As described above, the second slide portion 4 is supported by the second guide portion 24 so as to be movable (rotatable) in a rotation direction (hereinafter referred to as “second slide direction”) around the central axis 240. Note that the (−Y) side surface of the second slide portion 4 supported by the second guide portion 24 is positioned on substantially the same plane as the region of the bottom surface 21 excluding the grooves 211 and 212 and the recess 213. .

  In the vicinity of the outer edge (near the tip of an arcuate part 412 described later) on the (+ Y) side surface of the main body 41 of the second slide part 4, a part slightly protruding in the (+ Y) side (narrow in FIG. 2) A portion shown by a broken line) is formed, and the slide engaging portion 44 is configured by the portion and the portion of the main body 41 that substantially overlaps the portion in the Y direction. That is, the vicinity of the tip of an arc-shaped portion 412 described later is the slide engagement portion 44. The second slide portion 4 has two slide engagement portions 44, and the two slide engagement portions 44 are arranged at positions that are point-symmetric with respect to the center (center hole 411) of the main body 41. Further, on the (−Y) side surface of the main body 241 of the second guide portion 24, the second slide portion 4 (in FIG. 2) in which the protrusion 43 and the cylindrical portion 42 are inserted into the second guide portion 24. The two grooves 261 in which the two slide engaging portions 44 of the second slide portion 4) indicated by a two-dot chain line are disposed are formed (in FIG. 2, only one groove is denoted by reference numeral 261). The same applies to the groove 262 described later). On the surface of the main body 241, a groove 263, a groove 262, and a groove 264 are sequentially formed adjacent to each groove 261 in the counterclockwise direction of FIG. 2 centering on the central axis 240. The groove 262 is shallower than the other grooves 261, 263, and 264.

  When the second slide part 4 is attached to the attachment main body 2, the protrusion 43 and the cylindrical part 42 of the second slide part 4 are inserted into the second guide part 24 as described above. At this time, each slide engagement portion 44 (more precisely, the (+ Y) side portion of the slide engagement portion 44) is disposed in the groove 261. Then, by rotating the second slide portion 4 about the central axis 240 by a slight angle counterclockwise in FIG. 2, the slide engagement portion 44 is disposed in the groove 263 and the both engage with each other. The movement of the two slide portions 4 is locked (that is, the position of the second slide portion 4 is locked). As a result, the second slide portion 4 is disposed at the position shown in FIG. 1 (hereinafter referred to as “retreat position”). In the retracted position, the entire second slide portion 4 overlaps the bottom surface 21 in the Y direction. In the following description, the groove 263 shown in FIG. 2 is referred to as a “retracted position locking portion 263”.

  In the main body 41 of the second slide portion 4, two arc-shaped parts 412 are formed along the circumferential direction with the center hole 411 as the center, and each part 412 is supported by the main body 41 in a cantilever state. The slide engagement portion 44 is formed at the tip (free end) of the plate spring-like portion 412, and when the slide engagement portion 44 moves from the groove 261 to the groove 263, the portion 412 bends. Thus, it is possible to move (turn) the second slide portion 4 with a relatively small force (the same applies to the movement from the groove 263 described later to the groove 264 via the groove 262).

  Further, when the second slide portion 4 is further rotated counterclockwise, each slide engagement portion 44 slides in the relatively shallow groove 262 and reaches the end of the groove 262. When the second slide portion 4 is further rotated counterclockwise by a slight angle, the slide engagement portion 44 is disposed in the groove 264 and engaged with each other, and the movement of the second slide portion 4 is locked. . As a result, the second slide portion 4 is disposed at the position shown in FIG. 3 (hereinafter referred to as “second protruding position”). In the following description, the groove 264 shown in FIG. 2 is referred to as a “projection position locking portion 264”. In the second projecting position, a through hole 49 (hereinafter referred to as “second through hole 49”) formed in the main body projecting portion 45 of the second slide portion 4 is outside the side surface on the (+ Z) side of the mounting main body 2. Located in. The 2nd through-hole 49 is a hole for the below-mentioned attachment screw insertion.

  FIG. 4 is a bottom view of the mounting structure 1 and shows a state in which the first slide portion 3 and the second slide portion 4 are arranged at the rail engagement position and the retracted position, respectively. FIG. 5 is a cross-sectional view at the position of the arrow AA in FIG. 4 and shows only the vicinity of the first slide portion 3 and the bottom surface 21 of the mounting body 2. In FIG. 5, each member is shown with the thickness in the Y direction larger than the actual thickness (the same applies to FIG. 7 described later).

  When the attachment body 2 is attached to the support rail 81, the first slide portion 3 is disposed at the rail engagement position. And while the other edge 812 of the support rail 81 is sandwiched between the rail engaging portion 22 and the bottom surface of the rail groove 211 (surface perpendicular to the Y direction), the other edge 812 of the support rail 81 is The first slide portion 3 is pressed against the end portion 35 on the (+ Z) side. As shown in FIG. 5, an inclined surface 351 in which the thickness of the main body 31 in the Y direction gradually decreases toward the (+ Z) direction on the (−Y) side surface of the end portion 35 of the first slide portion 3. Is formed. Further, as described above, the slide engaging portion 34 locked in the engaging position locking portion 253 shown in FIG. 4 is provided in the vicinity of the free end of the long member 33 that is long in the X direction. Therefore, as the edge 812 of the support rail 81 is applied to the inclined surface 351 and pushed in the (+ Y) direction, the long member 33 is elastically deformed, and the main body 31 of the first slide portion 3 is perpendicular to the longitudinal direction of the support rail 81. Move in the first sliding direction (more precisely, the (−Z) direction).

  When the edge 812 of the support rail 81 passes through the (+ Z) side of the end portion 35 of the first slide portion 3 and reaches the bottom surface of the rail groove 211, the first slide portion 3 is returned to the original position (the long member). 33 is a position that is not deformed and returns to the position shown in FIG. 4, and the edge 812 of the support rail 81 is sandwiched between the end portion 35 of the first slide portion 3 and the bottom surface of the rail groove 211. The That is, the first slide portion 3 engages with the edge 812 of the support rail 81 at the rail engagement position. In addition, since the 2nd slide part 4 is not utilized by the attachment to the support rail 81 of the attachment main body 2, the 2nd slide part 4 is arrange | positioned in the retreat position where the 2nd through-hole 49 is located on the bottom face 21, and 2nd The entire slide portion 4 overlaps the bottom surface 21. Therefore, when the mounting body 2 is mounted on the support rail 81, the second slide portion 4 does not interfere with the mounting operation or the arrangement of other members.

  FIG. 6 is a bottom view of the mounting structure 1 and shows a state in which the first slide portion 3 and the second slide portion 4 are arranged at the first protruding position and the second protruding position, respectively. FIG. 7 is a cross-sectional view at the position of the arrow BB in FIG. 6 and shows only the vicinity of the first slide portion 3 and the bottom surface 21 of the mounting body 2.

  When the attachment body 2 is directly attached to the attachment surface, the first slide portion 3 is pulled out to the first protruding position, and the second slide portion 4 is pulled out to the second protruding position. As a result, the first through hole 39 of the first slide part 3 and the second through hole 49 of the second slide part 4 are positioned outside the side surface of the mounting body 2. And the attachment main body 2 is directly attached to an attachment surface by inserting an attachment screw in each through-hole 39, 49 and fastening the said screw to an attachment surface. At this time, as shown in FIG. 7, both sides of each slide engagement portion 34 in the Y direction perpendicular to the bottom surface 21 abut against the protruding position locking portion 254 and the mounting surface 80, that is, the slide engagement portion 34 is It is sandwiched between the protruding position locking portion 254 and the mounting surface 80. Thereby, the 1st slide part 3 is firmly fixed with respect to the attachment main body 2. FIG. Similarly, in the second slide portion 4 of FIG. 6, both sides of the slide engagement portion 44 in the Y direction come into contact with the protruding position locking portion 264 and the attachment surface 80, so that the second slide portion 4 is attached to the attachment body 2. It is firmly fixed against.

  As shown in FIGS. 1 and 2, a plate-like auxiliary protrusion 243 is formed on the (+ Z) side portion of the main body 241 of the second guide portion 24, and the main body protrusion 45 of the second slide portion 4. Has an engaging groove 451 formed so that the auxiliary protrusion 243 is inserted when it is arranged at the second protruding position. Therefore, in the state where the second slide portion 4 is disposed at the second protruding position (position shown in FIG. 3), a force in a direction perpendicular to the bottom surface 21 of the mounting body 2 acts on the main body protruding portion 45. Even in this case, when the inner surface of the engagement groove 451 and the auxiliary projection 243 (see FIG. 1) of the second guide 24 abut, the projection 43 and the second guide that support the movement of the second slide portion 4. The 24 protrusions 242 (see FIG. 2) are prevented from being damaged.

  FIG. 8 is a bottom view showing a mounting structure 90 of a comparative example, and FIG. 9 is a cross-sectional view at the position of arrow CC in FIG. In the attachment structure 90 of the comparative example, both the first slide portion 91 and the second slide portion 92 are movable in the same slide direction (Z direction in FIG. 8). When the attachment main body 93 is attached to the support rail 81, the first slide portion 91 and the second slide portion 92 are disposed at the positions indicated by the two-dot chain line in FIG. 811 respectively. Further, when the attachment main body 93 is directly attached to the attachment surface, the first slide portion 91 and the second slide portion 92 are arranged at the positions indicated by solid lines in FIG. 8, and the through holes 911 and 921 are used. The attachment main body 93 is attached to the attachment surface 80. In this case, in the first slide portion 91, as shown in FIG. 9, an engagement portion 912 provided at the tip of a member supported in a cantilever state has an engagement hole formed in the bottom surface of the mounting body 93. The first slide portion 91 is fixed (locked) to the mounting body 93 by engaging with 932. The second slide portion 92 is also fixed to the mounting body 93 by the same mechanism.

  However, in the lock mechanism of FIG. 9, since there is a relatively large gap between the mounting surface 80 and the engaging portion 912, when a large external force is applied to the mounting body 93, a two-dot chain line in FIG. 9. As shown in FIG. 8, there is a possibility that the engaging portion 912 is detached from the locking hole 932 and the lock of the first slide portion 91 is released (the same applies to the second slide portion 92). When the lock is released in both the first slide portion 91 and the second slide portion 92, the attachment main body 93 moves greatly in the slide direction (Z direction).

  On the other hand, in the mounting structure 1, the slide in the direction perpendicular to the bottom surface 21 of the mounting body 2 in the state where the first slide portion 3 is disposed at the first protruding position and the mounting body 2 is directly mounted on the mounting surface 80. Both sides of the engaging portion 34 abut against the protruding position locking portion 254 and the mounting surface 80, respectively. Thereby, in the case of direct attachment to the attachment surface 80, the slide engagement portion 34 is prevented from being detached from the protruding position locking portion 254, and the first slide portion 3 is firmly fixed to the attachment body 2. be able to. Further, in a state where the second slide portion 4 is disposed at the second protruding position and the mounting body 2 is directly mounted on the mounting surface 80, both sides of the slide engaging portion 44 in the direction perpendicular to the bottom surface 21 of the mounting body 2 are The second slide portion 4 can be firmly fixed to the mounting body 2 by coming into contact with the protruding position locking portion 264 and the mounting surface 80, respectively.

  In the case of direct attachment to the attachment surface 80, the first slide portion 3 has a plurality of slide engagement portions 34 that abut against the protruding position locking portion 254 and the attachment surface 80, respectively. Can be more firmly fixed to the mounting body 2. Further, since the second slide portion 4 has a plurality of slide engagement portions 44 that respectively contact the protruding position locking portion 264 and the attachment surface 80, the second slide portion 4 is stronger than the attachment main body 2. Can be fixed to.

  In the mounting structure 1, the first slide direction in the first slide portion 3 is different from the second slide direction in the second slide portion 4. Thus, in the mounting structure 1 that can be selected to be directly mounted on the mounting surface 80 and mounted on the support rail 81 by the movement of the two slide portions 3 and 4, the first slide is temporarily assumed during the direct mounting. Even when the lock is released in both the part 3 and the second slide part 4, it is possible to prevent the mounting body 2 from moving greatly in either direction. In other words, in the attachment structure 1, the first guide portion 23 and the second guide portion 24 prevent the attachment main body 2 directly attached to the attachment surface 80 from moving greatly in either direction, so that sliding engagement is possible. It is possible to more reliably prevent the engagement between the portions 34 and 44 and the protruding position locking portions 254 and 264 from being released.

  Further, since the second slide direction in the second slide portion 4 is a rotation direction around the central axis 240 perpendicular to the bottom surface 21 of the mounting body 2, the second slide portion 4 is disposed at the second protruding position. In the state where the second slide part 4 protrudes from the side surface of the mounting body 2, a member that resists the force in the Y direction to the part (in the above example, the engagement groove 451 of the second slide part 4 is provided). In addition, the auxiliary protrusion 243) of the second guide portion 24 can be easily provided.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.

  The first slide direction and the second slide direction may be various directions along the bottom surface 21 of the mounting body 2 as long as they are different from each other. For example, the first slide direction in the first slide portion 3 is perpendicular to the bottom surface 21. The rotation direction may be about an axis. In this case, the first slide portion 3 is provided with a portion that protrudes toward the rail groove 211 in a state of being arranged at the rail engagement position, and the support rail 81 is attached when the attachment body 2 is attached to the support rail 81. The portion engages with the edge 812 of the. Further, the first guide portion 23 and the second guide portion 24 provided on the bottom surface 21 of the mounting body 2 can employ various structures other than those described above.

  In the above-described embodiment, the concave engagement position locking portion 253, the protruding position locking portions 254 and 264, and the retreat position locking portion 263 are formed on the bottom surface 21 of the mounting body 2, and the slide engagement having a convex portion. The joint portions 34 and 44 engage with these locking portions, but the engagement position locking portion 253, the protruding position locking portions 254 and 264, and the retracted position locking portion 263 are convex on the bottom surface 21 of the mounting body 2. The slide engaging portions 34 and 44 having concave portions may be engaged with these locking portions. Further, a portion protruding to the (−Y) side is added in the engaging portion 912 of FIG. 9, and when the engaging portion 912 is in contact with the locking hole 932, the portion is in contact with the mounting surface 80. The slide part may be firmly fixed to the mounting body.

  For example, the (−X) side engaging position locking portion 253 and the (+ X) side protruding position locking portion 254 of FIG. 2 are omitted, and the first slide portion 3 is disposed at the rail engaging position. Only one slide engagement portion 34 is engaged with the engagement position locking portion 253, and when the first slide portion 3 is disposed at the first protruding position, only the other slide engagement portion 34 is locked at the protruding position locking. The portion 254 may be engaged. That is, the slide engaging portion 34 that locks the first slide portion 3 at the rail engaging position and the first protruding position may be different members.

  In the mounting structure 1 of FIG. 1, when the mounting body 2 is directly mounted on the mounting surface 80, the first slide portion 3 and the second slide portion 4 are locked at the first protruding position and the second protruding position. In the mounting structure 1 in which the first slide direction and the second slide direction are different, even when the first slide portion 3 and the second slide portion 4 are not locked in direct mounting, the mounting body 2 moves greatly in either direction. It is possible to fix the mounting body 2 against external forces in all directions.

  In the mounting structure 1 of FIG. 1, the second slide portion 4 does not contribute to the mounting of the mounting body 2 to the support rail 81, and therefore the position of the second sliding portion 4 when mounting the mounting body 2 to the support rail 81 is It may be arbitrarily determined. Further, the second slide portion 4 is provided with a portion that protrudes toward the rail groove 211 in a state of being disposed at the retracted position, and one edge of the support rail 81 is attached when the attachment body 2 is attached to the support rail 81. The part may engage with 811. In this case, the rail engaging portion 22 of FIG. 1 provided on the bottom surface 21 of the mounting body 2 can be omitted. In other words, the rail engaging portion that engages with one edge 811 of the support rail 81 when the attachment main body 2 is attached to the support rail 81 may be realized by the second slide portion 4 disposed at the retracted position. .

  The mounting body 2 in the mounting structure 1 may be, for example, a member that supports the electric device 9 by fixing one surface of the electric device 9 in addition to the one that houses the electric device 9 therein.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
