In the following description, the shapes of the respective figures referred to are conceptual diagrams or schematic diagrams for explaining suitable shape dimensions, and the dimensional ratios etc. do not necessarily match the actual dimensional ratios. That is, the present invention is not limited to the dimensional ratios in the drawings. Also, the up-down, left-right directions in the present invention are merely concepts indicating relative positions, and it goes without saying that these can be interchanged and applied.

[0027] The tightening device of the present invention includes a locking body, a band body that extends in a band shape from the base end integrally connected to the locking body to the tip end forming a free end, and a locked portion is formed in a predetermined region in the longitudinal direction, and is for surrounding an object, and a locking mechanism for forming a locked state in which the locked portion of the band body is locked to the locking body. Hereinafter, the wiring and pipe material holder 100 will be described as the first embodiment according to the tightening device of the present invention, and the tightening band 200 will be described as the second embodiment. However, the description of the following embodiments is not intended to limit the present invention, and the features of the locking mechanism of the present invention can be applied to tightening devices for all uses that act to tighten an object.

[0028] [First Embodiment] The wiring and pipe material holder 100 according to an embodiment of the present invention is fixed to a structure such as a building material or a wall material, and is used for the purpose of arranging wiring and pipe materials with respect to the structure. In this embodiment, the structure to which the wiring and pipe material holder 100 is fixed is a building material having an installation surface 11 (or an arrangement surface) on one side surface, and the wiring and pipe material P is exemplified as a corrugated flexible pipe. The wiring and pipe material P is formed such that ridges (large-diameter portions) and valleys (small-diameter portions) are alternately continuous in the longitudinal direction. However, this embodiment is merely an example of the present invention, and it goes without saying that the use and configuration are not limited as long as they do not deviate from the technical scope of the present invention. Hereinafter, the configuration of the wiring and pipe material holder 100 of the present invention will be described.

[0029] Figs. 1(a) and (b) are perspective views of the wiring and pipe material holder 100 according to an embodiment of the present invention. Figs. 2(a) and (b) are a front view and a partially enlarged view of the wiring and pipe material holder 100. Figs. 3(a) to (d) are a plan view, a left side view, a right side view, and a bottom view of the wiring and pipe material holder 100. Figs. 4(a) and (b) are cross-sectional views taken along line A-A and line A'-A' of the wiring and pipe material holder 100. Fig. 5 is a cross-sectional view of the wiring and pipe material holder 100 in a locked state in which the annular space 101 is maintained by the band body 130 and the base 110.

[0030] As shown in Fig. 7 and the like, the wiring and pipe material holder 100 of the present embodiment is fixed to the installation surface 11 of the structure, and holds or grips the wiring and pipe material P in the annular space 101 as a holding portion, so that the wiring and pipe material P is arranged along the installation surface 11 in a predetermined arrangement direction. In the present embodiment, the wiring and pipe material holder 100 is integrally formed of synthetic resin and has flexibility and elasticity in a band-shaped formed portion. Here, the annular space 101 means a region in which the wiring and pipe material P having a predetermined diameter as a holding target is held, but can also be interpreted as a region in which the outer edge thereof varies according to the diameter (corresponding minimum diameter to opposing maximum diameter) of the wiring and pipe material P to be held.

[0031] The wiring and pipe material holder 100 of the present embodiment includes a base 110 fixed to the installation surface 11, a locked portion 133 formed in a predetermined region in the longitudinal direction, a band body 130 for surrounding the outer peripheral surface of the wiring and pipe material P in cooperation with the base 110, and a locking mechanism 150 for forming a locked state in which the locked portion 133 of the band body 130 is locked to the base 110 as a locking body. In the wiring and pipe material holder 100, the base 110, the band body 130, and the locking mechanism 150 are integrally formed. Here, the direction extending left and right on the bottom surface of the wiring and pipe material holder 100 is defined as the extending direction, the direction orthogonal to the extending direction on the same bottom surface (the arrangement direction of the wiring and pipe material P) is defined as the width direction, and the direction orthogonal to the extending direction and the width direction (the direction perpendicular to the bottom surface of the wiring and pipe material holder 100) is defined as the height direction. Hereinafter, each component of the wiring and pipe material holder 100 of the present embodiment will be described in detail.

[0032] The base 110 extends from one end on the right side to the other end on the left side when viewed from the front, and is formed as a block body that supports the wiring and piping material P and is fixed to the structure. The base 110 has a fixing portion 115 fixed to the installation surface 11 of the structure and a receiving portion 114 for receiving the wiring and piping material P arranged along the arrangement direction. Further, the base 110 includes a bottom wall portion 111 extending from one end to the other end, a first side wall portion 112 erected in the height direction on one end side of the bottom wall portion 111, and a second side wall portion 113 erected in the height direction on the other end side of the bottom wall portion 111. The base end of the band body 130 is connected to the top of the first side wall portion 112. Further, a locking mechanism 150 (insertion path 151, elastic locking piece 153, locking portion 154, release operation portion 155) for locking the locked portion of the band body 130 is provided on the second side wall portion 113.

[0033] The fixing portion 115 is a through hole formed through the bottom wall portion 111 between the first side wall portion 112 and the second side wall portion 113. Further, a fixing surface 116 fixed to the installation surface 11 is formed on the bottom surface of the bottom wall portion 111. By passing a screw through the fixing portion 115, the fixing surface 116 (bottom surface) of the base 110 can be brought into contact with and fixed to the installation surface 11 of the structure.

[0034] The receiving portion 114 is disposed above the bottom wall portion 111 in a predetermined region extending from one end side to the other end side, and is configured to receive the wiring and piping material P along the laying direction. In the present embodiment, the laying direction of the wiring and piping material P is the same as the width direction of the base 110. More specifically, in a front view, the receiving portion 114 extends between the first side wall portion 112 and the second side wall portion 113, and forms an arc-shaped recess for placing or gripping the wiring and piping material P. Further, the receiving portion 114 has a receiving surface for supporting the placed wiring and piping material P. This receiving surface faces the side opposite to the fixing surface 116 and has a concave curved surface shape in a front view. The receiving surface of the receiving portion 114 is spaced apart from the fixing surface 116 by a predetermined distance in the height direction, and the receiving portion 114 can be disposed with the wiring and piping material P separated from the installation surface 11. Furthermore, a recessed portion 117 is provided below the approximate center of the receiving portion 114 in a plan view. Through the recessed portion 117, the bottom wall portion 111 and the fixing portion 115 face above the receiving portion 114.

[0035] The band body 130 is a strip-shaped elongated body extending longitudinally from one end side of the base 110 by a predetermined length. FIG. 5 shows a wiring and piping material holder 100 in which the tip of the band body 130 is locked to the base 110 to form an annular space 101. As shown in FIG. 5, the band body 130 is freely flexible and deformable in the longitudinal direction, and cooperates with the receiving portion 114 of the base 110 to surround the outer peripheral surface of the wiring and piping material P, and is configured to form an annular space 101 that circumferentially surrounds the outer peripheral surface of the wiring and piping material P. This annular space 101 is defined by an annular outer peripheral line closed in the circumferential direction and has an opening surface that opens on both sides in the width direction (laying direction). The length of the band body 130 can be set according to the diameter (corresponding maximum diameter) of the wiring and piping material P to be held. Further, the band body 130 has an inner surface and an outer surface, and the inner surface is the surface facing the wiring and piping material P when the annular space 101 is formed.

[0036] The band body 130 is composed of a wide base end side portion 131 integrally connected to one end side of the base 110 and a narrow tip side portion 132 having a tip forming a free end. Here, the width of the base end side portion 131 is larger than the opening width of the inlet 151a of the insertion path 151, and the width of the tip side portion 132 is smaller than the opening width of the inlet 151a of the insertion path 151. That is, while the insertion of the tip side portion 132 of the band body 130 into the insertion path 151 is allowed, the insertion of the base end side portion 131 into the insertion path 151 is restricted.

[0037] The base end side portion 131 is formed to mainly grip the wiring and pipe material P. A plurality of protrusions 135 protruding substantially at the center in the width direction are formed on the inner surface of the base end side portion 131. By entering into the groove portion of the wiring and pipe material P and engaging with its outer surface, the plurality of protrusions 135 prevent the wiring and pipe material P from shifting in the laying direction.

[0038] The tip side portion 132 is configured to be inserted into the insertion path 151 on the other end side of the base 110 and locked by the locking mechanism 150. A locked portion 133 extending over most of the longitudinal direction is formed on the outer surface of the tip side portion 132. The locked portion 133 is composed of a locked tooth row composed of a plurality of locking teeth aligned in the longitudinal direction. Each locking tooth constituting the locked tooth row has an inclined surface on the tip side in the longitudinal direction of the band body 130 and has a sawtooth shape having a locking surface standing substantially perpendicular to the outer surface of the band body 130 on the opposite side. Further, at the tip of the tip side portion 132, a guide end portion 134 that is relatively thinner than the portion where the locked portion 133 is formed and has a rounded tip edge is provided. The guide end portion 134 can function as a guide portion when being introduced into the insertion path 151.

[0039] The locking mechanism 150 is provided on the second side wall portion 113 of the base 110, and forms a locked state in which the locked portion 133 of the band body 130 is locked to the other end side of the base 110 so as to maintain the annular space 101 that circumferentially surrounds the outer peripheral surface of the wiring and piping material P, and is configured to be able to tighten the wiring and piping material P within the annular space 101. And the locking mechanism 150 allows the movement of the band body 130 in the direction of reducing the annular space 101 (insertion direction) while maintaining the annular space 101, and functions to restrict the movement of the band body 130 in the direction of expanding the annular space 101 (anti-insertion direction).

[0040] As shown in FIGS. 4(a) and (b), the locking mechanism 150 is provided on the other end side of the base 110, and includes an insertion path 151 that extends to be able to insert the band body 130, an elastic locking piece 153 that locks the locked portion 133 of the band body 130 inserted into the insertion path 151, and a release operation portion 155 that can elastically displace the elastic locking piece 153 to release the locked state.

[0041] The insertion path 151 extends inside the wall of the second side wall portion 113 of the base 110 and is a passage formed to receive the band body 130 inside. The insertion path 151 has a slit-shaped inlet 151a formed on the top surface of the base 110 (second side wall portion 113) and extending in the width direction of the base 110, and an outlet 151b that opens facing the other end side near the bottom wall portion 111 of the base 110. The inlet 151a opens vertically upward with respect to the fixed surface 116. That is, when the fixing portion 115 is fixed to the installation surface 11 of the structure, the inlet 151a opens in a direction substantially perpendicular to the installation surface 11. Thereby, the inlet 151a can receive the tip of the band body 130 from a direction substantially perpendicular to the installation surface 11 or the fixed surface 116. On the other hand, the outlet 151b opens on the outer surface of the second side wall portion 113 on the other end side and also opens on the bottom surface side because the other end edge of the bottom wall portion 111 is notched. That is, the outlet 151b opens in both the other end side and the bottom surface side of the base 110. And the insertion path 151 extends in the insertion direction of the band body 130 from the inlet 151a to the outlet 151b.

[0042] In addition, the insertion path 151 continuously has a cross-sectional shape corresponding to the flat cross-section of the band body 130 in the insertion direction. In particular, the insertion path 151 includes a straight path extending substantially perpendicular from the inlet 151a toward the fixing surface 116, and a curved path curved in a direction away from the receiving portion 114 toward the other end side on the downstream side of the straight path. An elastic locking piece 153 is arranged on the other end side in the straight path of the insertion path 151. On the inner wall surface of one end side of the insertion path 151, a support surface 151c is provided on the side opposite to the elastic locking piece 153 and supports the band body 130 inserted into the insertion path 151 from the side opposite to the elastic locking piece 153. The support surface 151c is continuously formed before and after in the insertion direction at a position facing the elastic locking piece 153 (at least the locking portion 154). The support surface 151c acts to support the inner surface of the inserted band body 130 from the side opposite to the elastic locking piece 153. Further, a guide surface 151d forming a concave curved surface is formed on the inner wall surface of one end side of the curved path of the insertion path 151. The guide surface 151d abuts against the tip of the band body 130 inserted into the insertion path 151 and guides the tip of the band body 130 toward the outlet 151b in a direction away from the receiving portion 114 while facing the installation surface 11 (fixing surface 116).

[0043] The elastic locking piece 153 allows the movement of the band body 130 in the insertion direction in the locked state and acts to restrict the movement of the band body 130 in the removal direction (opposite insertion direction). More specifically, the elastic locking piece 153 is an elastically deformable rectangular plate extending along the insertion direction of the insertion path 151 from the top of the second side wall portion 113. The elastic locking piece 153 has a fixed end on the inlet 151a side, a free end on the outlet 151b side, and a front surface facing the insertion path 151. The elastic locking piece 153 is elastically deformable with its fixed end as a fulcrum. Also, a space (or gap) for allowing the displacement of the elastic locking piece 153 is provided on the rear surface side of the elastic locking piece 153 inside the base 110. That is, the elastic locking piece 153 is configured to elastically tilt in a direction away from the insertion path 151 (or the support surface 151c). And the elastic locking piece 153 has a locking portion 154 that engages with the locked portion 133 of the band body 130 inserted into the insertion path 151. The locking portion 154 protrudes into the insertion path 151 from the front surface of the elastic locking piece 153. And the elastic locking piece 153 is elastically displaceable in the proximity and separation direction for bringing the locking portion 154 closer to and separating it from the locked portion 133 (to be engaged) (see Fig. 6). That is, the displacement direction of the locking portion 154 is the proximity and separation direction of the locking portion 154 and the locked portion 133, and is the direction in which the locking portion 154 and the locked portion 133 form an engagement and release the engagement. Note that this displacement direction is a direction substantially orthogonal to the insertion direction.

[0044] The locking portion 154 is composed of one locking tooth (or locking claw) that protrudes into the insertion path 151 from the surface facing the insertion path 151 side of the elastic locking piece 153. As shown in FIG. 5, when the band body 130 is inserted into the insertion path 151, the locking portion 154 is disposed so as to face the locked portion 133 on the outer surface of the band body 130. In the original shape (without elastic deformation) of the elastic locking piece 153, the facing distance between the locking portion 154 and the support surface 151c is smaller than the thickness including the protruding height of the locking teeth of the locked portion 133 of the band body 130. In particular, it is preferable that the facing distance between the locking portion 154 and the support surface 151c is smaller than the thickness not including the protruding height of the locking teeth of the locked portion 133 of the band body 130. In the locked state shown in FIG. 5, due to the elastic restoring force of the elastic locking piece 153, it becomes possible to sandwich the band body 130 between the locking portion 154 and the support surface 151c.

[0045] Further, the locking portion 154 has an inclined surface on the inlet 151a side of the insertion path 151, and has a sawtooth shape having a locking surface standing substantially perpendicular to the elastic locking piece 153 on the opposite side. When the tip-side portion 132 of the band body 130 is inserted to a predetermined position in the insertion path 151, the locking portion 154 engages with each locking tooth of the locked portion 133 with a click. At this time, by the sliding contact between the inclined surfaces of the locking teeth, relative movement in the direction of advancing the band body 130 in the insertion direction and reducing the annular space 101 is allowed. When the band body 130 is advanced in the insertion direction, the elastic locking piece 153 is elastically deformed, so that the locking portion 154 can overcome each locking tooth of the locked portion 133. On the other hand, by locking the locking surfaces of the locking teeth to each other, relative movement in the direction of retreating the band body 130 in the detachment direction and expanding the annular space 101 is restricted. Further, when the elastic locking piece 153 is elastically displaced relatively in the direction in which the locking portion 154 and the locked portion 133 are relatively separated, the locked state by both locking teeth is released.

[0046] The release operation portion 155 is formed to protrude to the outside on both sides in the width direction of the base 110 (the second side wall portion 113) so that the elastic locking piece 153 can be elastically displaced to release the locked state. The release operation portion 155 is formed as a knob that protrudes at a position and by an amount that can be operated by a user's hand, an operating tool, or the like. In particular, as shown in FIGS. 3 and 4(b), the release operation portion 155 protrudes linearly without bending from the elastic locking piece 153, and is a rectangular protruding piece integrally protruding from both end faces in the width direction of the elastic locking piece 153. And the release operation portion 155 extends outward in the width direction of the insertion path 151 in a direction intersecting (or orthogonal to) both the insertion direction of the insertion path 151 and the displacement direction of the locking portion 154. In other words, the release operation portion 155 protrudes along an intersection axis intersecting the opening surface of the annular space 101. In the present embodiment, the protruding direction of the release operation portion 155 coincides with the arrangement direction of the wiring and pipe material P. Here, on the outer surfaces on both sides in the width direction of the base 110, open portions 156 communicating with the insertion path 151 are formed to penetrate. That is, the release operation portion 155 extends out from the base 110 through the open portion 156 and is exposed as a knob in the external space. The open portion 156 has a shape that allows at least relative movement (displacement) of one end side of the release operation portion 155 in the open portion 156 in accordance with displacement in the separation (engagement / disengagement) direction of the engaged portion 133 of the locking portion 154.

[0047] Based on the description of each of the above components, with reference to FIGS. 5 and 6, the locked state and the unlocking of the wiring and pipe material holder 100 will be described.

[0048] FIG. 5 shows the wiring and pipe material holder 100 in a locked state in which the band body 130 is locked to the base 110 so as to maintain the annular space 101 surrounding the target (wiring and pipe material P) in the circumferential direction. As shown in FIG. 5, an annular space 101 is formed as a holding portion for holding the wiring and pipe material P inside the receiving portion 114 and the inner surface of the band body 130. Then, the tip of the band body 130 connected to one end of the base 110 is fixed to the other end of the base 110 by the locking mechanism 150, so that the annular space 101 is closed in the circumferential direction.

[0049] More specifically, the band body 130 is bent and deformed from its initial position shown by the phantom line in FIG. 5, spans from one end of the receiving portion 114 to the other end, and its tip is inserted into the insertion path 151 through the introduction port 151a. Then, the tip side portion 132 of the band body 130 is inserted into the insertion path 151, and the locked portion 133 is disposed facing the locking portion 154 of the elastic locking piece 153, meshing with each other. At this time, the band body 130 is sandwiched between the top surface of the locking portion 154 and the support surface 151c of the insertion path 151. And due to the meshing of the locked portion 133 and the locking portion 154, a locking state is formed that allows the band body 130 to move in the insertion direction and restricts the movement of the band body 130 in the detachment direction.

[0050] Furthermore, the band body 130 is bent and deformed along the insertion direction in the insertion path 151 according to the shape of the insertion path 151. That is, the band body 130 extends linearly in the straight path facing the elastic locking piece 153, and bends in accordance with the curve of the guide surface 151d in the curved path on its downstream side (the outlet port 151b side). And the tip of the band body 130 extends out of the base 110 from the outlet port 151b that opens toward the other end side.

[0051] As shown in FIG. 6, by applying a force to the release operation portion 155 that protrudes in the width direction from the base 110 in the direction of the other end side that is separated from the receiving portion 114, the elastic locking piece 153 tilts in the direction of separating from the insertion path 151. At this time, the release operation portion 155 extends in a direction intersecting the insertion direction of the insertion path 151 (the extending direction of the band body 130 that forms the locked state), and does not overlap with the band body 130 arranged in a ring shape in the circumferential direction, so the operation is not obstructed by the band body 130. Further, since the protruding direction of the release operation portion 155 also intersects the displacement direction of the locking portion 154, the user can hook a finger or the like on the knob from the space on the side of the elastic locking piece 153 and operate it, so the unlocking operation is easy. That is, by operating the release operation portion 155, a release state is easily formed in which the locking portion 154 is displaced so as to be separated (or engaged and disengaged) from the locked portion 133. In this unlocked state, since the locking portion 154 does not contact the locked portion 133, the band body 130 can move freely in both the insertion direction and the detachment direction within the insertion path 151. Then, while maintaining the unlocked state, by moving the band body 130 in the advancing and retreating directions, it is possible to pull out the band body 130 from the insertion path 151 or adjust the size of the annular space 101 to expand.

[0052] Next, with reference to FIGS. 7 to 9, the installation structure 10 in which the wiring and pipe material holder 100 of the present embodiment holds and arranges the wiring and pipe material P having a relatively small diameter with respect to the installation surface 11 of the construction material (structure) will be described. FIG. 7 is a schematic perspective view of the installation structure 10. FIG. 8 is a schematic front view of the installation structure 10. FIG. 9 is a cross-sectional view taken along line B-B of the installation structure 10.

[0053] As shown in FIGS. 7 and 8, in the installation structure 10 of the present embodiment, the structure is a wall-shaped construction material that stands vertically, and the wiring and pipe material holder 100 is fixed to the installation surface 11 facing the front of the construction material. Then, the wiring and pipe material P is gripped by the wiring and pipe material holder 100, and its arrangement direction is arranged along the vertical direction.

[0054] As shown in Fig. 9, in the installation structure 10, after the fixing surface 116 of the base 110 of the wiring and pipe material holder 100 abuts against the installation surface 11, the screw 15 penetrates the fixing portion 115 of the bottom wall portion 111, whereby the wiring and pipe material holder 100 is fixed to the installation surface 11. At this time, the head of the screw 15 is accommodated in the recessed portion 117, and the shaft portion is screwed into the installation surface 11. The wiring and pipe material holder 100 is fixed in a posture where its width direction is along the vertical direction.

[0055] In the installation structure 10, the wiring and pipe material P is held in the closed annular space 101 of the wiring and pipe material holder 100. As shown in Fig. 9, the band body 130 is locked by the locking mechanism 150 of the base 110, whereby the closed state of the annular space 101 is maintained. And the wiring and pipe material P is sandwiched between the inner surface of the band body 130 and the curved surface of the receiving portion 114. Also, the band body 130 cooperates with the base 110 to firmly clamp the outer peripheral surface of the wiring and pipe material P. In this locked state, loosening of the clamping of the wiring and pipe material P is regulated. At this time, the protrusion 135 on the inner surface of the band body 130 enters the trough portion of the wiring and pipe material P, preventing displacement of the wiring and pipe material P in the laying direction.

[0056] Also, in the installation structure 10, the band body 130 is inserted into the insertion path 151 and locked until it strongly wraps around the outer peripheral surface of the wiring and pipe material P. And the tip of the band body 130 extends outside from the outlet 151b of the insertion path 151. At this time, since the tip of the band body 130 extends toward the other end side of the base 110 so as to be away from the receiving portion 114, it does not interfere with the installation surface 11 and the wiring and pipe material P. Therefore, cutting of the tip of the band body 130 is unnecessary.

[0057] FIG. 10 is a schematic cross-sectional view of an installation structure 10 in which a wiring and pipe material holder 100 according to the present embodiment holds and arranges a wiring and pipe material P having a relatively large diameter with respect to an installation surface 11. As shown in FIG. 10, when the band body 130 is locked by the locking mechanism 150 of the base 110, the closed state of the annular space 101 is maintained. Then, the band body 130 cooperates with the base 110 to firmly clamp the outer peripheral surface of the wiring and pipe material P. In the installation structure 10, since the wiring and pipe material P has a relatively large diameter, the tip of the band body 130 stays inside the insertion path 151 and does not extend outside from the lead-out port 151b. Even in this form, the locking state is formed by the engagement of the locking portion 154 and the locked portion 133. That is, depending on the size of the object to be clamped (the diameter of the wiring and pipe material), the tip of the band body 130 does not need to extend from the insertion path 151. Therefore, in the present invention, the outlet of the insertion path 151 may be closed.

[0058] Subsequently, a method for constructing the installation structure 10 using the wiring and pipe material holder 100 according to the present embodiment will be described. First, the wiring and pipe material holder 100 is fixed to a predetermined fixed position on the installation surface 11 of the construction material. While aligning the fixing surface 116 of the wiring and pipe material holder 100 with the installation surface 11, the position of the wiring and pipe material holder 100 is determined, and its posture is maintained so as to define the laying direction of the wiring and pipe material P. Then, a screw 15 is inserted into the fixing portion 115 from the front. Then, by operating a tool (driver) to screw the screw 15 into the installation surface 11, the wiring and pipe material holder 100 can be fixed to the installation surface 11.

[0059] Next, the wiring and pipe material P is grasped by aiming at the receiving part 114. Then, the band body 130 is bent and deformed so as to be wound around the outer peripheral surface of the wiring and pipe material P, and the tip of the band body 130 is inserted into the inlet 151a of the insertion path 151. At this time, since the inlet 151a is open in a direction substantially perpendicular to the installation surface 11, the user can easily insert the tip of the band body 130 toward the outlet 151b from the front of the installation surface 11. Next, the band body 130 is fed into the insertion path 151, the engaged part 133 and the locking part 154 are engaged to form a locked state by the locking mechanism 150. While changing the locking positions of the locking part 154 and the engaged part 133 toward the proximal end side of the band body 130 until the outer peripheral surface of the wiring and pipe material P is strongly tightened by the band body 130, the band body 130 is advanced along the insertion direction, whereby the wiring and pipe material P can be grasped by the receiving part 114 and the band body 130. When holding a wiring and pipe material P with a relatively small diameter, the wiring and pipe material P can be easily and firmly tightened by pulling the tip of the band body 130 extending from the outlet 151b of the insertion path 151.

[0060] In the installation structure 10, to loosen the tightening of the wiring and pipe material P or to open the annular space 101, the locking state by the locking mechanism 150 may be released by moving the release operation part 155 as described above. The user can pinch a pair of release operation parts 155 protruding from the side space (in the radial direction) of the wiring and pipe material P toward both sides in the installation direction (not necessarily parallel to the installation direction) with fingers from both sides and move them in a direction away from the wiring and pipe material P to be tightened (toward the front side of the user), thereby displacing the locking part 154 in the same direction and easily releasing the locked state. Further, as an example of a method for releasing the locked state, an operation tool T may be used. A method for releasing using the operation tool T will be described below with reference to FIGS. 11 and 12. In FIGS. 11 and 12, a wiring and pipe material P with a relatively large diameter similar to that in FIG. 10 is depicted.

[0061] As shown in Fig. 11, the user can operate an operating tool T having a thin tip shaft such as a minus driver, and elastically displace the elastic locking piece 153 through the release operation portion 155 of the wiring and pipe material holder 100, thereby releasing the locking state between the locking portion 154 and the locked portion 133. The operation of the operating tool T is performed in a direction orthogonal to the laying direction of the wiring and pipe material P, and is carried out from the space on the front side of the installation surface 11 of the building material. That is, the user can operate the operating tool T using the wider space on the front side of the wiring and pipe material P, and can perform the unlocking more easily. This method is effective in a situation where an obstacle such as a wall is installed on the other end side of the wiring and pipe material holder 100 (the direction in which the locking portion 154 separates from the locked portion 133), the space on the side of the wiring and pipe material P is narrow, and it is difficult to operate by pinching and moving the release operation portion 155 with a finger. Further, since the release operation portion 155 protrudes in the laying direction on the side portion of the wiring and pipe material P and forms a gap that opens in a direction different from the pipe axis (direction) of the wiring and pipe material P, it is not necessary to perform the release operation with the operating tool T along the pipe axis (the operating tool T interferes with the wiring and pipe material P and is difficult to operate). That is, the wiring and pipe material holder 100 of the present embodiment has higher workability.

[0062] Referring to Fig. 12, the release operation using the operating tool T will be described in more detail. First, the tip of the operating tool T is inserted into the gap between the outer peripheral surface of the wiring and pipe material P and the release operation portion 155 extending opposite thereto. Next, as shown in Fig. 12(a), the operating tool T is brought into contact with two points, i.e., the outer peripheral surface of the wiring and pipe material P and the release operation portion 155. With the contact point with the outer peripheral surface of the wiring and pipe material P as the fulcrum and the contact point with the release operation portion 155 as the acting point, the operating tool T is tilted and operated in the circumferential direction of the wiring and pipe material P (see the arrow in Fig. 12(a)). Then, as shown in Fig. 12(b), the release operation portion 155 can be moved radially outward of the wiring and pipe material P at the tip of the operating tool T, thereby releasing the locking state between the locking portion 154 and the locked portion 133.

[0063] That is, the wiring and pipe material holder 100 of the present embodiment also has the following features. The elastic locking piece 153 is provided with a release operation portion 155 that projects in the arrangement direction so as to face the outer peripheral surface of the wiring and pipe material P to be held with a gap therebetween. The gap has a size that allows an operation tool T to be inserted between the outer peripheral surface of the wiring and pipe material P held in the annular space 101 and the release operation portion 155. When the operation tool T is inserted into the gap, the proximal end side of the operation tool T is brought into contact with the outer peripheral surface of the wiring and pipe material P, and the distal end side of the operation tool T is brought into contact with the release operation portion 155. With the outer peripheral surface of the wiring and pipe material P as a fulcrum and the release operation portion 155 as a point of action, when the operation tool T is tilted, the release operation portion 155 moves so as to separate from the wiring and pipe material P, and the locking portion 154 relatively moves in a direction away from the locked portion 133 of the band body 130.

[0064] Hereinafter, the effects of the wiring and pipe material holder 100 according to an embodiment of the present invention will be described.

[0065] According to the wiring and pipe material holder 100 of the present embodiment, the release operation portion 155 protrudes from the elastic locking piece 153 to the outside of the insertion path 151 in a direction intersecting the insertion direction of the insertion path 151 provided in the base 110. And the release operation portion 155 can elastically displace the elastic locking piece 153 to release the locked state. That is, since the release operation portion 155 is not provided in the same direction with respect to the band body 130, when the user operates the release operation portion 155 with a finger or an operation tool to release the lock, the lock release operation can be performed without being obstructed by the band body 130. Further, the release operation portion 155 is a knob protruding in a direction intersecting the displacement direction of the locking portion 154 along with the insertion direction of the insertion path 151. Thereby, the user can use the space on the side of the elastic locking piece 153 (or the space on the side where the release operation portion 155 protrudes) to hook a finger or an operation tool on the knob and easily move the release operation portion 155 in the displacement direction of the locking portion 154. In particular, the operation in the direction away from the wiring and pipe material P to be held becomes the lock release, which is intuitive and easy to perform, and has better workability than approaching. Further, since the release operation portion 155 protrudes linearly from the elastic locking piece 153 without bending, the movement of the knob due to the release operation can be directly transmitted to the elastic locking piece 153. Therefore, the wiring and pipe material holder 100 of the present embodiment facilitates the lock release operation.

[0066] [Second Embodiment] The tightening band 200 of the second embodiment of the present invention is for tightening in an annular space 201 that surrounds the outer peripheral surface of an object in the circumferential direction. For example, the tightening band 200 can be used for the purpose of binding wiring and pipe materials P and the like. In the present embodiment, the tightening band 200 is integrally formed of a synthetic resin and has flexibility at the portion formed in a band shape. Here, the annular space 201 means a region surrounding the object to be tightened, but can also be interpreted as a region where its outer edge fluctuates according to the outer peripheral shape of the object. In the following description, the object to be tightened is exemplified as the wiring and pipe material P.

[0067] Figs. 13(a) and (b) are a perspective view and a partially enlarged view of a fastening band 200 according to an embodiment of the present invention. Figs. 14(a) to (c) are a front view and a partially enlarged view of the fastening band 200. Figs. 15(a) to (d) are a plan view, a left side view, a right side view, and a bottom view of the fastening band 200. Figs. 16(a) and (b) are a C-C sectional view and a C'-C' sectional view of the fastening band 200.

[0068] The fastening band 200 of the present embodiment includes a locking body 210, a band body 230 in which a locked portion 233 is formed in a predetermined region in the longitudinal direction and which cooperates with the locking body 210 to surround the outer peripheral surface of an object, and a locking mechanism 250 for forming a locked state in which the locked portion of the band body 230 is locked to the locking body 210. In the fastening band 200, the locking body 210, the band body 230, and the locking mechanism 250 are integrally formed. Note that the locking mechanism 250 has technical features in common with the locking mechanism 150 of the fastening band 200. Here, the direction extending left and right on the bottom surface of the fastening band 200 is defined as the extending direction, the direction orthogonal to the extending direction on the same bottom surface is defined as the width direction, and the direction orthogonal to the extending direction and the width direction is defined as the height direction. Hereinafter, each component of the fastening band 200 of the present embodiment will be described in detail.

[0069] The locking body 210 is formed as a housing having a hollow portion. The locking body 210 includes a bottom wall 211 extending from one end on the right side in the front view to the other end on the left side, a peripheral wall 212 erected from the periphery of the bottom wall 211, and a top wall 213 facing the bottom wall 211. The proximal end of the band body 230 is connected to one end edge of the top wall 213 (or the top portion on one end side of the peripheral wall 212). Further, the locking body 210 is provided with a locking mechanism 250 (insertion path 251, elastic locking piece 253, locking portion 254, release operation portion 255) to which the locked portion of the band body 230 is locked.

[0070] The band body 230 is a strip-shaped elongated body that extends longitudinally from one end side of the locking body 210 by a predetermined length. FIG. 17 shows a tightening band 200 in which the tip of the band body 230 is locked to the locking body 210 to form an annular space 201 that surrounds the object (here, the wiring and piping material P). As shown in FIG. 17, the band body 230 is freely flexible and deformable in the longitudinal direction, and is configured to cooperate with the locking body 210 to surround the outer peripheral surface of the wiring and piping material P and form an annular space 201 that circumferentially surrounds the outer peripheral surface of the wiring and piping material P. This annular space 201 is defined by an annular outer peripheral line that is closed in the circumferential direction and has an opening surface that opens on both sides in the width direction. The length of the band body 230 can be set according to the outer peripheral shape of the object to be tightened. Further, the band body 230 has an inner surface and an outer surface, and the inner surface is the surface that faces the object when forming the annular space 201.

[0071] The band body 230 includes a base end side portion 231 integrally connected to one end side of the locking body 210 and a tip end side portion 232 having a tip end that forms a free end. Here, a locked portion 233 is not formed on the outer surface of the base end side portion 231, and a locked portion 233 is formed on the outer surface of the tip end side portion 232.

[0072] The tip end side portion 232 is configured to be inserted into the insertion path 251 of the locking body 210 and locked by the locking mechanism 250. A locked portion 233 that extends over most of the longitudinal direction is formed on the outer surface of the tip end side portion 232. The locked portion 233 is composed of a locked tooth row including a plurality of locking teeth aligned in the longitudinal direction. Each locking tooth constituting the locked tooth row 223 has an inclined surface on the tip end side in the longitudinal direction of the band body 230 and a locking surface that stands substantially perpendicular to the outer surface of the band body 230 on the opposite side, forming a serrated shape. Further, at the tip of the tip end side portion 232, a guide end portion 234 that is relatively thinner than the portion where the locked portion 233 is formed and has a tapered tip is provided. The guide end portion 234 can function as a guide portion when being introduced into the insertion path 251.

[0073] The locking mechanism 250 is provided on the locking body 210 and forms a locked state in which the locked portion 233 of the band body 230 is locked to the locking body 210 so as to maintain an annular space 201 that circumferentially surrounds the outer peripheral surface of the object, and is configured to be able to clamp the object within the annular space 201. Then, the locking mechanism 250 allows the band body 230 to move in the direction of reducing the annular space 201 (insertion direction) while maintaining the annular space 201, and functions to restrict the movement of the band body 230 in the direction of expanding the annular space 201 (anti-insertion direction).

[0074] As shown in FIGS. 16(a) and (b), the locking mechanism 250 is provided on the other end side of the locking body 210 with respect to the base end of the band body 230, and includes an insertion path 251 that extends between the bottom wall 211 and the top wall 213 so as to allow the band body 230 to be inserted, an elastic locking piece 253 that locks the locked portion 233 of the band body 230 inserted into the insertion path 251, and a release operation portion 255 that elastically displaces the elastic locking piece 253 to enable a release operation of the locked state.

[0075] The insertion path 251 is a passage that extends so as to penetrate the locking body 210 in the height direction and is formed to receive the band body 230 therein. The insertion path 251 has a slit-shaped inlet 251a formed in the bottom wall 211 of the locking body 210 and extending in the width direction of the locking body 210, and a slit-shaped outlet 251b formed in the top wall 213 of the locking body 210 and extending in the width direction of the locking body 210. The inlet 251a and the outlet 251b are open in the height direction. Further, the inlet 251a is disposed on the side opposite to the side where the band body 230 extends from the locking body 210 and can receive the tip of the band body 230. And the insertion path 251 extends in the insertion direction of the band body 230 from the inlet 251a toward the outlet 251b. Note that the inlet 251a and the outlet 251b are provided on the other end side (circumferentially outer side of the annular space 201) of the locking body 210 with respect to the base end of the band body 230. Thereby, the tip portion of the band body 230 drawn out from the outlet 251b of the insertion path 251 is disposed on the radially outer side of the portion surrounding the annular space 201.

[0076] Further, the insertion path 251 continuously has a cross-sectional shape corresponding to the flat cross-section of the band body 230 in the insertion direction. The insertion path 251 consists of a straight path extending from the inlet 251a to the outlet 251b. An elastic locking piece 253 is arranged on the other end side of the insertion path 251. On the other hand, on the inner wall surface of one end side of the insertion path 251, a support surface 251c is provided which is located on the side opposite to the elastic locking piece 253 and supports the band body 230 inserted into the insertion path 251 from the opposite side of the elastic locking piece 253. The support surface 251c is continuously formed before and after in the insertion direction at a position facing the elastic locking piece 253 (at least the locking portion 254). The support surface 251c acts to support the inner surface of the inserted band body 230 from the opposite side of the elastic locking piece 253.

[0077] The elastic locking piece 253 acts to allow the movement of the band body 230 in the insertion direction in the locked state and restrict the movement of the band body 230 in the detachment direction (reverse insertion direction). More specifically, the elastic locking piece 253 is an elastically deformable rectangular plate extending along the insertion direction of the insertion path 251 from the bottom wall 211 of the locking body 210. The elastic locking piece 253 has a fixed end on the inlet 251a side, a free end on the outlet 251b side, and a front surface facing the insertion path 251. The elastic locking piece 253 is elastic with its fixed end as a fulcrum. Also, on the rear surface side of the elastic locking piece 253 inside the locking body 210, a space (or gap) for allowing the displacement of the elastic locking piece 253 is provided. That is, the elastic locking piece 253 is configured to elastically tilt in a direction away from the insertion path 251 (or the support surface 251c). And the elastic locking piece 253 has a locking portion 254 that engages with the locked portion 233 of the band body 230 inserted into the insertion path 251. The locking portion 254 protrudes into the insertion path 251 from the front surface of the elastic locking piece 253. And the elastic locking piece 253 is elastically displaceable in the approaching and separating direction for approaching and separating the locking portion 254 from the locked portion 233 (to be engaged) (see FIG. 20). That is, the displacement direction of the locking portion 254 is the approaching and separating direction of the locking portion 254 and the locked portion 233, and is the direction in which the locking portion 254 and the locked portion 233 form an engagement and release the engagement. Note that this displacement direction is a direction substantially orthogonal to the insertion direction.

[0078] The locking portion 254 is composed of one locking tooth (or locking claw) that protrudes into the insertion path 251 from the surface facing the insertion path 251 side of the elastic locking piece 253. As shown in FIG. 18, when the band body 230 is inserted into the insertion path 251, the locking portion 254 is arranged to face the locked portion 233 on the outer surface of the band body 230. In the original shape (without elastic deformation) of the elastic locking piece 253, the facing distance between the locking portion 254 and the support surface 251c is smaller than the thickness including the protruding height of the locking teeth of the locked portion 233 of the band body 230. In particular, it is preferable that the facing distance between the locking portion 254 and the support surface 251c is smaller than the thickness excluding the protruding height of the locking teeth of the locked portion 233 of the band body 230. In the locked state shown in FIG. 18, due to the elastic restoring force of the elastic locking piece 253, it is possible to sandwich the band body 230 between the locking portion 254 and the support surface 251c.

[0079] Further, the locking portion 254 has an inclined surface on the inlet 251a side of the insertion path 251, and has a sawtooth shape with a locking surface standing substantially vertically from the elastic locking piece 253 on the opposite side. When the tip-side portion 232 of the band body 230 is inserted to a predetermined position in the insertion path 251, the locking portion 254 engages slightly with each locking tooth of the locked portion 233. At this time, due to the sliding contact between the inclined surfaces of the locking teeth, relative movement of the band body 230 in the direction of advancing in the insertion direction and reducing the annular space 201 is allowed. When the band body 230 advances in the insertion direction, the elastic locking piece 253 elastically deforms, so that the locking portion 254 can overcome each locking tooth of the locked portion 233. On the other hand, when the locking surfaces of the locking teeth are locked to each other, relative movement of the band body 230 in the direction of retreating in the detachment direction and expanding the annular space 201 is restricted. Further, when the elastic locking piece 253 elastically displaces relatively in the direction in which the locking portion 254 and the locked portion 233 are relatively separated, the locked state by both locking teeth is released.

[0080] The unlocking operation portion 255 is formed to project outward on both sides in the width direction of the locking body 210 (peripheral wall 212) so that the elastic locking piece 253 can be elastically displaced to unlock the locked state. The unlocking operation portion 255 is formed as a knob that protrudes at a position and by an amount that allows a user to operate it with a hand, an operating tool, or the like. In particular, as shown in FIGS. 15 and 16(b), the unlocking operation portion 255 is a rectangular protruding piece integrally protruding from both end faces in the width direction of the elastic locking piece 253. And the unlocking operation portion 255 extends outward in the width direction of the insertion path 251 in a direction intersecting (or orthogonal to) both the insertion direction of the insertion path 251 and the displacement direction of the locking portion 254. In other words, the unlocking operation portion 255 protrudes along an intersection axis intersecting the opening surface of the annular space 201. Here, on the outer surfaces on both sides in the width direction of the peripheral wall 212 of the locking body 210, open portions 256 communicating with the insertion path 251 are formed through. That is, the unlocking operation portion 255 extends out from the locking body 210 through the open portion 256 and is exposed as a knob in the external space. The open portion 256 has a shape that allows at least relative movement (displacement) of one end side of the unlocking operation portion 255 within the open portion 256 in accordance with displacement in the separation (engagement / disengagement) direction of the locked portion 233 of the locking portion 254.

[0081] Based on the description of each of the above components, with reference to FIGS. 17 to 20, the locked state of the tightening band 200 and its unlocking will be described. FIGS. 17 and 18 are cross-sectional views schematically showing the tightening band 200 in a locked state in which the band body 230 is locked to the locking body 210 so as to maintain the annular space 201 surrounding the object (wiring / wiring pipe material P) in the circumferential direction. FIGS. 19 and 20 are cross-sectional views schematically showing the tightening band 200 in an unlocked state in which the locked state of FIGS. 17 and 18 is released.

[0082] As shown in FIG. 17, an annular space 201 is formed as a holding portion for tightening and holding the object inside the locking body 210 and the inner surface of the band body 230. And the tip of the band body 230 connected to one end of the locking body 210 is fixed by the locking mechanism 250 of the locking body 210, so that the annular space 201 is closed in the circumferential direction.

[0083] More specifically, the band body 230 is bent and deformed into an annular shape in accordance with the shape of the outer peripheral surface of the wiring and pipe material P from its initial position, and after being wound around substantially the entire outer peripheral surface of the wiring and pipe material P, it passes through the introduction port 251a and is inserted into the insertion path 251. Further, the tip of the band body 230 extends out from the discharge port 251b to the outside of the locking body 210. Then, the tip-side portion 232 of the band body 230 is inserted into the insertion path 251, and the locked portion 233 is disposed facing the locking portion 254 of the elastic locking piece 253, thereby meshing with each other. At this time, the band body 230 is sandwiched between the top surface of the locking portion 254 and the support surface 251c of the insertion path 251. And by the meshing of the locked portion 233 and the locking portion 254, a locking state is formed that allows the band body 230 to move in the insertion direction and restricts the movement of the band body 230 in the detachment direction. In this locking state, loosening of the tightening of the wiring and pipe material P is restricted.

[0084] As shown in FIGS. 19 and 20, by applying a force to the release operation portion 255 that protrudes in the width direction from the locking body 210 in the direction of the other end side (radial outer side) that is separated from the wiring and pipe material P (or the annular space 201), the elastic locking piece 253 tilts in the direction of separating from the insertion path 251. At this time, the release operation portion 255 extends in a direction intersecting the insertion direction of the insertion path 251 (the extending direction of the band body 230 that forms the locked state), and does not overlap with the circumferential direction of the annularly arranged band body 230, so the operation is not obstructed by the band body 230. Further, since the protruding direction of the release operation portion 255 also intersects the displacement direction of the locking portion 254, the user can hook a finger or the like on the knob from the space on the side of the elastic locking piece 253 and operate it, so the unlocking operation is easy. That is, by operating the release operation portion 255, a locking release state is easily formed in which the locking portion 254 is displaced so as to be separated (or disengaged) from the locked portion 233. In this locking release state, since the locking portion 254 does not contact the locked portion 233, the band body 230 can move freely in both the insertion direction and the detachment direction within the insertion path 251. Then, while maintaining the locking release state, by moving the band body 230 in the advancing and retreating directions, it is possible to pull out the band body 230 from the insertion path 251 or adjust to expand the size of the annular space 201. As shown in FIGS. 11 and 12, it is also possible to perform the unlocking operation by inserting the operation tool T into the gap between the release operation portion 255 and the wiring and pipe material P.

[0085] Hereinafter, the operation and effect of the tightening band 200 according to an embodiment of the present invention will be described.

[0086] According to the tightening band 200 of the present embodiment, the release operation portion 255 protrudes from the elastic locking piece 253 to the outside of the insertion path 531 in a direction intersecting the insertion direction of the insertion path 251 provided in the locking body 210. And the release operation portion 255 can elastically displace the elastic locking piece 253 to release the locked state. That is, since the release operation portion 255 is not provided in the same direction with respect to the band body 230, when the user operates the release operation portion 255 with a finger or an operating tool to release the lock, the release operation can be performed without being obstructed by the band body 230. Further, the release operation portion 255 is a knob protruding in a direction intersecting the displacement direction of the locking portion 254 along with the insertion direction of the insertion path 251. Thereby, the user can use the space on the side of the elastic locking piece 253 (or the space on the side where the release operation portion 255 protrudes) to hook a finger or an operating tool on the knob and easily move the release operation portion 255 in the displacement direction of the locking portion 254. In particular, the operation in the direction away from the object to be tightened becomes the unlocking, which is intuitive and easy to perform, and has better workability than approaching. Further, since the release operation portion 255 protrudes linearly without bending from the elastic locking piece 253, the movement of the knob due to the release operation can be directly transmitted to the elastic locking piece 253. Therefore, the tightening band 200 of the present embodiment makes the unlocking operation easier.

[0087] [Modification Example] The present invention is not limited to the above embodiment and can take various modification examples. Hereinafter, modification examples of the present invention will be described.

[0088] (1) The clamping device and the locking mechanism of the present invention are not limited to the configuration of the above embodiment. In the locking mechanism of the above embodiment, the release operation portion projects from the elastic locking piece to the outside of the insertion path in a direction intersecting both the insertion direction of the insertion path and the displacement direction of the locking portion. However, the present invention is not limited to this. That is, the release operation portion of the present invention only needs to project from the elastic locking piece to the outside of the insertion path at least in a direction intersecting the insertion direction of the insertion path. For example, FIG. 21 shows a clamping band 300 including a locking mechanism 350 according to a modification of the present invention. The clamping band 300 is a modification of the clamping band 200 of the second embodiment. Components with the same last two digits in the components indicated by three digits have the same or similar features and the description thereof will be partially omitted unless otherwise described.

[0089] In this tightening band 300, the locking mechanism 350 is provided on the locking body 310 and has an insertion path 351 into which the band body 330 can be inserted from the tip, and a locking portion 354 that engages with the locked portion 333 of the band body 330 inserted into the insertion path 351. The locking portion 354 is elastically displaceable in a direction away from the locked portion 333, and in the locked state, it allows the band body 330 to move in the insertion direction and restricts the movement of the band body 330 in the removal direction. It includes an elastic locking piece 353, and a release operation portion 355 that protrudes from the elastic locking piece 353 to the outside of the insertion path 351 in a direction intersecting the insertion direction of the insertion path 351, and can elastically displace the elastic locking piece 353 to release the locked state. In this locking mechanism 350, the protruding direction of the release operation portion 355 is orthogonal to the insertion direction of the insertion path 351 and is the same direction as the displacement direction of the locking portion 354. An opening portion 356 is formed in the peripheral wall 352 on the other end side of the locking body 310, and the release operation portion 355 extends into the external space of the locking body 310 through the opening portion 356. The release operation portion 355 has a protrusion at the tip so that it is easy for the user to pinch it from the front in its protruding direction. Also in this modification example, similarly, since the release operation portion 355 is not provided in the same direction with respect to the band body 330, when the user operates the release operation portion 355 with a finger or an operating tool to release the lock, the lock release operation can be performed without being obstructed by the band body 330. Therefore, the tightening band 300 of this modification example makes the lock release operation easier.

[0090] (2) The tightening device and the locking mechanism of the present invention are not limited to the configurations of the above embodiments. The positional relationship of each component of the locking mechanism of the present invention is not limited to the above embodiments. For example, FIGS. 22(a) and (b) show tightening bands 400 and 500 provided with locking mechanisms 450 and 450 of a modification example of the present invention. The tightening bands 400 and 500 are modifications of the tightening band 200 of the second embodiment. Components with the same last two digits among the components indicated by three digits have the same or similar features and the description thereof is partially omitted unless otherwise explained.

[0091] In the locking mechanism 450, the elastic locking piece 453 is provided on the inner wall of the side (one end side) that forms the annular space 401 of the locking body 410, and the locking portion 454 is arranged to face the direction away from the annular space 401 (the other end side). And the release operation portion 455 protrudes from the elastic locking piece 453 to the outside of the insertion path 451 through the release portion 456 in a direction intersecting both the insertion direction of the insertion path 451 and the displacement direction of the locking portion 454. Along with this arrangement, a locked portion 433 is formed on the inner surface of the band body 430. In this form, the user can perform the unlocking operation by pressing the release operation portion 455 toward the annular space 401 to displace the elastic locking piece 453. On the other hand, in the locking mechanism 550, the elastic locking piece 553 extends along the insertion direction of the insertion path 551 from the top wall 511 of the locking body 510. And the release operation portion 555 protrudes from the elastic locking piece 553 to the outside of the insertion path 551 through the release portion 556 in a direction intersecting both the insertion direction of the insertion path 551 and the displacement direction of the locking portion 554. The elastic locking piece 553 may have a fixed end on the side of the outlet 551b of the insertion path 551. That is, within the technical scope of the present invention, the positional relationship of each component may be arbitrarily changed.

[0092] (3) The tightening device and the locking mechanism of the present invention are not limited to the configurations of the above embodiments. In the above embodiments, the tip of the elastic locking piece does not extend from the inlet or the outlet of the insertion path. However, the locking mechanism of the present invention may be configured such that, in addition to the configuration of the release operation portion, the tip portion of the elastic locking piece extends from the inlet or the outlet of the insertion path.

[0093] (4) The tightening device and the locking mechanism of the present invention are not limited to the configurations of the above embodiments. In the above embodiments, the protruding direction of the release operation portion is determined to be a direction orthogonal to both the insertion direction of the insertion path and the displacement direction of the locking portion (orthogonal to the insertion direction), but the present invention is not limited to this. That is, the intersection includes intersecting at an intersection angle other than a right angle, and the protruding direction of the release operation portion may be inclined from the direction orthogonal to both the insertion direction of the insertion path and the displacement direction of the locking portion.

[0094] (5) The wiring and pipe material holder (or tightening band) of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe material holder (or tightening band) of the above embodiment, the base (locking body), the band body, and the locking mechanism are integrally formed, but they may be a combination of separate bodies.

[0095] (6) The tightening device and the locking mechanism of the present invention are not limited to the configuration of the above embodiment. In the above embodiment, the locking portion is composed of one locking tooth or claw, but the locking portion may be a row of locking teeth composed of a plurality of locking teeth.

[0096] The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various aspects as long as it belongs to the technical scope of the present invention. That is, within the technical scope of the present invention, some configurations of the present embodiment may be omitted or modified, or other configurations may be added.
