outer surface 6s is contacted with the outer surface 6s so as to avoid the enlarged plate 6g and the plate fixing member 6h protruding from the outer surface 6s by the groove of the storage portion 25 (not shown).

[0075] Fig.10 The contact body 16 not shown in the figure is present at a position inside the first cutout 24a. Therefore, the contact body 16 does not contact the switch side surface 24s as the second portion. In this way, the position adjustment aid 20 contacts the housing 14 in a manner that avoids the contact body 16 protruding from the housing 14 through a cutout such as the first cutout 24a. In addition, the switch side surface 24s contacts the housing 14 at two or more locations on the surface of the housing 14 that sandwich the contact body 16 in the length direction of the amplifying plate 6g.

[0076] In this state, the fastening process is performed. In the fastening process, the operator presses the housing 14 against the position adjustment tool 20 in such a manner that the position of the brake switch 11 is maintained at the installation position, that is, in such a manner that the distance between the base 6a and the housing 14 is maintained at the installation distance, and firmly screws in the fastener 13a. The brake switch 11 is fixed to the mounting substrate 12a at the installation position. Then, the operator pulls out the position adjustment tool 20 from between the base 6a and the housing 14.

[0077] like Fig.11 As shown, the inspection process is performed after the tightening process. The operator uses the position adjustment tool 20 to inspect the operating point of the brake switch 11. Specifically, the operator inserts the inspection part 22 of the position adjustment tool 20 between the contact body 16 and the amplifier plate 6g in the closed state. The operator inserts the first inspection part 26 and the second inspection part 27 in sequence, and checks whether the electrical signal from the brake switch 11 matches the inserted parts. The inspection process includes a first inspection process and a second inspection process.

[0078] like Fig.12As shown, in the first inspection process, when the first inspection part 26 is inserted between the amplifying plate 6g and the contact body 16, the brake switch 11 does not determine that the contact body 16 is pressed. In this case, the brake switch 11 becomes a signal state that the brake 6 is in an operating state, that is, an open state. When the brake switch 11 is in a signal state indicating an open state, the operator determines that the electrical signal matches. In addition, the operator can also determine that the control electrical signal is in a signal state when the brake switch 11 itself is in a non-operating state.

[0079] In the second inspection process, when the second inspection section 27 is inserted between the amplifying plate 6g and the contact body 16, the brake switch 11 determines that the contact body 16 is pressed. In this case, the brake switch 11 becomes a signal state that the brake 6 is in a non-operating state, that is, a closed state. When the brake switch 11 is in a signal state indicating a closed state, the operator determines that the electrical signal matches. In addition, the operator can also determine that the control electrical signal is in a signal state when the brake switch 11 itself is in an operating state.

[0080] After the inspection is completed, the operator completes the adjustment work.

[0081] Next, use Fig.13 , which indicates that the position adjustment tool 20 corresponds to both the two brake switches 11a and 11b, that is, it can freely correspond to the left and right.

[0082] Fig.13 This is a perspective view of the brake switch after the placement step of the position adjustment method according to the first embodiment has been performed.

[0083] The brake switch 11b is mounted on the mounting substrate 12b at a position similar to that of the Fig.10 The brake switch 11a shown in the figure is opposite in the left and right directions. Therefore, although not shown in the figure, if you want to Fig.10 When the contact body 16 is housed inside the first notch 24a of the position adjustment tool 20 as shown, the enlarged plate 6g cannot be housed inside the housing portion 25. In this case, the entire surface of the stopper side surface 23s cannot contact the outer surface 6s.

[0084] like Fig.13 As shown, the position adjustment tool 20 is used in a posture where the contact body 16 of the brake switch 11b is accommodated in the second notch 24b. Fig.13 The distance between the first end face 25a not shown in the figure is greater than the distance from the plate fixing member 6h opposite to the brake switch 11b to Fig.13 The distance of the contact body 16 not shown in the figure is short. Fig.13 Although not shown in the figure, the amplifying plate 6g and the plate fixing member 6h can be covered by the position adjustment tool 20 inside the storage portion 25.

[0085] Since the first notch 24 a and the second notch 24 b are provided in this manner, the position adjustment tool 20 can be applied to both of the two brake switches 11 a and 11 b that are installed symmetrically.

[0086] In addition, Figures 3 to 13 In the present embodiment, an example is shown in which the plate fixing member 6h protrudes from the outer surface 6s, but the plate fixing member 6h may not protrude from the outer surface 6s. In this case, in the position adjustment aid 20, the length of the plate fixing member 6h may not be considered. That is, instead of the end of the plate fixing member 6h on the opposite side to the amplifying plate 6g, each dimension may be determined from the end of the amplifying plate 6g on the opposite side to the operating portion 6i. In addition, the plate fixing member 6h and the amplifying plate 6g may be regarded as an integrated amplifying plate 6g.

[0087] According to the first embodiment described above, the position adjustment method of the brake switch 11 includes a configuration process and a fastening process. In the configuration process, the position adjustment tool 20 is used. The position adjustment tool 20 includes a first part and a second part. The first part has a brake side 23s. The second part has a switch side 24s. The brake side 23s and the switch side 24s are separated by a mounting distance. In the configuration process, the position adjustment tool 20 is clamped by the base 6a and the housing 14. In the fastening process, the plate fixing member 6h is fastened in a state where the housing 14 is pressed against the base 6a via the position adjustment tool 20. At this time, the plate fixing member 6h is fastened in a state where the housing 14 is held in the mounting position by a force toward the base 6a. Therefore, it is possible to suppress the position of the housing 14 from being deviated from the mounting position due to the force for fastening the plate fixing member 6h and the rotational friction of the plate fixing member 6h. The difficulty of this adjustment operation is almost independent of the operator's proficiency. As a result, the operator can easily adjust the position of the brake switch 11. For example, the operator does not need to adjust and fix the position of the brake switch 11 as many times as in the past. That is, the operation time for the adjustment operation can be shortened.

[0088] In addition, the first part has a first end 23a and a second end 23b. The second part is located between the first end 23a and the second end 23b. In the configuration process and the fastening process, the position adjustment aid 20 is configured so that the amplifying plate 6g is clamped by the first end 23a and the second end 23b. By configuring in this way, the second part is opposite to the housing 14. In addition, the brake side 23s contacts the base 6a at two different points. The switch side 24s contacts the housing 14 between the first brake side 23sa and the second brake side 23sb. Therefore, the posture of the position adjustment aid 20 becomes a stable posture. It is possible to suppress the posture of the position adjustment aid 20 from changing due to the force pressed by the housing 14.

[0089] In addition, the position adjustment tool 20 includes a storage portion 25. The amplifying plate 6g includes a first end surface 25a and a second end surface 25b. The distance between the first end surface 25a and the second end surface 25b is greater than the distance L2. During the position adjustment operation, the amplifying plate 6g is stored inside the storage portion 25. For example, since the position adjustment tool 20 is not mounted on the amplifying plate 6g, it does not float up by an amount corresponding to the amplifying plate 6g. Therefore, the distance between the base 6a and the housing 14 can be more reliably maintained at the installation distance.

[0090] In addition, in the position adjustment aid 20, the second portion has a first cutout 24a. In the position adjustment method, the contact body 16 is accommodated inside the first cutout 24a. Since the contact body 16 is not mounted on the switch side 24s, the housing 14 does not float up by an amount corresponding to the contact body 16. Therefore, the distance between the base 6a and the housing 14 can be more reliably maintained at the installation distance. In addition, the housing 14 and the switch side 24s are in contact at two locations sandwiching the first cutout 24a. Therefore, when the housing 14 is pressed against the position adjustment aid 20, the posture change of the housing 14 can be suppressed.

[0091] In addition, in the position adjustment tool 20, the second portion has a first notch 24a and a second notch 24b. The first notch 24a is separated from the second end surface 25b by a distance L1. The second notch 24b is separated from the first end surface 25a by a distance L1. Therefore, the position adjustment tool 20 can be applied to either of the left and right brake switches 11a and 11b. As a result, the operator can perform the adjustment operation of the two brake switches 11a and 11b using one tool.

[0092] In addition, the position adjustment tool 20 includes an inspection unit 22. In the position adjustment method, an inspection process is performed. In the inspection process, the position adjustment tool 20 is used to check the operating point conditions of the brake switch 11. Therefore, the operator can check the operating point conditions, that is, the installation distance, using one tool.

[0093] Furthermore, the position adjustment method can also be applied to a case where the brake switch 11 is newly installed.

[0094] In addition, the switch mechanism of the brake switch 11 may also be a contact. In this case, the open / closed state of the contact changes depending on whether the contact body 16 is pressed. The signal line 15 transmits an electrical response indicating the open / closed state of the contact.

[0095] The position adjustment tool 20 may not be made of metal. The position adjustment tool 20 may be produced by joining a plurality of tools that function as the adjustment unit 21, the inspection unit 22, and the like into one.
