The slide part 60 is a protrusion extending along the front-rear direction X. A plurality of slide portions 60 are formed on both side portions in the left-right direction Z of the upper wall portion 58b.

FIG. 11 is a top view of the lower cover 46.
As shown in FIGS. 7, 8, and 11, the lower wall portion 58 c of the lower cover 46 includes a slide guide portion 62 that slides the slide portion 60 that is a part of the upper cover 48 along the slide direction X. A plurality of slide guide portions 62 are provided corresponding to each of the plurality of slide portions 60 on a one-to-one basis. A plurality of slide guide portions 62 are provided on both side portions of the lower cover 46 in the left-right direction Z and a plurality of slide guide portions 62 are provided in the front-rear direction X corresponding to each of the plurality of slide portions 60. FIG. 8 shows a range in the front-rear direction X in which one slide guide portion 62 is provided.

  As shown in FIGS. 7 and 8, the slide guide portion 62 includes a first guide surface 62 a provided below the slide portion 60 and a first guide surface 62 a provided on one side in the left-right direction Z with respect to the slide portion 60. The second guide surface 62b and the third guide surface 62c provided on the upper side with respect to the slide portion 60 are provided. The slide guide portion 62 has a guide groove 62d defined by the first guide surface 62a, the second guide surface 62b, and the third guide surface 62c. The guide groove 62d extends along the front-rear direction X and opens toward one side of the left-right direction Z. The guide grooves 62 d of the separate slide guide portions 62 on both sides in the left-right direction Z of the lower cover 46 are opened in directions away from the opposite sides of the left-right direction Z.

  The first guide surface 62a is configured by the upper surface of the lower wall portion 58c. The first guide surface 62a is formed to be continuous with the first guide surface 62a of another slide guide portion 62 adjacent in the front-rear direction X. The second guide surface 62 b is configured by a lateral side surface of a vertical wall portion 58 e that stands from the lower wall portion 58 c of the lower cover 46. The second guide surface 62b is formed to be continuous with the second guide surface 62b of another slide guide portion 62 adjacent in the front-rear direction X. The third guide surface 62c is configured by the lower surface of the horizontal wall portion 58f that protrudes from the front end portion of the vertical wall portion 58e toward one side in the left-right direction Z. The third guide surface 62c is formed to have a shorter front-rear dimension than the first guide surface 62a and the second guide surface 62b.

  The slide portion 60 of the upper cover 48 is disposed in the guide groove 62 d of the slide guide portion 62 of the lower cover 46. The slide part 60 slides along the guide groove 62 d of the slide guide part 62. Accordingly, the upper cover 48 is provided to be slidable along the sliding direction X (front-rear direction) with respect to the lower cover 46.

  As shown in FIG. 8, the case where the slide part 60 is arrange | positioned in the guide groove 62d of the slide guide part 62 is considered. In this case, if the upper cover 48 is to be displaced upward with respect to the lower cover 46, the upper cover 48 cannot be separated from the lower cover 46 due to the contact between the third guide surface 62 c of the slide guide portion 62 and the slide portion 60. Hereinafter, a position where the lower cover 46 and the upper cover 48 cannot be separated in a direction different from the slide direction X (in this example, the vertical direction Y) is referred to as an unseparable position.

12 is a view showing a state in which the lower cover 46 and the upper cover 48 are relatively moved in the slide direction X from the positional relationship of FIG.
As shown in FIG. 12, a case is considered in which the slide portion 60 is not disposed in the guide groove 62 d of the slide guide portion 62 and the slide portion 60 is in contact with the first guide surface 62 a of the slide guide portion 62. In this case, when the upper cover 48 is to be displaced upward with respect to the lower cover 46, the third guide surface 62 c of the slide guide portion 62 and the slide portion 60 do not come into contact with each other and can be separated from the lower cover 46. . Hereinafter, a position where the lower cover 46 and the upper cover 48 can be separated in a direction (vertical direction Y) different from the slide direction X is referred to as a separable position.

  As described above, the upper cover 48 can move between the separable position and the non-separable position by sliding with respect to the lower cover 46. It can be said that the upper cover 48 and the lower cover 46 are configured to be relatively movable between a separable position and a non-separable position by sliding relative to each other.

  As shown in FIGS. 6, 8, and 9, the lower cover 46 includes a first stopper portion 46 a that is disposed on the front side with respect to the rear wall portion 58 d of the upper cover 48. The first stopper portion 46 a is a convex portion that protrudes upward from the lower wall portion 58 c of the lower cover 46. The first stopper portion 46 a defines the front end position of the sliding range of the upper cover 48 relative to the lower cover 46 by engaging with the rear wall portion 58 d of the upper cover 48. When the upper cover 48 is at least at the front end position of the slide range, the lower cover 46 and the upper cover 48 are in a non-separable position.

  As shown in FIGS. 9 and 12, the lower cover 46 includes a second stopper portion 46 b disposed on the rear side with respect to the rear wall portion 58 d of the upper cover 48. The second stopper portion 46 b is a convex portion that protrudes upward from a location facing the upper side of the lower cover 46 on the rear side of the cavity portion 58 of the housing 42. The second stopper portion 46 b defines the rear end position of the sliding range of the upper cover 48 relative to the lower cover 46 by engaging with the rear wall portion 58 d of the upper cover 48. When the upper cover 48 is at least at the rear end position of the slide range, the lower cover 46 and the upper cover 48 are in a separable position. The second stopper portion 46b is also a first holding wall portion 74 described later.

The assembly procedure of the housing 42 will be described.
First, the separated lower cover 46 and upper cover 48 are moved to at least a separable position by relative movement in at least the vertical direction Y (see FIG. 12). Thereafter, the covers 42 and 48 are slid in the sliding direction X and moved to the position where they cannot be separated, thereby completing the assembly of the housing 42 (see FIG. 8). Thereby, unless the covers 46 and 48 are moved from the non-separable position to the separable position, a temporarily fixed state where the two cannot be separated can be easily created.

Next, a procedure for disassembling the housing 42 will be described.
First, the respective covers 46 and 48 are moved from the non-separable position to the separable position by sliding in the slide direction X (see FIG. 12). Thereafter, the respective covers 46 and 48 are moved relative to each other in the vertical direction Y to be separated, whereby the disassembly of the housing 42 is completed.

  As described above, according to the head holder 36 of the present embodiment, the assembly work of the housing 42 is completed only by moving the covers 46 and 48 in order. Therefore, the housing 42 can be easily assembled as compared with the case where screws are used for assembling the housing 42.

  Further, the disassembly work of the housing 42 is completed only by moving the covers 46 and 48 in order. Accordingly, the housing 42 can be easily disassembled and the housing 42 can be easily reassembled as compared with the case where screws are used for assembling the housing 42.

  Further, when the snap-fit elastic claws are used for assembling the housing 42, when the housing 42 is disassembled, it is necessary to move the elastic claws to release the engagement with other members. The elastic claw is normally engaged with another member at a recessed portion where it is difficult for the fingertip to reach, and a tool is required to release the engagement of the elastic claw. In this respect, according to the present embodiment, since no tool is required for disassembling the housing 42, the housing 42 can be easily disassembled and the housing 42 can be easily reassembled as compared with the case where elastic claws are used for assembling the housing 42. It becomes.

  Further, since no screws or elastic claws are required for assembling the housing 42, it is possible to prevent the wear of the housing 42 due to attachment / detachment of the screws and deterioration due to repeated use of the elastic claws, and it is easy to improve the durability of the housing 42. .

  The lower cover 46 and the upper cover 48 are configured to move relative to each other between the separable position and the non-separable position by sliding with each other. Therefore, compared with the case where an elastic claw is used for assembling the housing 42, it is easy to secure a contact area between the lower cover 46 and the upper cover 48, and the fixing degree between the lower cover 46 and the upper cover 48 can be increased.

  Further, since the slide guide portions 62 are provided on both sides in the left-right direction of the lower cover 46, it becomes easy to suppress rattling around the X axis in the sliding direction between the lower cover 46 and the upper cover 48. The degree of fixation with the upper cover 48 can be increased.

  Further, if there is only one slide guide portion 62 in the slide direction X, if an attempt is made to increase the contact area between the slide guide portion 62 and the slide portion 60 in the slide direction X, from the separable position to the non-separable position. The slide distance becomes longer. In this regard, since a plurality of the slide guide portions 62 of the present embodiment are provided in the slide direction X, the slide guide portions 62 and It becomes easy to ensure the contact area in the sliding direction X with the slide part 60. Therefore, by shortening the sliding distance between the lower cover 46 and the upper cover 48, the workability at the time of assembling and reassembling is improved, and the contact area between the lower cover 46 and the upper cover 48 is ensured to ensure the lower cover 46 and the upper cover 48. The degree of fixation with 48 can be increased.

  As will be described later, the head holder 36 has a structure including the sensor member 20 and the display member 22 to which the first wiring 50 and the second wiring 52 drawn from the cavity 58 of the housing 42 are connected. In the case of such a structure, when the housing 42 is assembled, the wirings 50 and 52 may be caught between the lower cover 46 and the upper cover 48.

  If a screw is used for assembling the housing 42, there is a case where the screw can be fastened without noticing that the wires 50 and 52 between the lower cover 46 and the upper cover 48 are caught. In addition, when an elastic claw is used for assembling the housing 42, even if the wires 50 and 52 are caught between the lower cover 46 and the upper cover 48, the elastic claw is engaged with another member without noticing that. There are cases that can be made.

  In this regard, according to the head holder 36 of the present embodiment, when the wirings 50 and 52 are caught between the lower cover 46 and the upper cover 48, when these are slid from the separable position to the non-separable position. Since the wirings 50 and 52 become resistances, it is easy to notice the biting of the wirings 50 and 52. Therefore, it is possible to prevent the housing 42 from being assembled by mistake while the wirings 50 and 52 are engaged between the lower cover 46 and the upper cover 48.

  This embodiment has the following features in terms of an attachment structure 64 for attaching the head holder 36 to the base frame 32. As shown in FIGS. 3 and 5, the rear end portion of the lower cover 46 is inserted into the insertion hole 32 b of the base frame 32. An elastic claw 42 c is formed in the hose insertion portion 42 a of the lower cover 46. When the rear end of the head holder 36 is inserted into the insertion hole 32b, the elastic claw 42c is elastically deformable and returns to a position where it can engage with a part of the insertion hole 32b. The lower cover 46 is prevented from being removed from the insertion hole 32b by engagement of a part of the insertion hole 32b with the elastic claw 42c.

13 is a cross-sectional view taken along the line CC of FIG. In this figure, the water supply hose 40 and the like are omitted.
As shown in FIGS. 8, 11, and 13, a sandwiched portion 46 c is provided at a position facing the upper side at the rear end portion of the lower cover 46. A clip hole 32e communicating with the insertion hole 32b is formed in the base frame 32, and a clip 66 is inserted into the clip hole 32e. The clip 66 has a pair of elastic arms 66 a arranged so as to sandwich the sandwiched portion 46 c of the lower cover 46. The pair of elastic arms 66a is in a state of being elastically deformed so as to expand in diameter, and sandwiches the sandwiched portion 46c of the lower cover 46 by a restoring force. Thereby, the clip 66 is detachably attached to the lower cover 46.

The operational effects of the head holder 36 will be described.
The head holder 36 includes a pressing member 44 that is held in a state in which the first wiring 50 is sandwiched between the inner surface of the cavity 58 of the housing 42. Therefore, when the housing 42 is assembled, the first wiring 50 can be prevented from being caught between the lower cover 46 and the upper cover 48 by suppressing the displacement of the first wiring 50 by the pressing member 44.

  Further, since the first wiring 50 can be prevented from being bitten, when the housing 42 is assembled, the position adjustment work for reducing the amount of displacement of the first wiring 50 is not required, and the assembling property of the housing 42 is improved.

  Further, when the housing 42 is assembled, the pressing member 44 prevents the first wiring 50 from being displaced, so that interference with other members such as the display member 22 can be prevented, and the assemblability of the head holder 36 is improved.

  Further, the pressing member 44 fixes the sensor member 20 to the housing 42 by contacting the sensor member 20. Therefore, the pressing member 44 can have a function of fixing the sensor member 20, and other members for fixing the sensor member 20 are not necessary, and the number of parts of the head holder 36 can be suppressed. Further, the sensor member 20 can be fixed to the lower cover 46 together with the pressing member 44 by simply attaching the pressing member 44 to the lower cover 46, and the head holder 36 can be easily assembled.

  The display member 22 is fixed in a state where it is placed on the pressing wall portion 44 a of the pressing member 44. Therefore, the space on the first wiring 50 of the sensor member 20 can be used as an arrangement space for the display member 22, and the hollow portion 58 of the housing 42 can be easily miniaturized rather than disposing the display member 22 in other places.

  When the display member 22 is placed directly on the first wiring 50 when the display member 22 is disposed on the first wiring 50 of the sensor member 20, the first wiring 50 is usually circular, Since one wiring 50 is easily displaced, the support state of the display member 22 becomes unstable. In this regard, according to the present embodiment, the display member 22 is fixed in a state where it is placed on the pressing wall portion 44a of the pressing member 44, and therefore the display member is more directly placed than on the first wiring 50. The support state of 22 is stabilized, and the fixing degree of the display member 22 can be increased.

  Further, when the housing 42 is assembled, the display member 22 attached to the upper cover 48 can be slid on the pressing wall portion 44 a of the pressing member 44. Therefore, the display member 22 can be smoothly slid rather than being slid on the first wiring 50 that is easily displaced, and the assembly of the housing 42 is improved. In particular, the wiring usually has a skin layer made of a soft resin or the like. Therefore. The flat surface of the hard pressing member 44 can slide the display member 22 more smoothly than the soft first wiring 50, and the assembly of the housing 42 is also improved from this point.

  The pressing member 44 has a pair of positioning portions 44 e that position the display member 22 in the left-right direction Z by contact with the display member 22. Therefore, the display member 22 can be positioned in the left-right direction Z with respect to the pressing member 44 and the lower cover 46 only by arranging the display member 22 between the pair of positioning portions 44e. In addition, it is possible to easily prevent displacement of the upper cover 48 in the left-right direction Z.

  Further, the first wiring 50 and the second wiring 52 are arranged in a separated state in the cavity 58 of the housing 42. Therefore, in maintenance and replacement of the sensor member 20 and the display member 22, it becomes easy to handle a single member without unwinding the first wiring 50 and the second wiring 52, and good workability can be obtained.

  The first press-fit portion 44b of the pressing member 44 is detachably attached to the lower cover 46 by being press-fitted into the first press-fit portion 58i of the lower cover 46. Accordingly, the pressing member 44 can be easily attached to and detached from the lower cover 46, and the assembly and reassembly of the head holder 36 can be simplified.

  The lower cover 46 and the upper cover 48 are configured so that the upper cover 48 can slide to the front side (first side) with respect to the lower cover 46 as described above when the housing 42 is assembled. Here, the pair of positioning portions 44 e of the pressing member 44 are provided on both sides in the left-right direction Z orthogonal to the front-rear direction X, which is the sliding direction of the upper cover 48. Therefore, the display member 22 can be disposed between the pair of positioning portions 44 e of the pressing member 44 by simply sliding the upper cover 48 forward with respect to the lower cover 46, and the left and right directions of the upper cover 48 with respect to the lower cover 46. The fixing degree at Z can be easily increased. From the viewpoint of obtaining good assemblability, a large clearance in the left-right direction Z for allowing smooth sliding between the upper cover 48 and the lower cover 46 may be secured. Even in this case, there is a great advantage in that the fixing degree in the left-right direction Z can be increased by the pair of positioning portions 44e.

  Further, as shown in FIG. 11, a drain hole 58m is formed in the lower wall portion 58c of the cavity 58 of the head holder 36. A plurality of drain holes 58m are formed side by side in the left-right direction Z in a portion of the lower wall portion 58c near the front wall portion 58a. Specifically, as shown in FIG. 3, when the head holder 36 is attached to the base frame 32, the drain hole 58m is a part of the wall portion of the cavity portion 58 on the vertical lower side (in front of the lower wall portion 58c). (A part near the wall 58a). Accordingly, even when water enters the cavity 58 of the head holder 36, the water can be discharged to the outside through the drain hole 58m of the head holder 36.
