  The present invention relates to a pressing member provided on an interior panel of an automobile or the like and an operation panel of various electronic devices.

  2. Description of the Related Art Conventionally, a pressing member provided so as to be able to be pushed into the operation panel is known.

  This kind of pressing member is provided with a light guide member that guides the light irradiated on the back side of the operation panel to the pressing surface, and this light guide member displays predetermined information to the operator. (For example, patent document 1) is known.

  As shown in FIG. 7, the illumination switch device of Patent Document 1 includes a substrate 101 that holds an LED 103, and a slide 105 that turns a contact mechanism (not shown) on and off by sliding up and down with respect to the substrate 101. A light guide (light guide member) held by the slide 105 in a state of being exposed to the outside of the knob 107 through an opening 107a penetrating the knob 107 in the vertical direction. ) 106, and the light guide 106 guides the light emitted from the LED 103 to the outside of the knob 107.

Specifically, the slide 105 is provided with a hollow portion penetrating in the vertical direction, and the knob 107 is formed in a bottomed container shape so as to cover an upper surface and a side surface of the slide 105, and the bottom of the knob has the An opening 107a is formed. A ride guide 106 is fitted into the hollow portion of the slide 105 from above, and a first protrusion 165 of the ride guide 106 that protrudes upward from the slide 105 is formed with respect to the opening 107 a of the knob 107. A knob 107 is put on the upper end of the slide 105 so as to be fitted from below and to cover the upper surface and the side surface of the slide 105.
JP-A-2005-11885

  By the way, in the configuration in which the light emitted from the LED 103 is guided to the surface (pressing surface) of the knob 107 through the ride guide 106 as in the illumination switch device of Patent Document 1, the light is guided to the first protrusion 165 of the ride guide 106. In order to clearly show the emitted light to the operator, it is desired to make the gap between the first protrusion 165 and the opening 107a as small as possible when the knob 107 is viewed from the pressing surface side.

  On the other hand, when assembling the illumination switch device of Patent Document 1, the light guide 106 is inserted into the hollow portion of the slide 105 from above, and the knob 107 is put on the slide 105 from above. However, when assembling in this way, the upper end of the slide 105 is covered with a knob so as to cover the upper surface and the side surface of the slide 105, and the first protrusion 165 of the light guide 106 is moved to the knob 107 at an inner position of the knob 107. During this operation, the first protrusion 165 is hidden by the side wall 108 of the knob 107, and the first protrusion 165 is inserted into the knob opening 107a. I could not work while confirming. Therefore, when assembling in this way, the smaller the gap between the first protrusion 165 and the opening 107a as described above, the more the first protrusion 165 becomes at the edge of the opening 107a of the knob 107. There is a high possibility that the first projecting portion 165 is damaged due to contact.

  Here, in the stage before the light guide 106 is inserted into the slide 105, the first projecting portion 165 is fitted into the opening 107 a of the knob 107, and then the knob 107 is put on the slide 105 from above. However, in this case, it is necessary for the operator to first fit the light guide 106 into the knob 107 and then to cover the slide 107 with the knob 107. Since the part to be assembled is changed, the part to be assembled is picked up and the assembly direction is changed. As a result, the workability is worse than in the above case where the part to be assembled can be shared by the slide 105.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a pressing member that can suppress breakage of the light guide member while maintaining good workability, and a pressing operation device including the pressing member. Yes.

  In order to solve the above-described problems, the present invention provides a moving member that is provided so as to be movable in a specific operation direction with respect to a substrate that holds a light source, and that can press a switch held on the substrate in accordance with this movement. And a top plate that is disposed so as to cover the distal end surface of the moving member in the operation direction and has a window portion that penetrates in the operation direction, and surrounds a side surface of the moving member in a lateral direction orthogonal to the operation direction. A covering member having a side plate capable of being held, a holding portion held by the moving member, and an insertion portion inserted into the window portion of the top plate while the holding portion is held, A light guide member capable of receiving light emitted from a light source from the holding portion and guiding the light to the insertion portion, and a surface surrounding the window portion is widened toward the moving member in the operation direction. The lateral gap between the inner side surface constituting the maximum opening end of the guiding surface and the side surface of the distal end portion of the insertion portion is between the side surface of the moving member and the side plate of the covering member. A surface that surrounds the window portion and a side surface of the distal end portion of the insertion portion when the insertion portion is inserted to a predetermined insertion position with respect to the window portion, and is set to be larger than the lateral gap. The pressing member is characterized in that the lateral gap between the two is set smaller than the lateral gap between the side surface of the moving member and the side plate of the covering member.

  According to the present invention, since the surface surrounding the window portion includes a guide surface that spreads toward the moving member, when the insertion portion is inserted into the window portion, the distal end portion of the insertion portion is moved from the normal insertion position. Even if it is misaligned in the lateral direction, if it is within the range of the inner surface that constitutes the maximum opening end of the guiding surface, the insertion portion is placed along the inner surface (the guiding surface) in the deep portion of the window portion. Can lead to.

  Further, in the present invention, the lateral gap between the inner side surface constituting the maximum opening end of the guiding surface and the side surface of the distal end of the insertion portion is the lateral direction between the side surface of the moving member and the side plate of the covering member. The gap is set to be larger than the gap of the moving member, so that the inner surface of the side plate of the covering member is slid with respect to the side surface of the moving member so that the moving member covers the moving member. The inserted portion of the light guide member is necessarily inserted into the window portion.

  The insertion portion has a predetermined insertion position with respect to the window portion, that is, a lateral gap between the surface surrounding the window portion and the side surface of the distal end portion of the insertion portion has a side surface of the moving member and the covering member. Insertion is performed up to an insertion position smaller than the lateral gap between the side plates. Therefore, in the case where the guiding surface is not formed as in the prior art, the insertion portion is inserted when these members move laterally by the gap between the side surface of the moving member and the side plate of the covering member. It is possible to guide the insertion portion to a range where the insertion cannot be performed without damaging the insertion portion by the guide by the guide surface.

  That is, according to the present invention, it is possible to guide the insertion portion to a preset insertion position without damaging the insertion portion by the guiding surface that spreads toward the moving member, and between the insertion portion and the window portion at the insertion position. By reducing the gap between them, it is possible to achieve both the advantage of ensuring good appearance when the covering member is viewed from the surface side.

  Furthermore, even when the procedure of covering the moving member with the light guide member held by the moving member and applying the covering member to the moving member is adopted, the insertion portion and the window portion hidden behind the covering member are not visible. Can be reliably inserted.

  Therefore, according to the present invention, the covering member is put on the moving member holding the light guide member without changing the work procedure in which the insertion portion of the light guide member is inserted into the window portion in advance. As a result, the insertion portion can be guided to a preset insertion position along the guiding surface, so that breakage of the light guide member (insertion portion) can be suppressed while maintaining good workability.

  In the pressing member, the window portion includes, in addition to the guiding surface, an accommodation surface that extends straight from the inner surface that forms the minimum opening end of the guiding surface in the operation direction and is connected to the surface of the top plate. Preferably, the insertion portion is formed in such a length that the distal end portion is accommodated inside the accommodation surface in a state where the insertion portion is inserted to a preset insertion position with respect to the window portion.

  If it does in this way, the clearance gap between the front-end | tip part of an insertion part and the inner surface of a window part can be made into the clearance gap between the front-end | tip part of this insertion part, and the accommodation surface formed in the straight. Therefore, the gap size can be reliably managed.

  In the pressing member, the moving member is formed with a holding hole penetrating in the operation direction, and the holding portion is inserted into the moving member by being inserted into the holding hole from the distal end side of the moving member. The covering member and the moving member each have an engaging portion that engages with each other, and the engaging member is placed on the moving member from the front end side of the moving member. It is preferable that the covering member and the moving member are engaged with each other so as to prevent relative movement in the direction in which they are separated.

  According to this configuration, the light guide member (holding portion) is inserted into the moving member from the distal end side of the moving member, and the covering member is covered with the moving member, whereby the covering member and the moving member are respectively engaged by the engaging portions. Since the assembly direction of each of these members can be unified (the direction from the distal end portion to the proximal end portion of the moving member in the operation direction), the workability can be further improved. .

  The pressing member further includes an insertion restricting means capable of restricting movement of the holding portion in the insertion direction with respect to the moving member in a state where the insertion position of the holding portion with respect to the holding hole has reached a specific insertion position. It is preferable.

  In this way, when the light guide member is assembled to the moving member, the insertion position of the holding portion with respect to the holding hole can be limited at the specific insertion position. Unlike the case where the operator performs the insertion operation of the light guide member while worrying about the insertion position, it is only necessary to perform the insertion operation uniformly up to the specific insertion position. Workability can be improved.

  Furthermore, in the said structure, even when a light guide member (insertion part) is pressed through the said window part, when the coating | coated member is pressed after attaching a moving member and a coating | coated member, the said light guide It is possible to prevent the member from moving to the back of the moving member.

  In the pressing member, in a state where the insertion position of the holding portion with respect to the holding hole has reached a specific insertion position, the holding member is restricted from moving in a direction opposite to the insertion direction with respect to the moving member. It is preferable to further include a possible retaining means.

  In this way, after the light guide member is assembled to the moving member, before the covering member is covered, even if the weight of the light guide member acts in the direction of pulling out the light guide member from the moving member, It is possible to prevent the light guide member from dropping from the member.

  Specifically, the retaining means is elastically deformed inward in response to being inserted into the holding hole provided in the light guide member, and outward when the holding portion has reached the specific insertion position. A leaf spring portion that elastically returns, and a regulating surface that restricts the movement member from moving in a direction in which the holding portion comes out by contacting the distal end portion of the leaf spring portion that is provided on the moving member and elastically returns. It can be set as the structure provided with.

  If it does in this way, a leaf | plate spring part will elastically return by inserting a light guide member with respect to a moving member to the said specific insertion position, and the front-end | tip part of this leaf | plate spring part and the control surface of a moving member will contact | abut. Thus, the light guide member can be prevented from coming off from the moving member.

  Further, the leaf spring portion is set to an urging force capable of maintaining the insertion position of the holding portion with respect to the moving member by elastically deforming and pressing the inner surface of the holding hole. The covering member preferably includes a pressing portion that presses the holding portion whose insertion position is maintained by the urging force of the leaf spring portion into the holding hole in accordance with being put on the moving member.

  In this way, the insertion position of the light guide member relative to the moving member can be maintained by the urging force of the leaf spring portion pressed against the inner surface of the holding hole, and the covering member includes the pressing portion. Even when the insertion depth of the light guide member with respect to the moving member is incomplete, the holding portion can be inserted into the holding hole by the pressing portion of the covering member by subsequently covering the moving member with the covering member. Therefore, after the light guide member is incompletely inserted into the moving member, before the covering member is put on the moving member, the weight of the light guide member is pulled in the direction in which the light guide member is pulled out of the moving member. Even if it is added, the light guide member can be properly inserted into the moving member by covering the cover member without performing a separate operation of inserting the light guide member while preventing the light guide member from falling off. It is possible to insert up to the position.

  In the pressing member, the light guide member has at least part of a sandwiched portion that can be sandwiched between the covering member and the moving member, and the covering member is in a state in which the engaging portions are engaged with each other. It is preferable that movement of the light guide member in the operation direction is restricted by sandwiching the sandwiched portion between the movable member and the movable member.

  In this way, it is possible to suppress rattling in the operation direction of the light guide member after covering the moving member with the covering member, and accordingly, the insertion portion visually recognized from the outside through the window portion of the covering member. Since rattling can be suppressed, it is possible to suppress a change in the appearance of light guided from the light source to the insertion portion.

  Furthermore, the present invention provides a substrate, a light source and a switch provided on the substrate, the pressing member according to any one of claims 1 to 6, and the pressing member in a specific operation direction with respect to the substrate. A pressing operation device including a supporting member that is movably supported, wherein the moving member presses the switch in the operation direction in response to the covering member being operated in a specific operation direction. A pressing operation device is provided.

  According to the present invention, since the surface surrounding the window portion includes a guide surface that spreads toward the moving member, when the insertion portion is inserted into the window portion, the distal end portion of the insertion portion is moved from the normal insertion position. Even if it is misaligned in the lateral direction, if it is within the range of the inner surface that constitutes the maximum opening end of the guiding surface, the insertion portion is placed along the inner surface (the guiding surface) in the deep portion of the window portion. Can lead to.

  Further, in the present invention, the lateral gap between the inner side surface constituting the maximum opening end of the guiding surface and the side surface of the distal end of the insertion portion is the lateral direction between the side surface of the moving member and the side plate of the covering member. The gap is set to be larger than the gap of the moving member, so that the inner surface of the side plate of the covering member is slid with respect to the side surface of the moving member so that the moving member covers the moving member. The inserted portion of the light guide member is necessarily inserted into the window portion.

  The insertion portion has a predetermined insertion position with respect to the window portion, that is, a lateral gap between the surface surrounding the window portion and the side surface of the distal end portion of the insertion portion has a side surface of the moving member and the covering member. Insertion is performed up to an insertion position smaller than the lateral gap between the side plates. Therefore, in the case where the guiding surface is not formed as in the prior art, the insertion portion is inserted when these members move laterally by the gap between the side surface of the moving member and the side plate of the covering member. It is possible to guide the insertion portion to a range where the insertion cannot be performed without damaging the insertion portion by the guide by the guide surface.

  That is, according to the present invention, it is possible to guide the insertion portion to a preset insertion position without damaging the insertion portion by the guiding surface that spreads toward the moving member, and between the insertion portion and the window portion at the insertion position. By reducing the gap between them, it is possible to achieve both the advantage of ensuring good appearance when the covering member is viewed from the surface side.

  Furthermore, even when the procedure of covering the moving member with the light guide member held by the moving member and applying the covering member to the moving member is adopted, the insertion portion and the window portion hidden behind the covering member are not visible. Can be reliably inserted.

  Therefore, according to the present invention, the covering member is put on the moving member holding the light guide member without changing the work procedure in which the insertion portion of the light guide member is inserted into the window portion in advance. As a result, the insertion portion can be guided to a preset insertion position along the guiding surface, so that breakage of the light guide member (insertion portion) can be suppressed while maintaining good workability.

The switch 5 (not shown) on the electronic board 2 is pressed by the lower surface of the switch 5 so that the moving member 5 is disposed right above the switch.

  The moving member 5 is a cylindrical synthetic resin member extending in the operation direction D1. That is, the moving member 5 has a holding hole 8 penetrating in the operation direction D1 in which the cross-sectional shape in the lateral direction perpendicular to the operation direction D1 is formed in a substantially rectangular shape. In the following description, the longitudinal direction of the rectangular cross section of the lateral direction orthogonal to the operation direction D1 is the left-right direction and the short direction is the up-down direction.

  Of the four side surfaces (upper surface 5a, lower surface 5b, right surface 5c and left surface 5d) of the moving member 5, a pair of left and right claws 9 are formed on the upper surface 5a and the lower surface 5b, respectively, as shown in FIGS. (The lower surface 5b is not shown). These claw portions 9 protrude outward from the upper surface 5a and the lower surface 5b, and engage with a knob 6 described later.

  The holding hole 8 has an opening shape that is wide in the left-right direction and narrow in the up-down direction, corresponding to the cross-sectional shape of the lens 7 described later, and is disposed above the LED 3. Further, on the left and right inner side surfaces 8a and 8b surrounding the holding hole 8, as shown in FIG. 4, the convex portions 10 and the convex portions 11 are respectively formed on the counterpart inner side surfaces 8a and 8b over a predetermined range in the operation direction D1. Projected toward. On the other hand, as shown in FIG. 3, the upper and lower inner side surfaces 8c and 8d surrounding the holding hole 8 are formed with projections 12 and projections 14 projecting toward the counterpart inner side surfaces 8c and 8d, respectively.

  The knob 6 is a bottomed container-shaped synthetic resin member integrally including a top plate 15 capable of covering the distal end surface of the moving member 5 and a side plate 16 capable of surrounding side surfaces 5a to 5d of the moving member. is there.

  The top plate 15 has a surface 15a serving as a pressing surface 15a that receives an operation by an operator. On the other hand, on the back surface of the top plate 15, there is provided a standing portion 17 erected on the electronic substrate 2 side, and penetrates from the end surface 17 a to the pressing surface 15 a of the standing portion 17 in the operation direction D 1. A window 18 is provided.

  The window portion 18 has an opening shape that is wide in the left-right direction and narrow in the up-down direction corresponding to the shape of the insertion portion 25 of the lens 7 described later. The window 18 constitutes a tapered surface (leading surface) 19 that is tapered from the end surface 17 a of the standing portion 17 toward the opposite pressing surface 15 a, and the minimum opening end of the tapered surface 19. And an accommodating surface 20 that extends straight in the operation direction D1 from the inner side surface and is connected to the pressing surface 15a. An end surface 17 a of the upright portion 17 is configured to sandwich a part of a lens 7 to be described later with the moving member 5.

  The side plate 16 includes a covering upper surface 16a for covering the upper surface 5a of the moving member 5, a covering lower surface 16b for covering the lower surface 5b of the moving member 5, and a covering right surface 16c for covering the right surface 5c of the moving member 5. A covering left surface 16d for covering the left surface 5d of the moving member 5 is provided.

  The covering upper surface 16a and the covering lower surface 16b are respectively provided with a pair of left and right locking windows 21 penetrating in the vertical direction (see FIGS. 1 and 2; the covering lower surface 16b is not shown). These locking windows 21 are provided at positions where the respective claws 9 can be received in a state in which the knob 6 is inserted to the moving member 5 to a preset insertion position (position shown in FIG. 4). Yes. Therefore, the knob 6 and the moving member 5 assembled so as to be in the insertion position are connected so as not to be relatively movable in the operation direction D1.

  In this embodiment, as shown in FIG. 4, the inner dimension X1 between the coated upper surface 16a and the coated lower surface 16b and the outer dimension X2 between the upper surface 5a and the lower surface 5b are respectively left and right. While the gap G1 is provided, as shown in FIG. 3, there is a vertical gap between the inner dimension Y1 between the coated right surface 16c and the coated left surface 16d and the outer dimension Y2 between the right surface 5c and the left surface 5d. Each is provided with a gap G2.

  The lens 7 is a synthetic resin plate made of an acrylic resin or the like set to a thickness and a width dimension that can be inserted into the holding hole 8 from the distal end side of the moving member 5. Specifically, the lens 7 includes a holding portion 22 held by the moving member, a pair of restricting pieces 23 and restricting pieces 24 protruding from the holding portion 22 in the left-right direction, and the holding portion 22 on the moving member 5. It is integrally provided with an insertion portion 25 that is inserted into the window portion 18 of the top plate 15 while being held, and can receive light emitted from the LED 3 from the holding portion 22 and guide it to the insertion portion 25. ing.

  The holding portion 22 is set to have a left-right width dimension that can be inserted into the holding hole 8 through the convex portions 10 and 11. A leaf spring portion 26 and a leaf spring portion 27 are respectively provided on the left and right side surfaces of the holding portion 22. The leaf spring portions 26 and 27 are elastically deformable in the left-right direction at their tip portions with the electronic substrate 2 side as a fulcrum. Accordingly, when the holding portion 22 is inserted into the holding hole 8, the leaf spring portions 26 and 27 are elastically deformed inward between the convex portions 10 and 11, and the holding portion 22 is moved to a preset insertion position. When inserted, the leaf springs 26 and 27 get over the projections 10 and 11 and elastically return to the outside. In this state of elastic recovery, the free ends of the leaf spring portions 26 and 27 are in contact with the side surfaces 10a or 11a of the convex portions 10 and 11, respectively, even if the lens 7 is moved in the pulling direction. Is prevented from coming off the moving member 5. Further, as shown in FIG. 6, each leaf spring portion 26, 27 holds the weight of the lens 7 so that the insertion position is maintained when the holding portion 22 is not inserted up to the insertion position. It has an urging force that can

  Further, as shown in FIG. 3 and FIG. 4, a protrusion 28, a protrusion 29, a protrusion 30, and a protrusion 31 are provided on the left and right side surfaces and the upper and lower side surfaces of the holding portion 22, respectively. The backlash in the lateral direction of the lens 7 in the holding hole 8 is suppressed by coming into contact with the inner side surfaces of the convex portions 10 and 11 or the inner side surfaces of the projections 12 and 14, respectively.

  The restricting pieces 23 and 24 move by contacting the side surface 10b or the side surface 11b of the convex portions 10 and 11, respectively, when the holding portion 22 is inserted to a preset insertion position with respect to the moving member 5. The lens 7 is further prevented from being inserted into the member 5. Further, when the knob 6 is put on the moving member 5, the regulating pieces 23 and 24 are sandwiched between the end surface 17a of the knob 6 and the side surfaces 10b and 11b of the convex portions 10 and 11. It has become. Therefore, in the state where the knob 6 is placed on the moving member 5, the lens 7 is restricted from moving in the operation direction D1.

  The insertion portion 25 is inserted into the window portion 18 with the outer surface of the distal end portion in contact with the receiving surface 20 of the window portion 18.

  As shown in FIG. 4, a gap G3 is provided between the left and right width dimension X3 of the distal end portion of the insertion portion 25 and the width dimension X4 of the left and right inner side surfaces constituting the maximum opening end of the tapered surface 19. On the other hand, as shown in FIG. 3, there is a gap between the upper and lower thickness dimension Y3 of the distal end portion of the insertion portion 25 and the gap dimension Y4 of the upper and lower inner surfaces constituting the maximum opening end of the tapered surface 19. A gap G4 is provided on each of the upper and lower sides.

  In the pressing member 4, the lateral gaps G <b> 3 and G <b> 4 between the inner side surface constituting the maximum opening end of the tapered surface 19 and the side surface of the distal end portion of the insertion portion 25 are the side surfaces 5 a to 5 d of the moving member 5. Since the gaps G <b> 1 and G <b> 2 in the lateral direction between the knob 6 and the side plate 16 are set larger, the insertion portion 25 can be prevented from being damaged when the pressing member 4 is assembled.

  Further, a lateral gap between the distal end portion of the insertion portion 25 and the receiving surface 20 of the window portion 18 (which is set to approximately 0 mm in the present embodiment) is between the moving member 5 and the knob 6. It is set smaller than the gaps G1 and G2.

  Hereinafter, a method for assembling the pressing member 4 will be described.

  When assembling the pressing member 4, first, as shown in FIG. 5, the holding portion 22 of the lens 7 is inserted into the holding hole 8 from the distal end side of the moving member 5. As a result, the distal end portions of the leaf spring portions 26 and 27 are elastically deformed inward while being in sliding contact with the convex portions 10 and 11 of the moving member 5, respectively. The tip of the elastic return to the outside. When the leaf springs 26 and 27 are elastically restored in this way, the distal ends of the leaf springs 26 and 27 come into contact with the side surfaces 10a and 11a of the convex portions 10 and 11 and are pulled out even if the lens 7 is to be pulled out. I can't do that. When the holding portion 22 is further inserted to the back, as shown in FIG. 5, the restricting pieces 23 and 24 come into contact with the side surfaces 10b and 11b of the convex portions 10 and 11, and the movement of the holding portion 22 in the inserting direction is restricted. Is done.

  Next, an operation of covering the moving member 5 with the knob 6 from the distal end side of the moving member 5 is performed. Specifically, in this operation, the knob 6 is covered on the tip of the moving member 5 such that the inner surface of the side plate 16 of the knob 6 slides on the side surfaces 5 a to 5 d of the moving member 5. At this time, in this embodiment, the lateral gaps G3 and G4 between the inner surface constituting the maximum opening end of the tapered surface 19 and the side surface of the distal end portion of the insertion portion 25 are the side surfaces 5a to 5 of the moving member 5. Since the lateral gaps G1 and G2 between 5d and the side plate 16 of the knob 6 are set larger than each other, the knob 6 is placed on the moving member 5 so that the side plate 16 and the side surfaces 5a to 5d slide. As a result, the insertion portion 25 of the lens 7 falls within the range of the inner side surface constituting the maximum opening end of the tapered surface 19. Therefore, the insertion portion 25 of the lens 7 is inevitably guided into the window portion 18 in accordance with the operation of placing the knob 6 on the moving member 5.

  As shown in FIG. 4, when the knob 6 is inserted to a preset depth position with respect to the moving member 5, each claw portion 9 of the moving member 5 engages with the locking window 21 of the knob 6. Thus (see FIG. 1), the relative movement of the moving member 5 and the knob 6 in the operation direction D1 is restricted. In this state, the restriction pieces 23 and 24 of the lens 7 are sandwiched between the end surface 17a of the standing portion 17 of the knob 6 and the side surfaces 10b and 11b of the convex portions 10 and 11 of the moving member 5, whereby the lens 7 is also restricted from moving in the operation direction D1.

  As described above, in the pressing member 4, as shown in FIG. 5, the lens 7 and the knob 6 can be sequentially assembled to the moving member 5 that is a common assembling target, and the lens 7 and the knob 6 are commonly assembled. Since the lens 7 can be assembled along the direction D2, workability can be improved as compared with the case where the lens 6 is assembled to the knob 6 in advance and the knob 6 is assembled to the moving member 5.

  Further, in the pressing member 4, as shown in FIG. 6, the insertion position of the lens 7 can be maintained by the urging force of the leaf spring portions 26 and 27, and the knob 6 is covered with the moving member 5 from this state. Since the regulating pieces 23 and 24 can be pushed to the moving member 5 side by the end face (pressing portion) 17a of the knob 6 according to the operation, even if the insertion position of the lens 7 is incomplete, The lens 7 can be inserted into the normal position of the moving member 5 by covering the knob 6 while preventing the drop.

  As described above, according to the embodiment, the surface surrounding the window portion 18 includes the tapered surface 19 that widens toward the moving member 5, so when inserting the insertion portion 25 into the window portion 18, Even if the distal end portion of the insertion portion 25 is displaced laterally from the normal insertion position, the inner side surface is within the range of the inner side surface constituting the maximum opening end of the tapered surface 19. The insertion portion 25 can be guided to the deep portion of the window portion 18 along the line.

  Further, in the present invention, the lateral gaps G3 and G4 between the inner side surface constituting the maximum opening end of the tapered surface 19 and the side surface of the distal end portion of the insertion portion 25 are the side surfaces 5a to 5d of the moving member 5 and the knob. 6 is set to be larger than the lateral gaps G1 and G2 between the side plate 16 and the inner side surface of the side plate 16 of the knob 6 with respect to the side surfaces 5a to 5d of the moving member 5. By covering the knob 6 on the moving member 5, the insertion portion 25 of the lens 7 held by the moving member 5 is necessarily inserted into the window portion 18.

  The insertion portion 25 has an insertion position set in advance with respect to the window portion 18, that is, a lateral gap between the accommodation surface 20 of the window portion 18 and the side surface of the insertion portion 25 has side surfaces 5 a to 5 a of the moving member 5. Insertion is performed up to an insertion position smaller than the lateral gaps G1 and G2 between 5d and the side plate 16 of the knob 6. Therefore, if the tapered surface 19 is not formed as in the prior art, only the gaps G1 and G2 between the side surfaces 5a to 5d of the moving member 5 and the side plate 16 of the knob 6 are used. If it moves to the horizontal direction, it will become possible to guide to the range which cannot insert the insertion part 25, without damaging the insertion part 25 by the guide by the taper surface 19. FIG.

  That is, according to the above-described embodiment, the tapered portion 19 that widens toward the moving member 5 can be guided to a preset insertion position without damaging the insertion portion 25, and the insertion portion 25 at this insertion position. It is possible to achieve both the advantage of ensuring good appearance when the knob 6 is viewed from the surface by reducing the gap between the window portion 18 and the window portion 18.

  Further, even when a procedure for holding the lens 7 on the moving member 5 and covering the moving member 5 with the knob 6 is adopted, the insertion portion 25 hidden behind the knob 6 and invisible. The insertion operation with the window portion 18 can be reliably performed.

  Therefore, according to the above-described embodiment, the knob 6 is attached to the moving member 5 holding the lens 7 without changing the work procedure of inserting the insertion portion 25 of the lens 7 into the window portion 18 in advance. Since the insertion portion 25 can be guided into the window portion 18 along the tapered surface 19 by covering, the damage of the lens 7 (insertion portion 25) can be suppressed while maintaining good workability. .

  Specifically, in the above-described embodiment, the taper surface 19 includes the accommodation surface 20 that extends straight from the inner surface constituting the minimum opening end in the operation direction D1 and is connected to the pressing surface 15a of the top plate 15, and the insertion portion. Reference numeral 25 denotes a length that allows the tip of the window 18 to be accommodated inside the accommodation surface 20 when the window 18 is inserted to a preset insertion position. By comprising in this way, the clearance dimension between the front-end | tip part of the insertion part 25 and the inner surface of the window part 18 is made into the clearance gap between the front-end | tip part of this insertion part 25, and the accommodation surface 20 formed straight. Since it can be set as a dimension, management of the said gap dimension can be performed reliably.

  In the embodiment, the pressing member 4 can be assembled by inserting the lens 7 in the assembly direction D2 with respect to the holding hole 8 of the moving member 5 and covering the knob 6 with the moving member 5 in the assembly direction D2. The assembly direction of the lens 7 and the knob 6 with respect to the moving member 5 can be unified to D2, and workability can be further improved.

  When the insertion position of the holding portion 22 with respect to the holding hole 8 has reached the specific insertion position as in the above-described embodiment, the regulation pieces 23 and 24 and the side surfaces 10b and 11b of the convex portions 10 and 11 come into contact with each other. When the lens 7 is assembled to the moving member 5, the insertion position of the holding portion 22 with respect to the holding hole 8 is set to a specific position by restricting the movement of the holding portion 22 with respect to the moving member 5 in the insertion direction. Since the position can be limited, the operator can be informed that this insertion position is the completion position of the insertion operation of the lens 7, which is different from the case where the operator performs the insertion operation of the lens 7 with concern about the insertion position. The workability can be improved by performing the insertion work uniformly up to the insertion position.

  Furthermore, even when the lens 7 (insertion portion 25) is pressed through the window 18 when the knob 6 is pressed after the moving member 5 and the knob 6 are assembled, the lens 7 is not moved. 5 can be prevented from moving to the back.

  In the state where the insertion position of the holding portion 22 with respect to the holding hole 8 has reached the specific insertion position as in the above-described embodiment, the leaf spring portions 26 and 27 and the side surfaces 10a and 11a of the convex portions 10 and 11 abut. Thus, according to the configuration in which the movement of the holding portion 22 with respect to the moving member 5 is restricted, the weight of the lens 7 is reduced after the lens 7 is attached to the moving member 5 and before the knob 6 is covered. Even when the lens 7 is applied in the direction in which the lens 7 is pulled out from the moving member 5, it is possible to prevent the lens 7 from dropping from the moving member 5.

  Further, as shown in FIG. 6, the leaf spring portions 26 and 27 can be elastically deformed and pressed against the inner surface of the holding hole 8 to maintain the insertion position of the holding portion 22 with respect to the moving member 5. In addition, the knob 6 has a holding portion 22 in which the insertion position is maintained by the biasing force of the leaf spring portions 26 and 27 in the holding hole 8 in accordance with the movement of the moving member 5. Therefore, even when the insertion depth of the lens 7 with respect to the moving member 5 is incomplete, the knob 6 is subsequently put on the moving member 5 and is held by the end face 17a of the knob 6. The part 22 can be inserted into the holding hole 8. Accordingly, after the lens 7 is incompletely inserted into the moving member 5, the weight of the lens 7 is added in the direction in which the lens 7 is pulled out from the moving member 5 before the knob 6 is put on the moving member 5. Even in such a case, the lens 7 is inserted into the movable member 5 to the proper insertion position by covering the knob 6 without performing the separate operation of inserting the lens 7 while preventing the lens 7 from falling off. can do.

  As in the above-described embodiment, the restricting pieces 23 and 24 are sandwiched between the side surfaces 10b and 11b of the convex portions 10 and 11 and the end surface 17a of the knob 6, thereby restricting the movement of the lens 7 in the operation direction D1. With this configuration, since the rattling of the lens 7 in the operation direction D1 can be suppressed after the moving member 5 is covered with the knob 6, the appearance of the light guided from the LED 3 to the insertion portion 25 changes. Can be suppressed.
