Such a bathing apparatus is disclosed, for example, in Patent Document 1. 【0003】 In Patent Document 1, the bather is placed on the transfer device, and the transfer device is connected to the bathtub. Then, with the bather placed on the transfer device, the bather is put into the bathtub. 【Prior Art Documents】 【Patent Documents】 【0004】 [[ID=2及]]【Patent Document 1】 Japanese Patent Application Laid-Open No. 2002-186656 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 In Patent Document 1, if there is a misalignment in the transfer device connected to the bathtub, the bather cannot be put into the bathtub. Therefore, in Patent Document 1, a sensor for detecting that the transfer device is properly connected to the bathtub is provided, and based on the output of the sensor, it is determined whether or not the bather placed on the transfer device can take a bath. 【0006】 However, in Patent Document 1, in order to suppress misalignment, malfunction, and failure of the sensor, it is necessary to periodically adjust the sensor. Further, when using a sensor, it is necessary to secure an installation location for the sensor and prepare mounting brackets for the sensor, which complicates the structure. 【0007】 The present invention was made to solve the above problems, and aims to provide a bathing device that can suppress misalignment of transport equipment connected to a bathtub with a simple configuration. [Means for solving the problem] 【0008】 To achieve the above objective, a bathing apparatus according to one aspect of the present invention comprises a bathtub having a bottom portion that constitutes the bottom of the bathing space and side portions that surround the bathing space from the sides, and a transport device that places a bather into the bathing space while the bather is seated on it. The bathtub is positioned at a vertical distance from the floor. The transport device comprises a base member to which wheels that make contact with the floor are attached. By inserting the base member below the bathtub and positioning it in a predetermined position, it is possible to place a bather riding on the transport device into the bathing space. The apparatus further comprises a first guide and a second guide positioned below the bathtub to guide the base member to a predetermined position. The base member comprises a first frame and a second frame extending in the front-rear direction and positioned at a distance from each other in the left-right direction, a rear frame extending in the left-right direction to which the first frame and the second frame are connected, a first pressing member positioned at the connection portion between the first frame and the rear frame, and a second pressing member positioned at the connection portion between the second frame and the rear frame. When the first pressing member is pressed against the first guide, and the second pressing member is pressed against the second guide, the base member is positioned in a predetermined location. [Effects of the Invention] 【0009】 In the configuration of the present invention, misalignment of the transport equipment connected to the bathtub can be suppressed with a simple structure.

BEST MODE FOR CARRYING OUT THE INVENTION 【0011】 Hereinafter, referring to FIGS. 1 to FIGS., the bathing apparatus 100 according to the embodiment and its modified examples will be described. In the bathing apparatus 100, the person requiring assistance becomes the bather. That is, the bathing apparatus 100 is operated by the caregiver. In the drawings referred to in the following description, the bather (that is, the person requiring assistance) and the caregiver are not shown. 【0012】 <1. Overall Configuration> First, referring to FIGS. 1 to FIGS., the overall configuration of the bathing apparatus 100 will be described. 【0013】 The bathing device 100 comprises a bathtub 1 and a transport device 2. The bathtub 1 is installed on a flat floor surface FL. The transport device 2 moves while in contact with the floor surface FL. Hereinafter, the direction perpendicular to the floor surface FL is defined as the up and down direction. Furthermore, the side on which the bathtub 1 is installed relative to the floor surface FL is defined as up, and the opposite side is defined as down. 【0014】 Bathtub 1 has a bathing space BS into which a bather enters. When viewed from above, the bathing space BS is roughly rectangular in shape, elongated in one direction. The bathing device 100 is equipped with a shower device 1000. For example, a person requiring assistance can spray water from the shower device 1000 onto the bather. It is also possible to fill the bathing space BS with water. 【0015】 Bathtub 1 has a bottom 11 and side sections 12. The bottom 11 constitutes the bottom of the bathing space BS. That is, the space above the bottom 11 becomes the bathing space BS. The side sections 12 are erected above the bottom 11. The side sections 12 surround the bathing space BS from the sides. Thus, the space enclosed by the bottom 11 and the side sections 12 becomes the bathing space BS. The top of the bathing space BS is open. 【0016】 The bottom portion 11 is positioned at a vertical distance from the floor surface FL. In other words, the bottom portion 11 has a lower surface (which is the surface opposite to the bottom surface of the bottom portion 11) at a vertical distance from the floor surface FL. To put it another way, the bathtub 1 is positioned at a vertical distance from the floor surface FL. The vertical distance between the floor surface FL and the bottom portion 11 is set to a size that allows the base member 3, which will be described later, to be inserted into that distance. 【0017】 To provide a vertical gap between the floor surface FL and the bottom 11, the bathing device 100 is equipped with a base frame 10. The base frame 10 is positioned below the bottom 11. The base frame 10 is attached to the underside of the bottom 11. In other words, the bathtub 1 is placed on the base frame 10. 【0018】 The base frame 10 has multiple legs 101. Each leg 101 is fixed to the main body of the base frame 10, extends downward from the main body of the base frame 10, and makes contact with the floor surface FL. As a result, the bottom 11 is raised relative to the floor surface FL. In other words, a gap is created between the floor surface FL and the bottom 11 in the vertical direction. 【0019】 The side section 12 encloses the bathing space BS seamlessly from the side. When viewed from above, the side section 12 is annular and continuous in the circumferential direction. The bottom section 11 and the side section 12 are integrally molded; that is, the bottom section 11 and the side section 12 are the same component. However, the bathtub cover CV, which will be described later, is detachable from the side section 12. 【0020】 Further details will be provided later, but the bather is placed on a stretcher ST. The bather lies down on the stretcher ST. Then, while still on the stretcher ST, the bather is placed into the bathing space BS from above the bathtub 1. This eliminates the need to use a door on part of the side 12 and open part of the bathing space BS to the side. 【0021】 The upper edge 12E of the side section 12 seamlessly surrounds the bathing space BS when viewed from above. The upper edge 12E is a continuous ring-shaped body that surrounds the bathing space BS when viewed from above. The side section 12 includes the bathtub cover CV. The bathtub cover CV is divided into four sections. The bathtub cover CV constitutes the exterior of the side section 12. 【0022】 Transport device 2 transports bathers. Transport device 2 is detachable from bathtub 1 and can move independently with bathers on board. By using transport device 2, bathers can be transported from a location far from bathtub 1 to its installation location. Then, by connecting transport device 2 to bathtub 1, bathers can be placed into the bathing space BS while still on transport device 2. 【0023】 The transport device 2 is equipped with wheels W that make contact with the floor surface FL. When the transport device 2 is pushed or pulled by its operator (i.e., caregiver), the wheels W rotate and the transport device 2 moves. 【0024】 The transport device 2 includes a base member 3. Casters are attached to the base member 3. Wheels W are components of the casters. That is, the wheels W are rotatably attached to the base member 3. There are four wheels W installed. However, the number of wheels W installed is not particularly limited and can be arbitrarily changed depending on the size and shape of the base member 3. 【0025】 The transport device 2 is connected to the bathtub 1 when the base member 3 is inserted below the bathtub 1 and positioned at a predetermined location below the bathtub 1. In other words, when the base member 3 is positioned at the predetermined location, the transport device 2 is positioned at a bathing position that allows a bather to enter the bath. When connecting to the bathtub 1, the transport device 2 is inserted below the bathtub 1 from the longitudinal side of the side 12 of the bathtub 1. This allows the base member 3 to be positioned at the predetermined location below the bathtub 1. 【0026】 An operating pedal PD is installed on the base member 3. The operating pedal PD is connected to one of the wheels W. When the operating pedal PD is pressed down while the base member 3 is in a predetermined position, the wheel W connected to the operating pedal PD stops rotating. This allows the base member 3 to be held in the predetermined position. 【0027】 The front-to-back and left-to-right directions of the transport device 2 are defined relative to the operator of the transport device 2. When moving the base member 3 to a predetermined position, the operator faces forward and pushes the transport device 2 forward. Then, with the base member 3 facing forward, it is inserted under the bathtub 1. That is, the side the operator faces is the front of the transport device 2, and the opposite side is the rear of the transport device 2. Also, the operator's left hand side is the left side of the transport device 2, and the operator's right hand side is the right side of the transport device 2. 【0028】 The base member 3 has a rear frame 30. The base member 3 also has a first frame 31 and a second frame 32. The rear frame 30, the first frame 31, and the second frame 32 are each roughly rectangular tubular metal frames. The base member 3 is composed of a combination of the rear frame 30, the first frame 31, and the second frame 32. 【0029】 The rear frame 30 extends in the left-right direction. The rear frame 30 is the frame located at the rear of the base member 3. Two wheels W are attached to the rear frame 30. Of the two wheels W attached to the rear frame 30, one wheel W is located at the left end of the rear frame 30, and the other wheel W is located at the right end of the rear frame 30. 【0030】 The first frame 31 and the second frame 32 each extend in the front-rear direction. The first frame 31 and the second frame 32 are spaced apart from each other in the left-right direction. The first frame 31 is located on the left side, and the second frame 32 is located on the right side. The first frame 31 and the second frame 32 each extend forward from the rear frame 30. That is, the rear ends of the first frame 31 and the second frame 32 are connected to the rear frame 30. The first frame 31 and the second frame 32 may be welded to the rear frame 30 or fastened with fastening members. 【0031】 One wheel W is attached to each of the first frame 31 and the second frame 32. The wheel W attached to the first frame 31 is positioned at the front end of the first frame 31. The wheel W attached to the second frame 32 is positioned at the front end of the second frame 32. 【0032】 Furthermore, one rotating body RB, such as a roller, is rotatably mounted on the upper surface of the front end of each of the first frame 31 and the second frame 32. Each rotating body RB rotates around an axis that extends in the vertical direction. 【0033】 The conveying device 2 is equipped with a support column 4. The support column 4 is made of metal and is roughly rectangular in shape. The support column 4 is fixed to the base member 3. The support column 4 is erected upwards. Inside the support column 4 are shafts and other components of a lifting mechanism (not shown), which will be described later. 【0034】 To fix the support column 4 to the base member 3, the conveying equipment 2 is equipped with a fixing member 40. The fixing member 40 is made of sheet metal. The fixing member 40 is fixed to the rear frame 30. The fixing member 40 may be welded to the rear frame 30 or fastened to the rear frame 30 with a fastening member. 【0035】 The fixing member 40 is positioned in the center of the rear frame 30 in the left-right direction and protrudes further rearward than the rear frame 30. The support column 4 is erected upward from the portion of the fixing member 40 that protrudes further rearward than the rear frame 30. In other words, the support column 4 is fixed to the base member 3 via the fixing member 40 and erected upward. The support column 4 may be welded to the fixing member 40 or fastened to the fixing member 40 with a fastening member. 【0036】 The transport device 2 includes a support member 5. The transport device 2 also includes a lifting mechanism (not shown) composed of a motor or the like. The support member 5 is attached to the support column 4. The support member 5 moves vertically along the support column 4 due to the driving force from the lifting mechanism. 【0037】 The support member 5 comprises a main body 51 and an arm 52. The main body 51 is mounted on the support column 4 so as to be movable in the vertical direction. A motor and other components of the lifting mechanism are arranged inside the main body 51. The arm 52 is fixed to the main body 51. A person to be bathed is placed on the arm 52. Specifically, a stretcher ST on which the person to be bathed is fixed to the arm 52. 【0038】 The arm 52 has a first arm 521 extending downward from the main body 51 and a second arm 522 extending forward from the lower end of the first arm 521. The stretcher ST is fixed to the second arm 522 with a fastening member. The stretcher ST may be detachable from the second arm 522. 【0039】 By inserting the base member 3 below the bathtub 1 and arranging it at a predetermined position, it becomes possible to place the bather in the bathing space BS while the bather is on the arm 52 (i.e., the stretcher ST). Specifically, by inserting the base member 3 below the bathtub 1 and arranging it at a predetermined position, a part of the support member 5 gets over the side part 12, and the arm 52 fixed to that part is arranged above the bathing space BS. In that state, by lowering the support member 5, the second arm 522 to which the stretcher ST of the arm 52 is fixed can be placed in the bathing space BS. That is, the bather can be placed in the bathing space BS. 【0040】 As a modification, the bathtub 1 may be movable in the vertical direction. In this case, with the stretcher ST arranged above the bathing space BS, by raising the bathtub 1, the stretcher ST (i.e., the bather) can be placed in the bathing space BS. 【0041】 For example, when the base member 3 is inserted below the bathtub 1 and moved to a predetermined position, the actuator of a sensor (e.g., a microswitch) is pressed, and a predetermined signal is output from the sensor. And at this time, an alarm sound is output from a speaker (not shown). Thereby, it can be notified to the assistant that the connection between the bathtub 1 and the conveying device 2 is completed, that is, that the base member 3 is arranged at the predetermined position and it has become possible to place the bather in the bathing space BS. 【0042】 Note that the above sensor may be arranged in the bathtub 1 or in the conveying device 2. The above speaker may be arranged in the bathtub 1 or in the conveying device 2. 【0043】 <2. Connection position> Next, the connection position of the transport device 2 to the bathtub 1 will be explained with reference to Figures 6 to 10. Hereinafter, when viewed from above, the area on the bathing space BS side of the outer edge of the side portion 12 is defined as the inside of the bathtub 1, and the area on the opposite side of the outer edge of the side portion 12 from the bathing space BS side is defined as the outside of the bathtub 1. In other words, when viewed from above, the area that overlaps with the bathtub 1 is the inside of the bathtub 1, and the area that does not overlap with the bathtub 1 is the outside of the bathtub 1. In Figures 6 and 9, a dot pattern is applied to the upper edge 12E of the side portion 12 of the bathtub 1. In Figures 7 and 10, the outer edge of the side portion 12 when the bathtub 1 is viewed from above is shown with a dashed line. 【0044】 <2-1. Embodiments> When connecting the transport device 2 to the bathtub 1, the transport device 2 is pushed from behind with the front ends of the first frame 31 and the second frame 32 facing forward. The transport device 2 is inserted below the bathtub 1 with the front ends of the first frame 31 and the second frame 32 facing forward (see Figure 6). This allows the base member 3 to be positioned in a predetermined location (see Figure 7). In other words, the transport device 2 can be connected to the bathtub 1. 【0045】 Here, as shown in Figure 7, when the base member 3 is positioned in the predetermined location, when viewed from above, the entire base member 3 is positioned inward from the outer edge of the side portion 12. As a result, when the base member 3 is positioned in the predetermined location, when viewed from above, the base member 3 does not protrude outward from the outer edge of the side portion 12. The caster with wheels W is of the swivel type, and the direction of the wheels W can be changed. By changing the direction of the wheels W, they can be positioned inward from the outer edge of the side portion 12 when viewed from above. 【0046】 Furthermore, when the base member 3 is positioned in its predetermined location, a portion of the fixing member 40 is positioned outside the outer edge of the side portion 12 when viewed from above. The support column 4 is erected from the portion of the fixing member 40 that is positioned outside the outer edge of the side portion 12 when viewed from above. As a result, when the base member 3 is positioned in its predetermined location, the support column 4 is positioned outside the outer edge of the side portion 12 when viewed from above. 【0047】 As shown in Figure 8, when the base member 3 is positioned in the predetermined location, a portion 510 of the support member 5 extends over the side portion 12. That is, when the base member 3 is positioned in the predetermined location, a portion 510 of the support member 5 is positioned above the bathing space BS. An arm 52 is fixed to a portion 510 of the support member 5. The support member 5 has a portion 510 of it which serves as an arm fixing portion (hereinafter referred to as the arm fixing portion 510). 【0048】 The first arm 521 is fixed to the arm fixing part 510 and extends downward from the arm fixing part 510. The second arm 522 extends forward from the lower end of the first arm 521. Therefore, after positioning the base member 3 in a predetermined location, lowering the support member 5 causes the second arm 522 of the arms 52 to move into the bathing space BS. This allows a bather on a stretcher ST fixed to the second arm 522 to enter the bathing space BS. 【0049】 Furthermore, a roller 520 that rotates around an axis extending in the left-right direction is attached to the rear end of the lower part of the first arm 521. In other words, a roller 520 that rotates around an axis extending in the left-right direction is attached to the rear side of the second arm 522. When the second arm 522 enters the bathing space BS, the roller 520 comes into contact with the inner surface of the side part 12, and in that state, the second arm 522 moves in the vertical direction. 【0050】 In this embodiment, when bathing assistance is provided to a bather (i.e., a person requiring assistance) using the bathtub 1 and transport device 2, the entire base member 3 of the transport device 2, which is located at the caregiver's feet, is inserted below the bathtub 1. This eliminates obstacles in the space at the caregiver's feet, making it easier for them to move. Specifically, as shown in Figure 7, a wide space SP is created where the caregiver can step in, as viewed from above. That is, a wide space SP including the area around the support column 4 becomes the assistance space, as viewed from above. As a result, even if the bather is brought into the bathing space BS of the bathtub 1 from above, the caregiver's work efficiency is improved. 【0051】 In this embodiment, since the bather is entered into the bathing space BS of the bathtub 1 from above, a door for opening the bathing space BS to the side is not installed in the bathtub 1. This helps to suppress an increase in the number of parts and structural complexity of the bathtub 1. 【0052】 Furthermore, in this embodiment, when the base member 3 is positioned in a predetermined location, the support column 4 is positioned outside the outer edge of the side portion 12 when viewed from above. As a result, even when the entire base member 3 is inserted below the bathtub 1, it is not necessary to provide any relief portion for the support column 4 or the like in the bathtub 1. 【0053】 Furthermore, in this embodiment, since the fixing member 40 of the support column 4 is positioned on the rear side of the base member 3, the entire base member 3 can be easily inserted below the bathtub 1. With the entire base member 3 inserted below the bathtub 1, a bather can be placed in the bathing space BS while standing on the arm 52 of the support member 5 attached to the support column 4. 【0054】 <2-2. Modified Connection Positions> In the modified configuration, similar to the above embodiment, the transport device 2 is inserted below the bathtub 1 with the front ends of the first frame 31 and the second frame 32 facing forward (see Figure 9). This allows the base member 3 to be positioned in a predetermined location (see Figure 10). In other words, the transport device 2 can be connected to the bathtub 1. 【0055】 In this modified version, the side portion 12 of the bathtub 1 has a recess 20 that, when viewed from above, is recessed inward from its outer edge. Furthermore, the bathtub cover CV has a recess formed that reflects the shape of the recess 20. That is, the bathtub cover CV has a groove that extends in the vertical direction. 【0056】 In the modified example, the column 4 of the transfer device 2 stands upright upward from the upper surface of the base member 3. Specifically, the column 4 stands upright upward from the upper surface of the rear frame 30. For example, the column 4 may be directly fixed to the rear frame 30. Also, although not shown, a member corresponding to the fixing member 40 may be fixed to the upper surface of the rear frame 30, and the column 4 may stand upright upward from the member. 【0057】 In the modified example, in a state where the base member 3 is disposed at a predetermined position, at least a part of the column 4 is disposed inside the outer edge of the side portion 12 when viewed from above. Specifically, in a state where the base member 3 is disposed at a predetermined position, the column 4 is disposed in the concave portion 20 when viewed from above. That is, in a state where the base member 3 is disposed at a predetermined position, the column 4 is embedded in the side portion 12 (see FIG. 10). 【0058】 In the modified example, in addition to the base member 3, the column 4 is disposed inside the outer edge of the side portion 12. Thereby, a wider space SP into which the caregiver can step can be secured. As a result, the workability of the caregiver is further improved. Also, by providing the concave portion 20 in the side portion 12, the column 4 can be easily disposed inside the outer edge of the side portion 12. 【0059】 <3. Position Adjustment Mechanism> Next, referring to FIGS. 11 to 18, the position adjustment mechanism of the transfer device 2 connected to the bathtub 1 will be described. 【0060】 <3-1. Embodiment> As shown in FIG. 11, the bathing apparatus 100 includes a first guide 110 and a second guide 120. The first guide 110 and the second guide 120 are each made of sheet metal. The first guide 110 and the second guide 120 guide the transfer device 2 to the bathing position. That is, the first guide 110 and the second guide 120 guide the base member 3 to a predetermined position. 【0061】 The first guide 110 and the second guide 120 are each positioned below the bathtub 1. Specifically, the first guide 110 and the second guide 120 are each attached to the base frame 10. The base frame 10 is attached to the underside of the bottom 11. That is, the first guide 110 and the second guide 120 are each attached to the underside of the bottom 11. The first guide 110 and the second guide 120 are each positioned so that their plate thickness direction is in the horizontal direction perpendicular to the vertical direction. 【0062】 The first guide 110 and the second guide 120 each extend in the front-to-back direction perpendicular to the vertical direction, and are spaced apart from each other in the left-to-right direction perpendicular to both the vertical and front-to-back directions. The front-to-back direction is the shorter direction when viewed from above the bathing space BS. The left-to-right direction is the longer direction when viewed from above the bathing space BS. That is, the shorter direction when viewed from above the bathing space BS is defined as the front-to-back direction of the bathtub 1, and the longer direction when viewed from above or below the bathing space BS is defined as the left-to-right direction of the bathtub 1. 【0063】 A first centering portion 111 is provided at the front-rear end of the first guide 110. A second centering portion 121 is provided at the front-rear end of the second guide 120. The first centering portion 111 and the second centering portion 121 will be described in detail later. 【0064】 As shown in Figure 12, the conveying device 2 includes a first pressing member 311 and a second pressing member 321. The first pressing member 311 and the second pressing member 321 are members for centering the conveying device 2 connected to the bathtub 1. Although not particularly limited, the first pressing member 311 and the second pressing member 321 are each made of hard rubber. 【0065】 The first pressing member 311 and the second pressing member 321 are each formed to be right-angled triangles when viewed from above. The first pressing member 311 is positioned in the corner formed between the first frame 31 and the rear frame 30 when viewed from above. In other words, the first pressing member 311 is positioned at the connection point between the first frame 31 and the rear frame 30. The second pressing member 321 is positioned in the corner formed between the second frame 32 and the rear frame 30 when viewed from above. In other words, the second pressing member 321 is positioned at the connection point between the second frame 32 and the rear frame 30. 【0066】 The first pressing member 311 is positioned on the left side of the first frame 31. The second pressing member 321 is positioned on the right side of the second frame 32. The left side of the first frame 31 is opposite to the side of the second frame 32, and the right side of the second frame 32 is opposite to the side of the first frame 31. The right side of the first frame 31 is the side of the second frame 32, and the left side of the second frame 32 is the side of the first frame 31. 【0067】 Furthermore, of the two sides of the first pressing member 311 that form a right angle when viewed from above, one side is in contact with the first frame 31 and the other side is in contact with the rear frame 30. Of the two sides of the second pressing member 321 that form a right angle when viewed from above, one side is in contact with the second frame 32 and the other side is in contact with the rear frame 30. 【0068】 As a result, the first pressing member 311 has a first inclined surface 311S that is inclined with respect to the front-rear and left-right directions when viewed from the vertical direction. The second pressing member 321 has a second inclined surface 321S that is inclined with respect to the front-rear and left-right directions when viewed from the vertical direction. The first inclined surface 311S corresponds to the opposite right-angle side (hypotenuse) when viewed from the vertical direction of the first pressing member 311. The second inclined surface 321S corresponds to the opposite right-angle side (hypotenuse) when viewed from the vertical direction of the second pressing member 321. The first inclined surface 311S and the second inclined surface 321S are inclined in opposite directions when viewed from the vertical direction. 【0069】 The first inclined surface 311S and the second inclined surface 321S are each inclined linearly when viewed from the vertical direction. However, this is not limited to this. As a variation, although not shown in the figures, the first inclined surface 311S and the second inclined surface 321S may each be inclined curvilinearly (for example, in an arc) when viewed from the vertical direction. 【0070】 Here, as shown in Figure 13, the first frame 31 and the second frame 32 are inserted within the region between the first guide 110 and the second guide 120 in the left-right direction. When the base member 3 is positioned in a predetermined location, the front-rear direction of the base member 3 is parallel to the front-rear direction of the bathtub 1, and the left-right direction of the base member 3 is parallel to the left-right direction of the bathtub 1. Furthermore, when the base member 3 is positioned in a predetermined location, the left-right centers of the first frame 31 and the second frame 32 are aligned with the left-right centers of the first guide 110 and the second guide 120. In other words, if the base member 3 is positioned to the left or right of the left-right centers of the first guide 110 and the second guide 120, it is necessary to correct the deviation. 【0071】 Therefore, the base member 3 is provided with a first pressing member 311 and a second pressing member 321. The base member 3 is positioned in a predetermined location when the first pressing member 311 is pressed against the first centering portion 111 and the second pressing member 321 is pressed against the second centering portion 121. In other words, even if the first pressing member 311 is pressed against the first centering portion 111, the base member 3 will not be positioned in a predetermined location unless the second pressing member 321 is pressed against the second centering portion 121. Even if the second pressing member 321 is pressed against the second centering portion 121, the base member 3 will not be positioned in a predetermined location unless the first pressing member 311 is pressed against the first centering portion 111. 【0072】 To ensure that the first pressing member 311 is pressed against the first centering portion 111 and the second pressing member 321 is pressed against the second centering portion 121, the first pressing member 311 is provided with a first inclined surface 311S and the second pressing member 321 is provided with a second inclined surface 321S. When the first inclined surface 311S is pressed against the first centering portion 111 and the second inclined surface 321S is pressed against the second centering portion 121, the rear frame 30 becomes parallel to the left-right direction of the bathtub 1, the first frame 31 and the second frame 32 become parallel to the front-rear direction of the bathtub 1, and the left-right center of the base member 3 is positioned at the center between the left-right distance of the first guide 110 and the second guide 120. As a result, the base member 3 is positioned in a predetermined location (the transport device 2 is positioned at the bathing position). 【0073】 The first centering portion 111 has a first guide surface 1111 against which the first inclined surface 311S is pressed. The second centering portion 121 has a second guide surface 1211 against which the second inclined surface 321S is pressed. The first guide surface 1111 is inclined along the inclination direction of the first inclined surface 311S when the base member 3 is positioned in a predetermined location. In other words, the inclination direction of the first guide surface 1111 when viewed from above is the same as (i.e., parallel to) the inclination direction of the first inclined surface 311S when the base member 3 is positioned in a predetermined location. The second guide surface 1211 is inclined along the inclination direction of the second inclined surface 321S when the base member 3 is positioned in a predetermined location. In other words, the inclination direction of the second guide surface 1211 when viewed from above is the same as (i.e., parallel to) the inclination direction of the second inclined surface 321S when viewed from above, when the base member 3 is positioned in a predetermined location. 【0074】 Furthermore, the first centering section 111 has a first guide surface 1111 in addition to a first entry prevention surface 1112. The second centering section 121 has a second guide surface 1211 in addition to a second entry prevention surface 1212. Details will be described later. 【0075】 In this embodiment, when the base member 3 is inserted below the bathtub 1, even if the base member 3 is tilted relative to the front-to-back and left-to-right directions of the bathtub 1, the tilt of the base member 3 is eliminated, and the left-to-right center of the base member 3 is brought closer to the left-to-right center between the first guide 110 and the second guide 120. As a result, the transport device 2 is guided to the bathing position. In other words, a simple configuration can suppress misalignment of the transport device 2 connected to the bathtub 1. From the perspective of an assistant operating the transport device 2, it is convenient because the transport device 2 can be moved to the bathing position without having to intentionally perform any alignment work on the transport device 2. 【0076】 Furthermore, if the displacement of the transport device 2 connected to the bathtub 1 can be suppressed, problems such as the stretcher ST colliding with the upper edge 12E of the bathtub 1 can be suppressed when the support member 5 is lowered and the stretcher ST is placed into the bathing space BS. 【0077】 Furthermore, in this embodiment, the first inclined surface 311S of the first pressing member 311 is pressed against the first centering portion 111 of the first guide 110, and the second inclined surface 321S of the second pressing member 321 is pressed against the second centering portion 121 of the second guide 120, thereby enabling the base member 3 to move smoothly to a predetermined position. 【0078】 The above effects will be explained in detail below. Figures 13 to 15, which will be referenced in the following explanation, schematically show the position of the base member 3 when viewed from above. In the following explanation, when the base member 3 is inserted below the bathtub 1, it will be assumed that the base member 3 is tilted downwards to the right as a whole when viewed from above, as shown in Figure 14. 【0079】 In this case, first, the front end of the second frame 32 comes into contact with the second guide 120 (see upper diagram of Figure 14). Here, although omitted in Figures 13 to 15, the first frame 31 and the second frame 32 each have a rotating body RB at their front end that rotates around an axis extending in the vertical direction. Therefore, the rotating body RB of the second frame 32 comes into contact with the second guide 120. 【0080】 Suppose that the base member 3 is pushed further forward while it is tilted. In this case, the first inclined surface 311S of the first pressing member 311 is pressed against the first guide surface 1111 of the first centering portion 111. 【0081】 Then, the right portion of the base member 3 rotates counterclockwise around the point of contact between the first pressing member 311 and the first centering portion 111 (see Figure 14, lower diagram). At this time, the rotating body RB of the second frame 32 is in contact with the second guide 120, so the base member 3 rotates smoothly. 【0082】 Subsequently, the base member 3 rotates, eliminating its tilt, but it is positioned slightly to the left (see Figure 15, upper). Here, the part of the first pressing member 311 that presses against the first centering portion 111 is the first inclined surface 311S. Therefore, by pushing the base member 3 further, it can still move. At this time, the base member 3 moves forward while gradually shifting its position to the right in the left-right direction (see Figure 15, lower). 【0083】 As a result, the first inclined surface 311S of the first pressing member 311 is pressed against the first centering portion 111, and the second inclined surface 321S of the second pressing member 321 is pressed against the second centering portion 121. At this time, the tilt of the base member 3 is eliminated, and the left-right center of the base member 3 is moved towards the left-right center between the first guide 110 and the second guide 120, resulting in the state shown in Figure 13. In other words, by pushing the base member 3 in until it stops moving, the tilt of the base member 3 is eliminated, and the left-right center of the base member 3 is moved towards the left-right center between the first guide 110 and the second guide 120. This allows the transport device 2 to be guided to the bathing position and the bathtub 1 and the transport device 2 to be connected simply by inserting the base member 3 below the bathtub 1. 【0084】 Furthermore, in this embodiment, by making the first guide surface 1111 of the first centering portion 111 an inclined surface, the first inclined surface 311S that is pressed against the first guide surface 1111 can be smoothly slid, and by making the second guide surface 1211 of the second centering portion 121 an inclined surface, the second inclined surface 321S that is pressed against the second guide surface 1211 can be smoothly slid. As a result, the base member 3 inserted below the bathtub 1 can be smoothly pushed forward. 【0085】 Furthermore, in this embodiment, the first pressing member 311 and the second pressing member 321 are each formed in the shape of a right triangle when viewed from above. This makes it easier to fix the first pressing member 311 to the corner formed by the first frame 31 and the rear frame 30. It also makes it easier to fix the second pressing member 321 to the corner formed by the second frame 32 and the rear frame 30. 【0086】 In this embodiment, the first guide 110 has a first intrusion prevention surface 1112. The first intrusion prevention surface 1112 extends parallel to the left and right from the end of the first guide surface 1111 when viewed from the top and bottom, toward the area between the first guide 110 and the second guide 120 in the left and right direction. The second guide 120 has a second intrusion prevention surface 1212. The second intrusion prevention surface 1212 extends parallel to the left and right from the end of the second guide surface 1211 when viewed from the top and bottom, toward the area between the first guide 110 and the second guide 120 in the left and right direction. 【0087】 As a result, even if the base member 3 attempts to be inserted outside the area between the first guide 110 and the second guide 120 in the left-right direction, the front end of the base member 3 will abut against the first entry prevention surface 1112 or the second entry prevention surface 1212. Consequently, it is possible to prevent the base member 3 from being inserted in an unintended position. 【0088】 <3-2. Modified versions of the position adjustment mechanism> 1. First modified example of the position adjustment mechanism In the first modified example, as shown in Figure 16, the spacing G is larger than in the above embodiment (see Figure 13). Spacing G is the left-right spacing between the first guide 110 and the first frame 31 when the base member 3 is positioned in a predetermined location, and the left-right spacing between the second guide 120 and the second frame 32 when the base member 3 is positioned in a predetermined location. 【0089】 In the first modified example, the larger spacing G makes it easier to insert the base member 3 into the area between the first guide 110 and the second guide 120 in the left-right direction. As a result, the first frame 31 is less likely to collide with the first guide 110, and the second frame 32 is less likely to collide with the second guide 120. This reduces the impact on bathers riding on the transport device 2. Furthermore, even with a large spacing G, centering is performed by the first pressing member 311 and the second pressing member 321, thus preventing the transport device 2 from shifting position. 【0090】 2. Second modified example of the position adjustment mechanism In the second modified example, as shown in Figure 17, the length L is shorter than in the above embodiment (see Figure 13). The length L is the length of the first frame 31 and the second frame 32 in the front-to-back direction, respectively. 【0091】 In the second modified example, the shorter length L makes it easier to insert the base member 3 into the area between the first guide 110 and the second guide 120 in the left-right direction. This makes it less likely for the first frame 31 to collide with the first guide 110, and less likely for the second frame 32 to collide with the second guide 120. This reduces the impact on bathers riding on the transport device 2. Furthermore, even with a shorter length L, centering is performed by the first pressing member 311 and the second pressing member 321, thus preventing the transport device 2 from shifting position. 【0092】 3. Third modified example of the position adjustment mechanism In the third modified example, as shown in Figure 18, with the base member 3 positioned in a predetermined location, the first frame 31 and the second frame 32 are positioned outside the area between the first guide 110 and the second guide 120 in the left-right direction. In other words, with the base member 3 positioned in a predetermined location, the first guide 110 and the second guide 120 are positioned within the area between the first frame 31 and the second frame 32 in the left-right direction. 【0093】 In this case, unlike the above embodiment, the first pressing member 311 is positioned to the right of the first frame 31, and the second pressing member 321 is positioned to the left of the second frame 32. The first guide surface 1111 is inclined in the opposite direction to the first guide surface 1111 in the above embodiment. The second guide surface 1211 is inclined in the opposite direction to the second guide surface 1211 in the above embodiment. 【0094】 In a configuration where the first frame 31 and the second frame 32 are positioned outside the area between the first guide 110 and the second guide 120 in the left-right direction, the first guide 110 and the second guide 120 are connected to each other. However, the first guide 110 and the second guide 120 do not necessarily have to be connected to each other. 【0095】 In the third modified example, new members can be added to the left side of the first frame 31 and to the right side of the second frame 32. For example, although not shown, frames with wheels W attached may be added to the left side of the first frame 31 and to the right side of the second frame 32. This allows the transport equipment 2 to be moved more stably. 【0096】 <4. Auxiliary wheels> As shown in Figures 1, 2, 5, and 8, the conveying device 2 is equipped with an auxiliary wheel Wa. There is one auxiliary wheel Wa installed. 【0097】 The auxiliary wheel Wa is positioned further rear than the wheel W attached to the rear frame 30 of the base member 3. Specifically, the auxiliary wheel Wa is attached to the lower surface of a fixing member 40 that protrudes rearward from the rear frame 30. By being attached to the fixing member 40, the auxiliary wheel Wa is positioned in the center of the base member 3 in the left-right direction. 【0098】 Furthermore, the auxiliary wheel Wa is positioned so that its contact point with the floor surface FL is higher than that of all other wheels W. Specifically, when the transport device 2 is in a normal position (see Figures 2 and 8), all wheels W are in contact with the floor surface FL. At this time, the auxiliary wheel Wa is not in contact with the floor surface FL. In other words, the auxiliary wheel Wa is positioned higher than all other wheels W. 【0099】 The auxiliary wheel Wa has the function of assisting in the movement of the transport device 2. In particular, it can assist in the operation of pulling the transport device 2 backward. This will be explained in detail below. 【0100】 As shown in Figure 19, when the transport device 2 is moving backward, it may unintentionally tilt backward and nearly tip over backward. However, because the transport device 2 is equipped with auxiliary wheels Wa, even if the transport device 2 is about to tip over backward, the auxiliary wheels Wa will make contact with the floor surface FL (see the right diagram in Figure 19). This prevents the transport device 2 from tipping over. 【0101】 As a modified example, the auxiliary wheels Wa may be omitted from the conveying device 2, as shown in Figure 20. However, if the auxiliary wheels Wa are omitted from the conveying device 2, the conveying device 2 will tilt significantly backward when it is about to tip over backward (see the right diagram in Figure 20). 【0102】 Therefore, it is preferable to use a transport device 2 (see Figure 19) equipped with auxiliary wheels Wa. If the transport device 2 is equipped with auxiliary wheels Wa, even if the transport device 2 is about to tip over backward, it is possible to prevent the transport device 2 from tilting significantly backward. 【0103】 Furthermore, as shown in Figures 21 and 22, when the transport device 2 is moved backward, suppose there is an upward step SU in its path. In this case, if auxiliary wheels Wa are installed on the transport device 2, the transport device 2 can continue to move without tilting significantly. 【0104】 Specifically, when there is an upward step SU in the movement path of the transport device 2, the auxiliary wheel Wa first makes contact with the upward step SU (see the left diagram in Figure 21). Here, the contact point of the auxiliary wheel Wa with respect to the floor surface FL is higher than that of the other wheels W. Therefore, when the auxiliary wheel Wa overcomes the upward step SU, the transport device 2 does not tilt significantly (see the right diagram in Figure 21). Once the auxiliary wheel Wa overcomes the upward step SU, the auxiliary wheel Wa makes contact with the upper surface of the upward step SU. At this time, the front wheel W remains in contact with the floor surface FL, but the rear wheel W moves upward from the floor surface FL. 【0105】 In this state, if the transport device 2 continues to move, the rear wheels W will come into contact with the step SU (see the left diagram in Figure 22). At this time, the rear wheels W remain lifted off the floor FL. Therefore, even if the transport device 2 continues to move, the transport device 2 will not tilt significantly, and the rear wheels W will overcome the step SU (see the right diagram in Figure 22). 【0106】 Thus, when auxiliary wheels Wa are installed on the transport device 2, even if there is an upward step SU in the path of the transport device 2 moving backward, the transport device 2 can continue to move without tilting significantly. This reduces the burden on the operator of the transport device 2 (i.e., the caregiver). In addition, since the transport device 2 does not tilt suddenly and significantly, it can reduce the fear of the person bathing who is riding on the transport device 2. 【0107】 Although not shown in the diagram, a configuration to prevent the transport device 2 from tipping over could be considered in which a rod-shaped foot is installed in place of the auxiliary wheel Wa at the same position as the auxiliary wheel Wa. However, in this configuration, if there is an upward step SU, the foot may get caught on the upward step SU, causing the transport device 2 to tip over. For this reason, it is more preferable to install auxiliary wheel Wa on the transport device 2 to prevent it from tipping over. 【0108】 <5. Operating handle> As shown in Figures 1, 2, and 5, the transport device 2 is equipped with an operating handle 6. The operating handle 6 is fixed to the main body 51 of the support member 5. The operating handle 6 is grasped by the operator (i.e., assistant) of the transport device 2. The operator of the transport device 2 grasps the operating handle 6 and pushes or pulls the transport device 2. 【0109】 As shown in Figure 23, the operating handle 6 has a pair of gripping parts 60 that are grasped by the operator of the transport equipment 2. One gripping part 60 is located on the left side of the support member 5, and the other gripping part 60 is located on the right side of the support member 5. When the base member 3 is in a predetermined position, the operating handle 6, when viewed from above, is located outside the outer edge of the side part 12 and extends away from the side part 12. 【0110】 Specifically, each of the pair of gripping portions 60 extends rearward from the support member 5. When viewed from above, the pair of gripping portions 60 are inclined to spread apart from each other from front to rear. When the base member 3 is positioned in a predetermined location, when viewed from above, the left gripping portion 60 extends diagonally to the left and rearward from the support member 5, and the right gripping portion 60 extends diagonally to the right and rearward from the support member 5. 【0111】 In this configuration, when the base member 3 is positioned in a predetermined location, a space SP1 is created between the side 12 of the bathtub 1 and the operating handle 6. In Figure 23, the space SP1 is shown with a hatched pattern. This allows an assistant to stand between the side 12 of the bathtub 1 and the operating handle 6, thereby improving the assistant's work efficiency. 【0112】 However, the configuration of the operating handle 6 is not particularly limited. 【0113】 For example, as shown in Figure 24, the pair of gripping parts 60 may extend parallel to each other from the side of the support member 5 toward the rear when viewed from above. In other words, the pair of gripping parts 60 do not need to spread out to the left and right when viewed from above. In the configuration shown in Figure 24, the lateral protrusion of the operating handle 6 is smaller compared to the configuration shown in Figure 23, making it easier for the caregiver to work. 【0114】 Furthermore, as shown in Figure 25, the operating handle 6 may be rotatable relative to the support member 5. For example, the operating handle 6 is an annular shape that is elongated in one direction when viewed from the front-rear direction. The operating handle 6 is attached to the rear surface of the support member 5 and rotates around a pivot axis A1 that extends in the front-rear direction. Also, the width of the annular body constituting the operating handle 6 in the short-side direction is smaller than the width of the support member 5 in the left-right direction. 【0115】 When moving the transport device 2, the operating handle 6 is held so that its longitudinal direction is to the left and right (see upper diagram of Figure 25). This makes it easier to grip the operating handle 6. On the other hand, when assisting with bathing, the operating handle 6 is held so that its short direction is to the left and right (see lower diagram of Figure 25). This suppresses the protrusion of the operating handle 6 in the left and right directions, making it easier for the caregiver to work. 【0116】 Furthermore, as shown in Figure 26, the operating handle 6 may be retractable into the support member 5. For example, one gripping part 60 is attached to a rotating shaft A2 provided on the left side of the support member 5. The other gripping part 60 is attached to a rotating shaft A2 provided on the right side of the support member 5. Each of the pair of gripping parts 60 rotates with the rotating shaft A2 as a pivot point, swinging its free end up and down. 【0117】 When moving the conveying device 2, the pair of gripping portions 60 extend left and right respectively (see the upper figure in FIG. 26). This makes it easier to grip the operation handle 6. On the other hand, when performing bathing assistance, the pair of gripping portions 60 are respectively housed in the support member 5 (see the lower figure in FIG. 26). As a result, the protrusion of the operation handle 6 in the left-right direction is suppressed, making it easier for the assistant to work. 【0118】 Also, as shown in FIG. 27, the pair of gripping portions 60 of the operation handle 6 may each be of a belt type. In this configuration, the protrusion of the operation handle 6 in the left-right direction can be substantially eliminated. 【0119】 Although not shown, the operation handle 6 may be detachable from the support member 5. Also, the operation handle 6 may be omitted. 【0120】 The embodiments disclosed this time should be considered as illustrative in all respects and not restrictive. The scope of the present invention is shown not by the description of the above embodiments but by the claims, and further includes all modifications within the meaning and scope equivalent to the claims. 【Explanation of Signs】 【0121】 1 Bathtub 2 Conveying device 3 Base member 4 Support column 5 Support member 11 Bottom 12 Side 30 Rear frame 31 First frame 32 Second frame 52 Arm 100 Bathing device 110 First guide 111 First centering portion 120 Second guide <舍 121 Second centering portion 311 First pressing member 311S First inclined surface 321 Second pressing member 321S Second inclined surface 1111 First guide surface 1112 First entry prevention surface 1211 Second guide surface 1212 Second entry prevention surface BS Bathing space FL Floor surface W Wheel
