[0027] A mode for carrying out the present disclosure is described with reference to the drawings. Furthermore, the same reference numerals are assigned to the same or equivalent portions in each drawing. Repeated description of such portions is appropriately simplified or omitted.

[0028] Embodiment 1.

[0029] Figure 1 is a schematic view of an elevator device to which the position adjustment aid of Embodiment 1 is applied. Figure 2 is a side view of a traction machine to which the position adjustment aid of Embodiment 1 is applied.

[0030] An elevator device 1 is shown in Figure 1 An elevator device 1 is shown in

[0031] A traction machine 5 is provided in the machine room 4. The traction machine 5 is a traction machine using a permanent magnet type motor, which is called a so-called PM traction machine. The traction machine 5 is provided with two brakes 6.

[0032] A main rope 7 is wound around a rope pulley 5a of the traction machine 5. A car 8 is suspended inside the hoistway 2 on one side of the main rope 7. A counterweight 9 is suspended inside the hoistway 2 on the other side of the main rope 7. A control device 10 is provided 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 integrally control the elevator device 1.

[0033] For example, the control device 10 rotates the rope pulley 5a of the traction machine 5. The main rope 7 moves in response to the rotation of the rope pulley 5a of the traction machine 5. The car 8 and the counterweight 9 are raised and lowered in opposite directions to each other in response to the movement of the main rope 7. The control device 10 stops the rope pulley 5a of the traction machine 5 by causing the two brakes 6 to act.

[0034] As Figure 2The application of the disc brake to the traction machine 5 is shown. Specifically, the traction machine 5 has a brake disc 5b. The brake disc 5b is mechanically connected to the sheave 5a. The brake disc 5b rotates in synchronization with the sheave 5a. Two brakes 6 are installed at positions symmetrical in the left-right direction with respect to the rotation axis of the traction machine 5. The two brakes 6 are each capable of applying a braking force to the brake disc 5b.

[0035] The traction 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 and are disposed at different positions. Hereinafter, the brake switch 11a and the brake switch 11b are also representatively referred to as the brake switch 11. The brake switch 11a is disposed in one of the two brakes 6 by means of a mounting substrate 12a and a fastener 13a. The brake switch 11b is disposed in 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 each mounted to the outer surface 6s of the corresponding brake 6. That is, the brake switch 11a and the brake switch 11b are each mounted on the side opposite 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 in the left-right direction with respect to the rotation axis of the brake disc 5b. Specifically, the mounting substrate 12a is located on the side opposite the brake switch 11b with respect to the brake switch 11a. The mounting substrate 12b is located on the side opposite the brake switch 11a with respect to the brake switch 11b.

[0037] Next, the use of the brake switch 11 will be described. Figure 3 The brake 6 will be described.

[0038] Figure 3 is a schematic view of the brake to which the position adjustment aid of Embodiment 1 is applied. Furthermore, in Figure 3 , the brake switch 11a is illustrated as the brake switch 11, and the illustration of the mounting substrate 12a is omitted.

[0039] Figure 3 The brake 6 is in a state in which no braking force is applied, i.e., the operation state is the OFF state. The brake 6 is provided with a base 6a, an armature 6b, a pad 6c, a spring 6d, a suction device 6e, a transmission pin 6f, a magnification plate 6g, and a plate fastener 6h.

[0040] The base 6a constitutes the outer shape of the brake 6. A brake switch 11 is mounted on the outer surface 6s of the base 6a. The armature 6b is freely movable in the direction of the rotational axis of the brake disc 5b. The pad 6c is fixed to the armature 6b so as to oppose the brake disc 5b. The spring 6d is disposed in a compressed state between the base 6a and the armature 6b. The spring 6d applies a restoring force to the armature 6b in the direction of the brake disc 5b. The attractor 6e includes, for example, an electromagnet. In the case where a 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. Further, a similar mechanism to the pad 6c can also be provided on the opposite side across the brake disc 5b. In this case, the two pads 6c can sandwich the brake disc 5b.

[0041] The transmission pin 6f is formed in a rod shape, for example. The end portion of one side of the transmission pin 6f is fixed to the armature 6b. The transmission pin 6f penetrates the hole inside the base 6a. The end portion of the other side of the transmission pin 6f can protrude from the outer surface 6s. The amplifying plate 6g is a leaf spring. The amplifying plate 6g is elastically deformable in the length direction. The amplifying plate 6g is disposed on the outer surface 6s at the position where the hole inside the base 6a is blocked. The plate fixing member 6h is a bolt, for example. The plate fixing member 6h fixes one end of the length direction of the amplifying plate 6g to the base 6a. In this state, the amplifying 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 amplifying plate 6g. Further, the plate fixing member 6h can also be regarded as a part of the structure of the amplifying plate 6g.

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

[0043] The housing 14 constitutes the outer shape 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 an electric signal emitted by the switch mechanism to Figure 3 the control device 10 not shown in the figure. The contact body 16 is a button. The contact body 16 is supported by the housing 14 which is the outer shape. The contact body 16 protrudes from the housing 14. The switch mechanism becomes a signal state corresponding to whether or not the button is operated, that is, whether or not the contact body 16 is pressed. For example, as one of the signal states, the switch mechanism emits an electric signal only when the contact body 16 is pressed.

[0044] Although not shown, in the case where the operation state of the brake 6 is the open state, the attractor 6e does not apply an attractive force 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 is in contact with the brake disc 5b. The pad 6c applies a frictional force to the brake disc 5b as a braking force. The tip of the other side of the transmission pin 6f exists on the side inside the base 6a from the outer surface 6s. In this case, the end of the non-fixed side of the amplification plate 6g exists at a position not floating from the outer surface 6s. The end of the non-fixed side of the amplification plate 6g does not come into contact with the contact body 16. The brake switch 11 becomes a signal state indicating that the contact body 16 is not pressed. Further, in the open state, the amplification plate 6g can also come into contact with the contact body 16 to the extent that it is determined that the contact body 16 is not pressed.

[0045] As shown in Figure 3 , in the case where the operation 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 by the resultant force of the attractive force and the restoring force of the spring 6d to the base 6a. In this case, the pad 6c does not come into contact with the brake disc 5b. The tip of the other side of the transmission pin 6f protrudes to the outside of the base 6a from the outer surface 6s. The tip of the other side of the transmission pin 6f presses the central portion in the longitudinal direction of the amplification plate 6g to the brake switch 11 side. The amplification plate 6g is bent with the plate fixing member 6h as a fulcrum by being pressed by the transmission pin 6f. The end of the non-fixed side of the amplification plate 6g, that is, the operation portion 6i in the longitudinal direction opposite the plate fixing member 6h presses the contact body 16. The brake switch 11 becomes a signal state indicating that the contact body 16 is pressed. Here, the distance by which the operation portion 6i moves is greater than the amount by which the transmission pin 6f protrudes from the outer surface 6s. That is, the amplification plate 6g functions to amplify and transmit the amount by which the transmission pin 6f protrudes from the outer surface 6s.

[0046] Next, the installation position of the brake switch 11 will be described with reference to FIG. 8. Figure 4 The installation position of the brake switch 11 will be described with reference to FIG. 8.

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

[0048] The amplification plate 6g in the case where the brake 6 is in the open state is shown in Figure 4 . The housing 14 of the brake switch 11 is fixed to the installation position. The installation position is a distance at which the operation point of the contact body 16 satisfies the condition. Therefore, the brake switch 11, in the case where it is in the installation position, is able to detect the operation state of the brake 6.

[0049] In a case where the brake switch 11 is in the installed position, the length from the end of the plate fixing member 6h on the side opposite the magnifying plate 6g to the contact 16 in the length direction of the magnifying plate 6g is LI. In addition, the length from the end of the plate fixing member 6h on the side opposite the magnifying plate 6g to the tip of the operation portion 6i is L2.

[0050] In addition, the installed position is a position at which the distance between the contact 16 and the magnifying plate 6g in the opened state is apart from the prescribed operation distance. For example, in a case where the brake switch 11 is in the installed position, even if an object having a first thickness is interposed between the operation portion 6i and the contact 16, it is not determined that the contact 16 is pressed. In a case where an object having a second thickness is interposed between the operation portion 6i and the contact 16 in the opened state, it is determined that the contact 16 is pressed. In a case where these determinations are made, the condition of the operation point is satisfied.

[0051] Specifically, the operation distance equal to the first thickness is 0.85 mm. The second thickness is 1.20 mm. In this case, when the contact 16 is moved by 0.35 mm or more, it is determined that the contact 16 is pressed. In this way, the precision required of the installed position of the brake switch 11 is very high.

[0052] In a case where the brake switch 11 is in the installed position, the distance between the housing 14 and the outer surface 6s of the base 6a is apart from the prescribed installed distance L3. The installed distance L3 differs depending on the type of the brake 6, that is, the type of the hauler 5. For example, the installed distance L3 is 8.0 mm. In the position adjustment method of the present embodiment, the installed distance L3 is utilized.

[0053] Next, a part of the adjustment work performed using the position adjustment aid 20 will be described. Figure 5 A part of the adjustment work performed using the position adjustment aid 20 will be described.

[0054] Figure 5 A perspective view of the brake switch when the position adjustment aid of Embodiment 1 is used is shown.

[0055] As shown in FIG. 6, in the adjustment work, the position adjustment aid 20 is used. The position adjustment aid 20 has a thickness equal to the installed distance. The position adjustment aid 20 is sandwiched by the base 6a and the housing 14. The position adjustment aid 20 covers the magnifying plate 6g, which is not shown in FIG. 6. Figure 5 The length direction of the position adjustment aid 20 is oriented in the length direction of the magnifying plate 6g. In this state, the distance between the base 6a and the housing 14 is equal to the installed distance. Figure 5

[0056] Next, the position adjustment aid 20 will be described. Figure 6 Figure 7

[0057] ​​​Figure 6 is a perspective view of the position adjustment aid of Embodiment 1. Figure 7 is a plan view of the position adjustment aid of Embodiment 1. In addition, in Figure 6 and Figure 7 , the brake 6 and the brake switch 11 are not illustrated.

[0058] As shown in Figure 6 , the position adjustment aid 20 is provided with an adjustment portion 21 and an inspection portion 22. The position adjustment aid 20 is manufactured by, for example, machining such as cutting processing on a metal plate. The adjustment portion 21 is provided with a brake-side portion 23, a switch-side portion 24, and a housing portion 25.

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

[0060] The first end portion 23a, the second end portion 23b, and the central portion 23c are connected by a brake-side surface 23s. The first end portion 23a has a first brake-side surface 23sa that is a part of the brake-side surface 23s. The second end portion 23b has a second brake-side surface 23sb that is a part of the brake-side surface 23s different from the first brake-side surface 23sa. The central portion 23c has a third brake-side surface 23sc that is a part of the brake-side surface 23s. The first brake-side surface 23sa, the second brake-side surface 23sb, and the third brake-side surface 23sc contact the outer surface 6s at the time of the brake-side adjustment work.

[0061] The switch-side portion 24 is a portion that contacts the housing 14 of the brake switch 11 at the time of the adjustment work as a second portion. 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 surface 24s that faces in a direction opposite to the brake-side surface 23s. The switch-side surface 24s is parallel to the brake-side surface 23s. The switch-side surface 24s is located at a position that is apart from the brake-side surface 23s by a mounting distance in a direction perpendicular to the brake-side surface 23s, that is, a thickness direction. For example, the distance in the thickness direction between the switch-side surface 24s and the brake-side surface 23s is 8.0 mm.

[0062] A first cutout 24a and a second cutout 24b are provided on the switch side 24. In the length direction of the position adjustment aid 20, the width of the first cutout 24a is wider than the width of the contact body 16. In the length direction of the position adjustment aid 20, the width of the second cutout 24b is wider than the width of the contact body 16.

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

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

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

[0066] like Figure 7 As shown, the storage section 25 has a width and height capable of accommodating the enlarged plate 6g and the plate fixing member 6h. Specifically, the width W1 of the first end face 25a to the second end face 25b is from... Figure 4 The length L2 from the end of the plate fixing member 6h opposite to the enlarged plate 6g to the end of the actuating part 6i is longer. The depth of the receiving part 25, i.e., its 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 positioning aid 20, the distance W2 from the first cut 24a to the second end face 25b is shorter than the length L1 from the end of the plate fixing member 6h opposite to the magnifying plate 6g to the contact body 16. In the longitudinal direction of the positioning aid 20, the distance W3 from the second cut 24b to the first end face 25a is shorter than the length L1 from the end of the plate fixing member 6h opposite to the magnifying plate 6g to the contact body 16.

[0068] useFigures 8 to 12 The position adjustment method of the brake switch 11 will be described. In Figures 8 to 12 , the brake switch 11a is shown as the brake switch 11.

[0069] Figure 8 is a perspective view of the brake switch on which the temporary determination process of the position adjustment method of Embodiment 1 is performed. Figure 9 is a perspective view of the brake switch on which the arrangement process of the position adjustment method of Embodiment 1 is performed. Figure 10 is a perspective view of the brake switch on which the arrangement process of the position adjustment method of Embodiment 1 is performed. Figure 11 is a perspective view of the main part of the brake switch on which the inspection process of the position adjustment method of Embodiment 1 is performed. Figure 12 is a schematic view of the main part of the brake switch on which the inspection process of the position adjustment method of Embodiment 1 is performed.

[0070] The position adjustment method in the adjustment work has the temporary determination process, the arrangement process, the fastening process, and the inspection process. First, in the adjustment work, the temporary determination process is performed.

[0071] In Figure 8 , the brake switch 11 on which the temporary determination process is performed is shown. In the temporary determination process, the position of the brake switch 11 is held at the temporarily determined position by the mounting substrate 12a and the fastener 13a not shown in Figure 8 . For example, the worker holds the brake switch 11 at the temporarily determined position by loosening the fastener 13a of the fixed brake switch 11. For example, the worker holds the brake switch 11 at the temporarily determined position of the mounting substrate 12a by loosely fixing the fastener 13a to the detached brake switch 11.

[0072] After that, the arrangement process and the fastening process as shown in Figure 9 and Figure 10 are performed. In the arrangement process, the worker presses the brake-side surface 23s of the position adjustment aid 20 not shown in Figure 9 to the outer surface 6s of the base 6a. At this time, the opening portions of the first cutout 24a and the second cutout 24b face the brake switch 11. After that, the worker presses the position adjustment aid 20 to the outer surface 6s and moves it in the direction of the brake switch 11.

[0073] As shown in Figure 10 , the worker sandwiches the position adjustment aid 20 with the base 6a and the housing 14. The worker presses the housing 14 to the base 6a side. In this state, the brake-side surface 23s as a whole is in contact with the outer surface 6s of the base 6a. At this time, although the brake switch 11 is not shown in Figure 10The first brake-side surface 23sa and the second brake-side surface 23sb are positioned to sandwich the magnifying plate 6g in the length direction of the magnifying plate 6g.

[0074] The magnifying plate 6g and the plate fixing member 6h are covered by the position adjustment aid 20 in the housing portion 25. Therefore, the magnifying plate 6g and the plate fixing member 6h do not come into contact with the brake-side surface 23s as the first portion. The brake-side surface 23 as the second portion does not come into contact with the surface of the magnifying 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 aid 20 comes into contact with the outer surface 6s in a manner that avoids the magnifying plate 6g and the plate fixing member 6h protruding from the outer surface 6s by the groove of the housing portion 25 not illustrated. Figure 10

[0075] Figure 10 The contact body 16 not illustrated is present at a position inside the first cutout 24a. Therefore, the contact body 16 does not come into contact with the switch-side surface 24s as the second portion. In this way, the position adjustment aid 20 comes into contact with the housing 14 in a manner that avoids the contact body 16 protruding from the housing 14 by the cutout like the first cutout 24a. In addition, the switch-side surface 24s comes into contact with the housing 14 at two or more positions in the surface of the housing 14 sandwiching the contact body 16 in the length direction of the magnifying plate 6g.

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

[0077] As shown in FIG. 6, a checking process is performed after the fastening process. The worker performs a check of the action point of the brake switch 11 using the position adjustment aid 20. Specifically, the worker inserts the checking portion 22 of the position adjustment aid 20 between the contact body 16 and the magnifying plate 6g in the off state. The worker sequentially inserts the first checking portion 26 and the second checking portion 27, and checks whether the electric signal from the brake switch 11 matches the inserted portion. The checking process includes a first checking process and a second checking process. Figure 11

[0078] Figure 12 ​​​As shown, in the first inspection process, when the first inspection part 26 is inserted between the amplification 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 indicating that the brake 6 is in the activated state, i.e., the open state. When the brake switch 11 is in the signal state indicating the open state, the operator determines that the electrical signal is matched. In addition, the operator can also determine that the brake switch 11 itself is in the signal state of being in the non-activated state as a control electrical signal.

[0079] In the second inspection process, when the second inspection section 27 is inserted between the amplification 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 indicating that the brake 6 is in a non-operational state, i.e., a closed state. When the brake switch 11 is in a signal state indicating a closed state, the operator determines that the electrical signal is matched. Alternatively, the operator can also determine that the brake switch 11 itself is in an operation state as a control electrical signal.

[0080] After the inspection was completed, the workers finished the adjustment work.

[0081] Next, use Figure 13 This indicates that the position adjustment accessory 20 corresponds to both the two brake switches 11a and 11b, meaning they are freely corresponding to each other on the left and right.

[0082] Figure 13 This is a perspective view of a brake switch that has undergone the configuration process of the position adjustment method of Embodiment 1.

[0083] Brake switch 11b is mounted on mounting base plate 12b at the same position as Figure 10 The brake switch 11a shown is reversed in the left-right direction. Therefore, although not shown, it is possible to achieve the desired effect as described above. Figure 10 When the contact body 16 is housed inside the first cut 24a of the position adjustment aid 20 as shown, the enlarged plate 6g cannot be housed inside the housing 25. In this case, the entire surface of the brake side 23s cannot contact the outer surface 6s.

[0084] like Figure 13 As shown, the position adjustment accessory 20 is used in a position to house the contact body 16 of the brake switch 11b inside the second cut 24b. The second cut 24b and Figure 13 The distance between the first end faces 25a (not shown) is from the plate fixing member 6h opposite the brake switch 11b to... Figure 13 The distance to contact body 16 (not shown) is short. Therefore, although in Figure 13 Although not shown in the diagram, the enlarged plate 6g and the plate fixing member 6h can be covered by the position adjustment auxiliary 20 inside the storage part 25.

[0085] Thus, since the first cutout 24a and the second cutout 24b are provided, the position adjustment aid 20 can be applied to both of the brake switches 11a, 11b which are installed in left-right symmetry.

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

[0087] According to the position adjustment method of the brake switch 11 of the above-described embodiment 1, the method includes a disposition step and a fastening step. In the disposition step, the position adjustment aid 20 is used. The position adjustment aid 20 includes a first portion and a second portion. The first portion has a brake side surface 23s. The second portion has a switch side surface 24s. The brake side surface 23s is apart from the switch side surface 24s by a mounting distance. In the disposition step, the position adjustment aid 20 is sandwiched by the base 6a and the housing 14. In the fastening step, the plate fixing member 6h is fastened in a state in which the housing 14 is pressed against the base 6a with the position adjustment aid 20 interposed therebetween. At this time, the plate fixing member 6h is fastened in a state in which the housing 14 is held in the mounting position by a force toward the base 6a. Thus, the position of the housing 14 from the mounting position due to a force for fastening the plate fixing member 6h and rotational friction of the plate fixing member 6h can be suppressed. The degree of difficulty of the adjustment work is hardly dependent on the proficiency of the worker. As a result, the worker can easily adjust the position of the brake switch 11. For example, the worker does not adjust and fix the position of the brake switch 11 as many times as in the past. That is, the working time of the adjustment work can be shortened.

[0088] Further, the first portion has a first end portion 23a and a second end portion 23b. The second portion is located between the first end portion 23a and the second end portion 23b. In the disposition step and the fastening step, the position adjustment aid 20 is disposed so as to sandwich the magnification plate 6g by the first end portion 23a and the second end portion 23b. By thus disposing, the second portion opposes the housing 14. Further, the brake side surface 23s contacts the base 6a at two different points. The switch side surface 24s contacts the housing 14 between the first brake side surface 23sa and the second brake side surface 23sb. Thus, the posture of the position adjustment aid 20 becomes a stable posture. The change in the posture of the position adjustment aid 20 due to a force pressed by the housing 14 can be suppressed.

[0089] Further, the position adjustment aid 20 is provided with a housing portion 25. The magnification plate 6g has 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 farther than the distance L2. In the position adjustment work, the magnification plate 6g is housed inside the housing portion 25. For example, the position adjustment aid 20 does not float by the amount corresponding to the magnification plate 6g because it is not mounted on the magnification plate 6g. Therefore, the distance between the base 6a and the housing 14 can be more reliably maintained as the mounting distance.

[0090] Further, in the position adjustment aid 20, the second portion has a first cutout 24a. In the position adjustment method, the contact body 16 is housed inside the first cutout 24a. The housing 14 does not float by the amount corresponding to the contact body 16 because the contact body 16 is not mounted on the switch side surface 24s. Therefore, the distance between the base 6a and the housing 14 can be more reliably maintained as the mounting distance. Further, the housing 14 and the switch side surface 24s are in contact at two portions sandwiching the first cutout 24a. Therefore, in the case where the housing 14 is pressed against the position adjustment aid 20, the posture change of the housing 14 can be suppressed.

[0091] Further, in the position adjustment aid 20, the second portion has a first cutout 24a and a second cutout 24b. The first cutout 24a is apart from the second end surface 25b by the distance Ll. The second cutout 24b is apart from the first end surface 25a by the distance Ll. Therefore, the position adjustment aid 20 can be applied to either of the left and right brake switches 11a, 11b. As a result, the worker can perform the adjustment work of the two brake switches 11a, 11b by one aid.

[0092] Further, the position adjustment aid 20 is provided with an inspection portion 22. In the position adjustment method, an inspection process is performed. In the inspection process, the confirmation of the condition of the operation point of the brake switch 11 is performed using the position adjustment aid 20. Therefore, the worker can perform the confirmation of the condition of the operation point, that is, the inspection of the mounting distance, by one aid.

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

[0094] Further, the switch mechanism of the brake switch 11 can also be a contact. In this case, the open / close state of the contact changes depending on whether or not the contact body 16 is pressed. The signal line 15 transmits an electrical response indicating the open / close state of the contact.

[0095] Further, the position adjustment aid 20 can also not be metallic. The position adjustment aid 20 can also be made by joining a plurality of aids each of which functions as the adjustment portion 21, the inspection portion 22, and the like, into one.
