Abstract

PROBLEM TO BE SOLVED: To prevent a main body and a cover from being easily unlocked, while suppressing the size of a structure protruding from an outer peripheral surface of a protector.SOLUTION: A protector comprises a main body, a cover and a lock member. The main body includes a first member on one sidewall and a through hole at a lower side of the first member. The cover includes a second member which opposes the first member with a plane including a mating surface interposed therebetween in the state where the main body and the cover are overlapped. One lock piece is inserted from a front face into the through hole in the state where the main body and the cover are overlapped and the lock member opposes the first member and the second member, thereby disposing the one lock piece at such a position that the one lock piece can be abutted to the first member from the lower side of the first member, and another lock piece is disposed at such a position that the other lock piece can be abutted to the second member from the upper side of the second member. Vertical movement of the first member and the second member is regulated, a catch of the one lock piece is locked to the first member and a catch of the other lock piece is locked to the second member.

Description

  The present invention relates to a protector that houses a wire harness.

  Conventionally, in order to protect the wire harness that is routed to the automobile and to regulate the route, the protector that allows the wire harness to be inserted inside, passes the wire harness through the saddle-shaped protector body, and then closes the top opening of the protector body with a lid. The protector body and the lid are locked.

  For example, in the protector of Patent Document 1, a lock arm (male lock portion) having a locking projection at the tip is formed on the lid, and a hole for engaging the locking projection of the lock arm is formed on the side wall of the main body. A formed frame portion (female lock portion) is formed. Then, when the lid is put on the main body, the locking projection of the lock arm is inserted and guided in the hole by the side wall of the main body, and the locking projection is engaged with the wall surface end of the frame portion to fix the main body and the lid. To do. In this protector, the closing direction of the lid and the direction of insertion into the hole of the lock arm are the same, so when an external force is applied and the protector is twisted, or when another object hooks the lock part, etc. There is a problem that the locking projection is released from the hole and the lock is easily released. Also, in order to suppress the occurrence of such unintentional unlocking, the locking protrusion is usually enlarged to increase the hole width, and the lock arm and hole wall are formed thick, There is also a problem that the size is increased and the wiring space outside the protector is insufficient.

  Therefore, the protector of Patent Document 2 includes flange portions extending along the extending direction of the end surface over the entire end surface at the end of the side wall of the main body and the end of the lid. These flange portions form one rail portion when the main body and the lid are overlapped, and an engagement hole extending between the main body and the lid is formed in a part of the rail portion. The lock member that fixes the main body and the lid forms a groove portion that can be fitted to the rail portion so as not to come out in a direction facing the rail surface, and has an engagement portion that engages with the engagement hole. . The groove of the lock member is slid from the side of the rail end in the rail extending direction to be fitted to the rail portion, and the fitted lock member is slid to the position of the engagement hole and pushed toward the engagement hole. As a result, the engaging portion of the lock member engages with the engaging hole, and the main body and the lid are fixed. According to this protector, the closing direction of the main body and the lid is different from the pushing direction of the lock member into the engagement hole. For this reason, even when the protector is twisted due to an external force or when another object hooks the lock member, the engagement state between the lock member and the engagement hole cannot be easily released. The main body and the lid can be more reliably fixed while reducing the size of the lock member itself as compared to the lock portion.

  However, in the technique of Patent Document 2, it is necessary to slide the lock member from the end of the rail in the rail extending direction to be fitted to the rail and then to the position of the engagement hole. For this reason, the rail portion extends outward from the outer peripheral surfaces of the main body and the lid, and extends so as to be longer than the engagement hole, that is, longer than the lock member. Therefore, the technique of Patent Document 2 has a problem that the lock structure (lock portion) including the rail portion and the lock member is enlarged as a whole.

  The present invention has been made to solve these problems, and a protector having a lock structure in which the lock state between the main body and the lid is not easily released while suppressing the size of the structure protruding from the outer peripheral surface of the protector. The purpose is to provide.

  In order to solve the above-described problem, a protector according to a first aspect includes a bowl-shaped main body, a lid that covers the upper surface opening of the main body by overlapping both ends on the upper ends of a pair of side walls of the main body, A pair of opposing locking pieces are erected on the bottom wall, and each of the pair of locking pieces has a locking claw at a tip portion thereof to fix the main body and the lid; And the main body is formed below the first member on one side wall of the pair of side walls, and is formed below the first member on the one side wall. A through-hole through which one of the locking pieces can be inserted, and the lid has the first surface across a plane including a mating surface of the main body and the lid in a state where the main body and the lid are overlapped. A second member facing the member; the main body and the lid; When the one locking piece of the locking member is inserted into the through-hole from the front in a state where the locking member is overlapped and the locking member faces the first member and the second member, The piece is disposed at a position where it can abut against the first member from the lower side of the first member, and the other locking piece is disposed at a position where it can abut against the second member from above the second member. The locking claw of the one locking piece is configured to restrict the movement of the first member and the second member in the separation direction and to prevent the locking member from coming off. The locking claw of the other locking piece is locked to the second member.

  The protector which concerns on a 2nd aspect is a protector which concerns on a 1st aspect, Comprising: The said 1st member and the said 2nd member are the said main body and the said lid | cover in the state with which the said main body and the said lid | cover were overlaid. It is provided inside the outer peripheral surface.

  The protector which concerns on a 3rd aspect is a protector which concerns on a 2nd aspect, Comprising: With the said main body and the said lid | cover being overlapped, each of the outer peripheral surface of the said locking member, the said main body, and the said lid | cover The outer peripheral surface is flush.

  A protector according to a fourth aspect is the protector according to any one of the first to third aspects, and is formed above the second member in the lid, and the other locking piece of the lock member A recess capable of accommodating at least a part of the second member, and in a state where the main body and the lid are overlapped, at least a part of the other locking piece is accommodated in the recess and is located above the second member. To the second member.

  In the invention according to any one of the first to fourth aspects, one locking piece of the lock member is seen from the front in a state where the main body and the lid are overlapped and the lock member faces the first member and the second member. Since it is inserted into the through hole, the first member and the second member can be downsized to the same length as the lock member. In addition, one locking piece is disposed at a position where it can come into contact with the first member from below the first member, and the other locking piece can come into contact with the second member from above the second member. The locking claw of one locking piece is attached to the first member so that the movement of the first member and the second member in the separating direction is restricted and the locking member can be prevented from coming off. Since the locking claw of the other locking piece is locked to the second member, the main body and the lid can be more reliably fixed while reducing the size of the locking member. Therefore, it is possible to prevent the lock state between the main body and the lid from being easily released while reducing the size of the structure protruding from the outer peripheral surface of the protector.

  According to the second aspect of the invention, since the first member and the second member are provided on the inner side of the outer peripheral surface of the main body and the lid in a state where the main body and the lid are overlapped, It can suppress that a lock member protrudes from an outer peripheral surface. Therefore, the size of the structure protruding from the outer peripheral surface of the protector can be further reduced.

  According to the third aspect of the invention, the outer peripheral surface of the lock member and the outer peripheral surfaces of the main body and the lid are flush with each other in a state where the main body and the lid are overlapped with each other. Thus, the lock member can be prevented from protruding. Therefore, the size of the structure protruding from the outer peripheral surface of the protector can be further reduced.

  According to the fourth aspect of the invention, a state in which the concave portion capable of accommodating at least a part of the other locking piece of the lock member is further provided above the second member of the lid, and the main body and the lid are overlapped with each other. Thus, at least a part of the other locking piece is accommodated in the recess and disposed at a position where it can come into contact with the second member from above the second member. Therefore, the size of the structure protruding from the outer peripheral surface of the protector can be reduced.

After the wire harness is inserted through the main body 20, the upper surface opening of the main body 20 is closed by covering the lid 30.

  The lid 30 includes an upper wall 31 and side walls 32 and 33 projecting from both ends of the upper wall 31 in the width direction. The side wall 32 is connected to the side wall 22 of the main body 20 via a thin hinge portion 49. The lid 30 rotates around the thin hinge portion 49, and the end of the side wall 33 of the lid 30 abuts on the upper end of the other side wall 23 of the main body 20, so that the lid 30 covers the upper opening of the main body 20. It is done.

  The lock member 50 is formed in a bowl shape in which a pair of locking pieces 52 and 53 facing each other are erected on the bottom wall 51. A groove portion 56 that fits with the members 24 and 34 is formed by the base portion of the pair of locking pieces 52 and 53 and the bottom wall 51. Locking claws 54 and 55 that face each other are provided at the tip portions of the pair of locking pieces 52 and 53, respectively. The lock member 50 fixes the main body 20 and the lid 30 in a state where the main body 20 is covered with the lid 30.

  A columnar member (“first member”) 24 extending in the longitudinal direction of the end surface of the side wall 23 is formed on one side wall 23 of the pair of side walls 22 and 23 of the main body 20. A columnar member (“second member”) 34 extending in the longitudinal direction of the end surface of the side wall 33 is formed on the side wall 33 of the lid 30. More specifically, the members 24 and 34 are respectively provided in a part of the longitudinal direction (longitudinal direction of the mating surface 41) of the side wall 23 and the lid 30 of the pair of side walls 22 and 23 of the main body 20. ing. The shapes of the members 24 and 34 are not limited to columnar shapes. The members 24 and 34 face each other across a plane including the mating surface 41 of the main body 20 and the lid 30 in a state where the main body 20 and the lid 30 are overlapped. The main body 20 and the lid 30 are overlapped so that the lock member 50 faces the members 24, 34, that is, the bottom surface of the groove portion 56 of the lock member 50 faces the members 24, 34. The lock member 50 is pushed into the members 24 and 34 along the insertion direction (direction indicated by the arrow Y1) toward the head. One locking piece 52 of the lock member 50 is inserted into the through hole 25 from the front of the through hole 25 described later, and the other locking piece 53 is inserted into the concave 35 from the front of the concave 35 described later. Be contained. As a result, the groove portion 56 of the lock member 50 and the members 24 and 34 are fitted, the locking claws 54 and 55 are locked to the members 24 and 34, and the main body 20 and the lid 30 are fixed.

  A member 24 is provided at the upper end portion of the side wall 23 of the main body 20. The member 24 is located on the inner side (the inner space 61 side of the protector 1) than the outer peripheral surface 29 of the main body 20, and the surface 72 on the outer side (the outer peripheral surface 29 side of the main body 20) of the member 24 is inward from the outer peripheral surface 29. The bottom surface of the recessed portion 42 is recessed. The member 24 is formed integrally with the side wall 23 so that the surface 72 and the inner peripheral surface 44 of the side wall 23 are included in the same plane. Note that the member 24 may be formed such that the surface 72 is positioned on the inner side or the outer side with respect to the inner peripheral surface 44.

  A member 34 is provided at the lower end portion of the side wall 33 of the lid 30. The member 34 is located on the inner side (on the inner space 61 side of the protector 1) than the outer peripheral surface 39 of the lid 30, and the surface 82 on the outer side (the outer peripheral surface 39 side of the lid 30) is inward from the outer peripheral surface 39. The bottom surface of the recessed portion 43 is recessed. The member 34 is formed integrally with the lid 30 so that the surface 82 and the inner peripheral surface 45 of the lid 30 are included in the same plane. The member 34 may be formed so that the surface 82 is located on the inner side or the outer side with respect to the inner peripheral surface 45. In the state where the main body 20 is covered with the lid 30, the outer peripheral surface 29 of the side wall 23 of the main body 20 and the outer peripheral surface 39 of the side wall 33 of the lid 30 are flush with each other, and the inner peripheral surface of the side wall 23 of the main body 20. 44 and the outer peripheral surface 39 of the side wall 33 of the lid 30 are also flush with each other.

  In a state where the main body 20 and the lid 30 are overlapped, the member 24 and the member 34 are provided on the inner side of the outer peripheral surfaces 29 and 39 of the main body 20 and the lid 30, so that the outer periphery of the protector 1 is The protrusion of the lock member 50 from the surface can be suppressed, and the size of the structure protruding from the outer peripheral surface can be made smaller. Even if the members 24 and 34 are not provided on the inner side of the outer peripheral surface of the protector 1, the member 24 is pushed by being pushed toward the members 24 and 34 with the lock member 50 facing the members 24 and 34. 34, the side walls 23 and 33 can be made smaller. Therefore, even if the members 24 and 34 are not provided inside the outer peripheral surface of the protector 1, the usefulness of the present invention is not impaired.

  Further, a through hole 25 penetrating the side wall 23 is formed in the side wall 23 of the main body 20 below the member 24. The through hole 25 is formed with an opening 26 on the inner peripheral surface 44 of the side wall 23, and the internal space of the through hole 25 communicates with the inner space of the recess 42. The through hole 25 is formed so that one of the pair of locking pieces 52 and 53 of the lock member 50 can be inserted.

  On the upper wall 31 of the lid 30, a recess 35 having a bottom surface 47 is formed above the member 34. The recess 35 is formed with an opening 36 on the inner peripheral surface 45 of the upper wall 31. The internal space of the recess 35 communicates with the internal space of the recess 43. The recess 35 is formed in a shape and size that can accommodate the locking piece. Then, in a state where the main body 20 and the lid 30 are overlapped, the locking piece 53 is inserted into the recess 35 along the upper surface 81 of the member 34 and accommodated, whereby the locking piece 53 is It arrange | positions in the position which can contact | abut to the member 34 from the upper side. The opening 36 is formed in a shape and size into which a locking claw 55 provided at the tip of the other locking piece 53 of the lock member 50 can be inserted. Accordingly, when the locking piece 53 is accommodated in the recess 35, the locking claw 55 protrudes from the opening 36 toward the inner space 61 and is locked to the upper end portion of the inner surface 84 of the member 34. The members 24 and 34 may be formed such that a gap is formed between the upper surface 73 of the member 24 and the lower surface 83 of the member 34 in a state where the lid 30 is covered with the main body 20.

  The vertical width of the through hole 25 is longer (slightly longer) than the thickness of the locking piece 52 of the lock member 50. The length of the through hole 25 in the longitudinal direction of the mating surface 41 of the main body 20 and the lid 30 is longer (slightly longer) than the length of the locking piece 52. The distance from the lower surface of the locking piece 52 of the locking member 50 to the tip of the locking claw 54 is wider than the vertical width of the through hole 25. In order to make it easier for the locking piece 52 to be inserted into the through hole 25, the upper surface of the locking claw 54 is closer to the lower surface of the locking piece 52 as the distal end side of the locking claw 54 (part side to be locked to the member 24). It is formed obliquely with respect to the lower surface of the locking piece 52 so as to increase the distance. Accordingly, the locking claw 54 of the locking piece 52 is inserted into the through hole 25 from the front along the lower surface 46 of the through hole 25 and the lower surface 71 of the member 24 by elastically deforming the locking piece 52. To a part of the inner surface 74.

  Further, the distance from the upper surface of the locking piece 53 of the locking member 50 to the tip of the locking claw 55 is wider than the vertical width of the recess 35. And in order to make the latching piece 53 easy to be accommodated in the recessed part 35, the lower surface of the latching claw 55 formed in the latching piece 53 is the tip side of the latching claw 55 (part side which latches to the member 34). It is formed obliquely with respect to the upper surface of the locking piece 53 so that the distance from the upper surface of the locking piece 53 increases. By inserting the locking piece 53 into the concave portion 35 along the upper surface 81 of the member 34 from the front surface, that is, from the front surface of the bottom surface 47 of the concave portion 35, the locking claw 55 of the locking piece 53 becomes a member. 34 is locked to the inner surface 84 of the ring.

  The lengths of the recessed portions 42 and 43 in the longitudinal direction of the mating surface 41 are longer (slightly longer) than the length along the extending direction of the groove portion 56 of the lock member 50 (the length of the bottom wall 51). Further, the recess width of the recess portions 42 and 43 is the same (substantially the same) as the thickness of the portion of the bottom wall 51 of the lock member 50 that fits into the recess portions 42 and 43.

  The length of the recess 35 in the longitudinal direction of the mating surface 41 is longer (slightly longer) than the length along the longitudinal direction of the bottom wall 51 and the locking piece 53 of the lock member 50. The depth of the recess 35, that is, the distance from the outer surfaces 72, 82 of the members 24, 34 to the bottom surface 47 of the recess 35 (the surface extending in the longitudinal direction of the mating surface 41) is the bottom surface of the groove 56 of the lock member 50. And the same length (substantially the same) as the distance from the tip of the locking piece 53. The width of the recess 35, that is, the width between the outer peripheral surface and the inner peripheral surface of the upper wall 31 is the same (substantially the same) as the thickness of the locking piece 53. The width of the opening 36 of the recess 35 along the insertion direction indicated by the arrow Y1 of the lock member 50 is longer (slightly longer) than the length along the insertion direction of the locking claw 55 of the locking piece 53.

  The distance between the upper surface and the lower surface of the groove portion 56 of the lock member 50 is longer (slightly longer) than the distance between the upper surface 81 of the member 34 and the lower surface 71 of the member 24. Further, the distance between the upper surface of the groove portion 56 and the lower surface of the locking piece 52 is such that the upper surface 81 of the member 34 of the lid 30 and the lower surface 46 of the through hole 25 of the main body 20 (surface extending in the longitudinal direction of the mating surface 41). Are formed at the same (substantially the same) interval.

  As described above, the length of each part of the lock member 50 in the longitudinal direction of the mating surface 41 and the lengths of the through hole 25, the recessed parts 42 and 43, and the concave part 35 in the corresponding direction are set, and thus the lock member 50 is set. , The movement of the lock member 50 along the longitudinal direction of the mating surface 41 is restricted.

  Then, in a state where the main body 20 and the lid 30 are overlapped and the lock member 50 fixes the main body 20 and the lid 30, the outer peripheral surface 59 of the lock member 50 and the outer peripheral surfaces 29 of the main body 20 and the lid 30, The thickness of the lock member 50 is set along the outer peripheral surface 59 so as to be flush with 39 (see FIGS. 4 and 5). Thereby, the lock member 50 can be prevented from protruding from the outer peripheral surface of the protector 1, and the size of the structure protruding from the outer peripheral surface of the protector 1 can be further reduced. In addition, even if the outer peripheral surface 59 of the lock member 50 is formed outside the outer peripheral surface of the protector 1, the protector according to the comparative technique includes a male lock portion on one of the main body and the lid and a female lock portion on the other. Compared to 200, the lock member 50 itself can be made smaller. Therefore, even if the outer peripheral surface 59 of the lock member 50 is formed outside the outer peripheral surface of the protector 1, the usefulness of the present invention is not impaired.

  In the protector 1 configured as described above, the wire harness is inserted into the main body 20 with the lid 30 opened, and after insertion, the lid 30 is rotated in the closing direction with the thin hinge 49 as a fulcrum. By the rotation operation, both ends of the lid 30, that is, the lower ends of the side walls 32 and 33 are overlapped with the upper ends of the pair of side walls 22 and 23 of the main body 20, respectively. Thereby, the lid 30 covers and closes the upper surface opening of the main body 20.

  The main body 20 and the lid 30 are overlapped, and the lock member 50 faces the members 24 and 34, that is, the bottom surface of the groove portion 56 of the lock member 50 faces the members 24 and 34. The lock member 50 is pushed into the members 24 and 34 along the insertion direction (direction indicated by the arrow Y1) toward the member 34. One locking piece 52 of the locking member 50 is inserted into the through hole 25 while being elastically deformed from the front of the through hole 25 and inserted through the through hole 25, and the other locking piece 53 is inserted into the concave 35 from the front of the recess 35. It is inserted into the recess 35 while being elastically deformed. Then, the groove portion 56 of the lock member 50 and the members 24 and 34 are fitted, and one locking piece 52 is disposed at a position where it can contact the member 24 from below the member 24. Further, the other locking piece 53 of the lock member 50 is disposed at a position where it can contact the member 34 from above the member 34. Thereby, the locking pieces 52 and 53 restrict the movement of the members 24 and 34 in the separating direction (vertical direction). In the regulated state, the locking claw 54 provided on the locking piece 52 locks the member 24 and the locking claw 55 provided on the locking piece 53 so that the locking member 50 can be prevented from coming off. The member 34 is locked.

  The outer peripheral surface 59 of the lock member 50 is preferably flush with the outer peripheral surface of the protector 1, but as described above, the outer peripheral surface 59 of the lock member 50 is formed outside the outer peripheral surface of the protector 1. Even if it is done, it does not impair the usefulness of the present invention. Further, even if a part of the locking piece 53 accommodated in the recess 35 protrudes inward from the inner peripheral surface of the protector 1, the usefulness of the present invention is not impaired. Accordingly, the recess 35 is formed in a shape and size that can accommodate at least a part of the locking piece 53, and in a state where the main body 20 and the lid 30 are overlapped, at least a part of the locking piece 53 is The locking piece 53 may be disposed at a position where it can come into contact with the member 34 from the upper side of the member 34 by being inserted and accommodated in the recess 35 along the upper surface 81 of the member 34.

  Specifically, in such a configuration, for example, the lock member 50 is formed such that the thickness of the portion along the outer peripheral surface 59 of the lock member 50 is larger than the vertical width of the recess, and the lock member 50 The outer peripheral surface 59 is located outside the outer peripheral surface of the protector 1. Such a configuration is also realized when the recess 35 does not include the opening 36 and the locking claw 55 of the locking piece 53 is formed in the upper surface 81 of the member 34 so that the locking claw 55 is locked. Is done. In addition, such a configuration allows the gap 30 on the side wall 33 of the lid 30 to be formed in the gap 30 between the member 34 of the lid 30 and the upper wall 31 by forming the lid 30 at a deeper bottom. It is also realized by forming a through hole through which the locking piece 53 can be inserted. The through hole is a recess that is formed above the member 34 in the lid 30 and can accommodate at least a part of the other locking piece 53 of the lock member 50. Then, in a state where the main body 20 and the lid 30 are overlapped, the base portion of the locking piece 53 is accommodated in the through hole, and the tip portion including the locking claw 55 is located on the inner space 61 side of the protector 1. By being disposed so as to protrude, the locking piece 53 can come into contact with the member 34 from above the member 34, and the locking claw 55 can be locked to the member 34.

  Here, the protector 200 according to the comparative technique is provided with a lock portion 240 including a female lock portion 251 and a male lock portion 252 having a locking claw 253 formed at the tip (see FIG. 7). The female lock portion 251 is formed on the main body 220, and the male lock portion 252 is formed on the lid 230. In the protector 200, the male lock portion 252 is inserted into the hole of the female lock portion 251 in a state where the opening / closing direction of the main body 220 and the lid 230 matches the insertion / extraction direction of the male lock portion 252 with respect to the female lock portion 251. And the main body 220 and the lid | cover 230 are fixed when the latching claw 253 provided in the front-end | tip of the male locking part 252 and the frame part of the female locking part 251 contact | abut. For this reason, when the other member comes into contact with the locking claw 253 or when the protector 200 is twisted due to an external force acting, the locking claw 253 can be easily detached from the female lock portion 251 and the main body 220 and the lid 230 can be removed. The locked state is easily released. In order to prevent the locked state from being easily released, it is necessary to increase the area of the portion where the locking claw 253 and the frame of the female lock portion 251 come into contact with each other and to make the lock portion 240 difficult to twist. For this reason, the male lock portion 252 is increased in diameter, the width of the hole and the frame of the female lock portion 251 is increased, and the locking claw 253 is also increased in size. That is, the lock part 240 becomes large.

  On the other hand, in the protector 1, the locking piece 52 of the lock member 50 is placed on the lower side of the member 24 by fitting the lock member 50 to the members 24 and 34 in a state where the main body 20 and the lid 30 are overlapped. The locking piece 53 is disposed at a position where it can abut on the member 34 from above the member 34, and the locking pieces 52, 53 are connected to the member 24 and the member 24. The movement in the separation direction (vertical direction) with respect to 34 is restricted. In the restricted state, the locking claw 54 of the locking piece 52 locks the member 24 and the locking claw 55 of the locking piece 53 is locked so that the locking member 50 can be prevented from being detached from the members 24 and 34. The member 34 is locked.

  The movement of the member 24 and the member 34 in the separation direction is regulated by the locking pieces 52 and 53 that can contact the members 24 and 34 with a larger contact area than the locking claw. The movement of the member 24 and the member 34 in the separating direction can be more reliably regulated while reducing the size of the member 53. Further, the opening / closing direction (vertical direction, closing direction) of the lid 30 with respect to the main body 20, that is, the separation direction between the member 24 and the member 34, and the insertion direction (insertion direction, The insertion / extraction direction is different. As a result, even if a force acts in the direction in which the member 24 and the member 34 are separated from each other, the locking claws 54 and 55 are not detached from the members 24 and 34. It is possible to prevent the members 52 and 53 from coming off from the members 24 and 34. Therefore, in the protector 1, the main body 20 and the lid 30 can be more reliably fixed while downsizing the lock member 50. Furthermore, since the latching claws 54 and 55 can be reduced in size, the cross-sectional area of the inner space 61 of the protector 1 can be further increased.

  Further, in the protector 1, the main body 20 and the lid 30 are overlapped so that the lock member 50 faces the members 24 and 34, that is, the bottom surface of the groove portion 56 faces the members 24 and 34. The lock member 50 is pushed into the members 24 and 34 along the insertion direction (direction indicated by the arrow Y1) toward the member 34. Then, one locking piece 52 of the lock member 50 is inserted into the through hole 25 from the front, and the groove portion 56 and the members 24 and 34 are fitted. Therefore, for example, it is not necessary to fit the lock member 50 to the members 24 and 34 by sliding the lock member 50 from the ends of the members 24 and 34 in the extending direction of the members 24 and 34. As a result, the members 24 and 34 are set to have substantially the same length as the lock member 50, so that the size can be reduced. Further, when one locking piece 52 of the lock member 50 is not inserted into the through hole 25, the wire accommodated in the inner space 61 of the protector 1 from the opening 26 of the through hole 25 and the opening 36 of the recess 35. You can see the harness. Thereby, forgetting to attach the lock member 50 can be easily detected.

  As described above, in the protector 1, the main body 20 and the lid 30 can be easily locked while reducing the size of the outer peripheral surface, that is, the structure protruding from the outer peripheral surface 29 of the main body 20 and the outer peripheral surface 39 of the lid 30. It can be prevented from being released.

  In addition, as shown in FIG. 6, in the protector 200 according to the comparative technique, if the interference between the lock portion 250 and the external member is suppressed by narrowing the width itself, the inner space 261 of the protector 200 is disconnected. The area becomes smaller than the inner space 61 of the protector 1 according to the embodiment. Further, as in the case of the protector 100 according to the comparative technique, even if only the lock portion 150 is positioned inside the outer peripheral surface of the protector 100 in order to make the inner space larger, the inner space at the position of the lock portion 150 161 is smaller than the cross-sectional area of the inner space 61 of the protector 1 according to the embodiment. Thus, according to the protector 1, the cross-sectional area of the inner space 61 can be increased while suppressing the size of the structure protruding from the outer peripheral surface.

  According to the protector 1 according to this embodiment as described above, the one locking piece 53 of the lock member 50 is in front of the main body 20 and the lid 30 so that the lock member 50 faces the members 24 and 34. Therefore, the members 24 and 34 can be downsized to the same length as the lock member 50. Also, one locking piece 53 is disposed at a position where it can contact the member 24 from below the member 24, and the other locking piece 53 is disposed at a position where it can contact the member 34 from above the member 34. The locking claw 54 of the locking piece 52 is locked to the member 24 so that the locking of the locking member 50 can be prevented and the locking of the locking member 50 is prevented. Since the locking claw 55 of the piece 53 is locked to the member 34, the main body 20 and the lid 30 can be more reliably fixed while downsizing the locking member 50. Therefore, it is possible to prevent the lock state between the main body and the lid from being easily released while reducing the size of the structure protruding from the outer peripheral surface of the protector.

  Moreover, according to the protector 1 which concerns on this embodiment as mentioned above, the members 24 and 34 are inside the outer peripheral surfaces 29 and 39 of the main body 20 and the lid | cover 30 in the state with which the main body 20 and the lid | cover 30 were piled up. Therefore, the lock member 50 can be prevented from protruding from the outer peripheral surface of the protector 1. Therefore, the size of the structure protruding from the outer peripheral surface of the protector 1 can be further reduced.

  Further, according to the protector 1 according to this embodiment as described above, the outer peripheral surface 59 of the lock member 50 and the outer peripheral surfaces of the main body 20 and the lid 30 in a state where the main body 20 and the lid 30 are overlapped. Since 29 and 39 are flush with each other, the lock member 50 can be prevented from protruding from the outer peripheral surface of the protector 1. Therefore, the size of the structure protruding from the outer peripheral surface of the protector 1 can be further reduced.

  Moreover, according to the protector 1 which concerns on this embodiment as mentioned above, the recessed part 35 which can accommodate at least one part of the other latching piece 53 of the lock member 50 is further provided above the member 34 of the lid | cover 30, In a state where the main body 20 and the lid 30 are overlapped, at least a part of the locking piece 53 is accommodated in the concave portion 35 and disposed at a position where it can contact the member 34 from above the member 34. Therefore, the size of the structure protruding from the outer peripheral surface of the protector 1 can be reduced.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention. For example, in the protector 1, the main body 20 and the lid 30 are integrally formed of resin through the thin-walled hinge portion 49, but instead of the thin-walled hinge portion 49, the main body 20 and the lid 30 are similar to the members 24 and 34. A member may be further provided, and the main body 20 and the lid 30 may be fixed by a lock member similar to the lock member 50.
