For this reason, the bottom surface portion 97 is formed with a protruding portion 102 that is substantially flush with the rear end portion of the dust collecting chamber R and that is the front side wall of the groove portion 101 at the front end portion. A restriction wall 103 serving as a rear side wall of the groove 101 is formed.

  When the dust collecting cup 3 shown in FIG. 1 is mounted around the fine dust filter 95, the filter frame 96 is in close contact with the outer peripheral edge of the rear surface of the mounting frame 76 and has a gap with the downstream side of the pleated filter 75. A seal member 104 is attached to close the door. In addition, a pair of reinforcing ribs 105 having a trapezoidal shape in a side view are provided on the upper portion of the filter frame portion 96 so as to protrude in front of the fitting recess 94.

  For this reason, in a state where the dust collecting cup 3 is attached to the dust collecting chamber R, the front end portion of the engaging portion 79 of the dust collecting cup 3 exceeds the filter frame portion 96 from the front side of the fitting concave portion 94. It protrudes above the protrusion 102.

  In addition, the main body lid 6 includes a covering portion 106 that covers the inner portion 91 of the upper case 86 in a closed state, and an opening 5 of the dust collection chamber R that is provided integrally with the covering portion 106 and that is closed.

  At the rear end portion of the covering portion 106, a pair of shaft support portions 111, 111 supported by the respective cover shaft support recesses 92 are provided so as to face each other toward the center side in the width direction. The covering portion 106 is provided with a round hole-shaped exposed hole portion 112 through which the clogging notification portion 93 is exposed when the main body lid 6 is closed. Further, at the position closer to the front side of the back surface of the covering portion 106, that is, the back surface, a movable body 113 as a detecting body that can be fitted into the fitting recess 94, and the lid body portion 107 that is positioned in front of the movable body 113 and covers the lid main body portion 107. Partition walls 114 that are continuous in the left-right direction.

  The movable body 113 determines whether the dust collection cup 3 is attached to the dust collection chamber R or whether the filter body 18 is attached to the dust collection cup 3 attached to the dust collection chamber R. Rotating shaft formed over the left and right at the upper end so that the main surface is directed in the front-rear direction, that is, the thickness direction is front-rear. 116 is pivotally supported on the covering portion 106 via a mounting member 117 so as to be rotatable.

  Further, the movable body 113 has a width dimension smaller than the distance between the side wall portions 98, 98 which is the width dimension of the fitting recess 94. Furthermore, an insertion hole 118 through which the attachment member 117 is inserted is formed below the rotation shaft 116 of the movable body 113. In addition, an inclined surface 119 is formed on the front surface of the movable body 113 from the middle portion in the vertical direction to the lower end so that the thickness of the movable body 113 is reduced.

  The movable body 113 has a groove portion of the fitting recess 94 when the dust collection cup 3 is not attached to the dust collection chamber R or when the filter body 18 is not attached to the dust collection cup 3. When the dust collecting cup 3 to which the filter body 18 is attached is attached to the dust collecting chamber R by being fitted to 101 and abutting against the regulating wall 103, it becomes a stopper of the main body lid 6. The main body lid 6 can be completely closed by abutting and being accommodated in the fitting recess 94. That is, the movable body 113 is a part of the body lid 6 that is a notification means, and the dust collection cup 3 is not attached to the dust collection chamber R, or the filter body 18 is attached to the dust collection cup 3. The detection means 120 for detecting a state where the operation is not performed is configured together with the locking portion 79 and the fitting recess 94.

  The mounting position of the movable body 113 to the main body lid 6, the length dimension, the angle of the inclined surface 119, and the like are appropriately set according to the position of the fitting recess 94, the depth of the groove 101, the front and rear width, and the like. Yes.

  The rotating shaft 116 is urged forward by a torsion spring (not shown) as urging means.

  The mounting member 117 includes a mounting bottom 121, a pair of mounting side portions 122 (only one shown) that rises from both sides of the mounting bottom 121, and a mounting front side that is continuous from the front end of the mounting bottom 121 to the mounting mounting side portion 122. A part 123 and a mounting rear side part 124 that rises from the rear end of the mounting bottom part 121 and continues between the mounting side parts 122 are formed in a frame shape with the upper side opened.

  A screw portion 128 having a screw hole 127 for screwing a mounting member 117 with a screw S to a boss 126 projecting downward from the back surface of the covering portion 106 is formed at a position closer to the front side of the mounting bottom portion 121. In addition, a stopper portion 129 for restricting the forward rotation of the movable body 113 is provided continuously from the rear portion of the screw portion 128.

  Each mounting side portion 122 is inserted into the insertion hole portion 118 to support the rotating shaft 116 from below, and the rotating shaft 116 is pivotally supported so as to be rotatable between the covering portion 106 of the main body lid 6. A shaft support recess 131 (only one is shown) is cut out from the upper end. The shaft support recess 131 has a lower end formed in an arc shape corresponding to the shape of the rotation shaft 116.

  The mounting rear side portion 124 is formed so that the distance from the center of the arc-shaped portion of the lower end portion of the pivot support recess 131 is smaller than the distance from the rotation shaft 116 of the movable body 113 to the insertion hole 118. The body 113 is configured not to interfere with the insertion hole 118 when the body 113 rotates backward.

  The partition wall 114 protrudes so that the lower end of the partition wall 114 is in contact with the upper surface of the filter mounting portion 25 of the dust collecting cup 3 in a state where the main body lid 6 is closed.

  The lid main body 107 is continuous from both sides of the covering portion 106 to the front, and is gently curved to both sides and to the front. The lid main body 107 is provided with a projection (not shown) on the back side of the outer peripheral edge, for example, and this projection is provided along the edge of the opening 5 of the dust collection chamber R of the upper case 86. A click feeling is generated when the main body lid 6 is completely closed, for example, by being fitted to a fitting portion that is not.

  Next, the operation of the first embodiment will be described.

  When using the vacuum cleaner, first, the dust collecting cup 3 is assembled. That is, in the dust collection cup 3, the separation body 16 and the filter body 18 are mounted in advance on the dust collection body 15.

  In the state where the separating body 16 is not attached, as shown in FIG. 7, the detecting body 55 is in the first locked position where the filter body locking portion 55c is in contact with the right edge portion shown in FIG. Thus, the laterally extending portion 55g of the separation portion lock portion 55b protrudes from the fitting notch portion 57 of the dust collecting portion main body 15 to the side of the fitting step portion 28, and the waste opening 23 cannot be closed by the opening / closing lid 17. ing. Further, when the filter body 18 is to be attached to the dust collector main body 15 from the state in which the filter body 18 is removed, the filter body lock portion 55c contacts the surrounding wall portion 82a of the surrounding portion 82 of the filter body 18. The filter body 18 cannot be attached to the filter mounting portion 25 in contact therewith.

  When the separator 16 is attached, when the separator 16 is inserted upward from the disposal opening 23, that is, from the lower side with the opening / closing lid 17 open, the rectifier 45 and the like are held by the holding frame 27 and fitted. The reinforcing rib 51c of the joint part 51 and the fitted vertical part 51b are fitted and held in the horizontal part 28a and the vertical part 28b of the fitting step part 28, respectively. Fixed to.

  At this time, the unlocking rib 51d of the separator 16 is inserted into the insertion hole portion 54f, the locking insertion hole 55d, and the protruding insertion hole portion 54g, and the rib inclined surface 51e abuts on the guide inclined surface 55j, so that the separator As the lock release rib 51d advances upward with the insertion of 16, the detection body 55 slides to the left shown in FIG. 8 against the elasticity of the spring 56 as shown in FIG. Since the laterally extending portion 55g of the separation portion lock portion 55b does not protrude beyond the fitted portion 51, the disposal opening 23 can be closed by the opening / closing lid 17.

  When the separating body 16 is removed from the dust collecting section main body 15 with the filter body 18 being locked and fixed to the filter mounting section 25 of the dust collecting section main body 15, as shown in FIG. Is slightly extended and the filter body lock portion 55c of the detection body 55 comes into contact with the surrounding wall portion 82a, so that the laterally extending portion 55g extends from the fitting cutout portion 57 to the side of the fitting step portion 28 of the dust collecting portion main body 15. The waste opening 23 cannot be closed by the opening / closing lid 17.

  Furthermore, when the dust collector main body 15 to which the separator 16 is attached is inserted into the dust collector main body 15 through the exhaust port 24 on the side opposite to the dust removing mechanism section of the filter body 18 and pushed in, the filter body lock section 55c is inserted into the encircling portion 82 and does not hinder the attachment of the filter body 18 to the filter mounting portion 25, and the locking projection 84 of the filter mounting portion 25 is inserted into the engaging hole 83 of the locking portion 79. The body 18 is locked and fixed to the filter mounting portion 25.

  Then, the waste opening 23 is closed by the opening / closing lid 17, and the dust collecting cup 3 having the filter body 18 attached to the filter mounting portion 25 is opened by rotating the body lid 6 of the cleaner body 1 rearward and upward. 5 is inserted and attached in the exposed dust collection chamber R, and the main body lid 6 is rotated forward and downward.

  At this time, as shown in FIG. 11, the inclined surface 119 of the movable body 113 comes into contact with the upper end portion of the locking portion 79 that protrudes into the fitting recess 94 beyond the filter frame portion 96 of the upper case 86. The body 113 rotates backward against the urging force of the torsion spring, so that the tip of the movable body 113 rotates backward without being fitted into the groove 101 and is stored in the fitting recess 94. Then, the main body lid 6 is completely closed.

  When the dust collecting cup 3 whose opening / closing lid 17 is not completely closed is attached to the dust collecting chamber R, the locking portion 79 protrudes upward from the opening 5 of the dust collecting chamber R, so that the main body lid 6 The dust collection chamber R cannot be closed at.

  Thereafter, the power cord 14 is connected to an outlet (not shown), the hose body 8, the extension pipe 12 and the floor brush 13 are sequentially connected to the main body suction port 7, and the hand grip portion 10 of the hand operation portion 9 is gripped. When the setting button 11 is operated, the electric blower 2 is driven to a predetermined operation mode by the control circuit.

  The operator runs the floor brush 13 back and forth on the floor surface and sucks dust on the floor surface together with air.

  This sucked air becomes suction air, and flows together with dust from the floor brush 13 to the extension pipe 12, the hose body 8 and the main body suction port 7, and is sucked into the dust collecting cup 3 from the suction opening 21.

  Further, as shown in FIG. 1, the sucked air sucked flows into the separation portion 44 through the cylindrical portion 22, and the flow velocity is caused by the rectifier 45 and the separation portion recess 43 in the separation portion 44. The coarse dust, which is relatively heavy in weight, travels straight along the separation part 44 along with this suction air and is collected from the communication opening 46 into the coarse dust container 47, and the fine dust, which is relatively light in weight, The suction air is collected by the mesh filter 62 when passing through the mesh filter 62.

  The suction air flowing into the coarse dust container 47 together with the coarse dust further collects fine dust when passing through the filters 65 and 67, and the suction air passing through the compression filter 67 is collected in the coarse dust container The coarse dust contained in 47 is pressed against the compression filter 67 to compress the volume of the coarse dust.

  The suction air that has passed through the filters 65 and 67 passes through the pleated filter 75 together with the suction air that has passed through the mesh filter 62 and is exhausted from the exhaust port 24 to the outside of the dust collection cup 3. Fine dust is further collected by the fine dust filter 95 at the rear and sucked into the electric blower 2.

  Thereafter, the suction air passes through the electric blower 2 to become exhaust air, and is exhausted to the outside of the cleaner body 1 through an exhaust hole (not shown).

  When the coarse dust container 47 is full or various filters such as the pleat filter 75 are clogged during cleaning, the clogging notification unit 93 operates to notify the operator.

  At this time, the operator stops the electric blower 2, rotates the main body lid 6 to open the opening 5, removes the dust collecting cup 3 from the dust collecting chamber R, and operates the dust dropping mechanism unit to the pleat filter 75. After dropping the fine dust collected in the fine dust container 80, press the open / close button 74 of the open / close mechanism 68 on the trash can, etc., and release the engagement / disengagement projection 69 of the open / close lid 17 The open / close lid 17 rotates by its own weight around the pivoted support, the coarse dust container 47 and the fine dust container 80 are opened at the same time, and the stored coarse dust and fine dust are discharged from the disposal opening 23 into the trash can. It is dropped and discarded. When cleaning the pleated filter 75 of the filter body 18, the filter body 18 may be detached from the dust collecting body 15 and the dust dropping mechanism section may be operated to perform maintenance separately.

  Further, when cleaning the dust collecting cup 3, the separator 16 is pulled out from the disposal opening 23 in an inclined manner toward the front side of the dust collecting body 15 from the disposal opening 23.

  The removed separating body 16 eliminates clogging of the filters 62, 65, 67 by backwashing the filters 62, 65, 67 with water, for example.

  After the separated separator 16 is sufficiently dried, it is reattached to the dust collector main body 15 by the reverse operation of the removal, and the open / close lid 17 is closed.

  When the filter body 18 is removed from the dust collection body 15, the dust collection cup 3 is attached to the dust collection chamber R again with the filter body 18 also mounted on the filter mounting section 25.

  As described above, according to the first embodiment, when the separator 16 having the separator 44 is not attached to the dust collector main body 15, the open / close lid 17 does not close the waste opening 23. Since the opening / closing lid 17 is not closed, the operator can be informed that the separating body 16 having the separating portion 44 is not attached to the dust collecting cup 3, and the separating body 16 is not attached to the dust collecting portion main body 15. It is possible to prevent the dust collecting cup 3 from being misused.

  Furthermore, in a state where the separating body 16 having the separating portion 44 is not attached to the dust collecting portion main body 15, the filter body 18 cannot be attached to the exhaust port 24. The operator can be informed that the separator 16 having the dust collector 3 is not attached to the dust collector cup 3, and that the dust collector cup 3 is misused without the separator 16 being attached to the dust collector main body 15. Can be prevented.

  When the filter body 18 is not attached to the dust collecting body 15, the main body lid 6 does not close the dust collecting chamber R, and the main body lid 6 does not close so that the separator 16 is attached to the dust collection cup 3. The detection means 120 can indirectly detect that this is not done and notify the operator, and the dust collecting cup 3 without the separator 16 attached is mistakenly attached to the dust collecting chamber R and a vacuum cleaner is used. Can also be prevented.

  Moreover, since the detection means 120 does not close the dust collection chamber R with the main body lid 6 even when the dust collection cup 3 is not attached to the dust collection chamber R, the dust collection cup 3 is collected by the main body lid 6 not closing. The operator can be informed that the dust chamber R is not attached to the dust chamber R, and the vacuum cleaner can be prevented from being used in a state where the dust collection cup 3 is not attached to the dust chamber R.

  Further, in a state where the dust collecting cup 3 whose opening / closing lid 17 is not closed is attached to the dust collecting chamber R, the upper end portion of the dust collecting cup 3 protrudes upward from the dust collecting chamber R by the opening / closing lid 17 and the main body lid 6 is collected. Since the dust chamber R is not closed, the operator can be informed that the separator 16 is not attached to the dust collection cup 3 by not closing the main body lid 6.

  That is, each of the opening / closing lid 17, the filter body 18 and the main body lid 6 serves as a multiple protection means for notifying the operator that the separation body 16 has been forgotten to be attached. Usability of the vacuum cleaner is improved.

  In particular, in a vacuum cleaner in which the dust collection cup 3, the separator 16 and the filter body 18 are removable, and the dust collection cup 3 can be easily maintained, forgetting to attach the dust collection cup 3 to the dust collection chamber R or separating it. Since there is a possibility that the dust collecting cup 3 may be attached to the dust collecting chamber R without forgetting to attach the separating body 16 or the filter body 18 having the portion 44, it is possible to collect the dust collecting cup by configuring it as in the first embodiment. The electric blower 2 can be cleaned without attaching the dust cup 3 to the dust collecting chamber R or by attaching the dust collecting cup 3 without the separator 16 or filter 18 attached to the dust collecting chamber R for cleaning. It is possible to reliably prevent the electric blower 2 from being damaged by sucking dust.

  In addition, a configuration in which the opening / closing lid 17 is not closed with respect to the dust collecting unit main body 15 to which the separation body 16 is not attached, or a configuration in which the filter body 18 is not attached is provided with the detection body 55 including the lock portions 55b and 55c, the spring By forming with 56 and the surrounding part 82, these structures can be made inexpensive.

  Further, the upper wall portion 82c of the surrounding portion 82 provided on the dust dropping inclined surface 81 for dropping the fine dust collected by the pleat filter 75 to the fine dust containing portion 80 is moved to the front side in the same manner as the dust dropping inclined surface 81. By tilting downward, the fine dust dropped from the pleated filter 75 to the fine dust accommodating portion 80 is less likely to adhere to the surrounding wall portion 82c.

  Further, the main body lid 6 is separated into a state where the dust collection cup 3 is not attached to the dust collection chamber R by not closing the opening 5 of the dust collection chamber R, and a dust collection cup 3 attached to the dust collection chamber R. Compared with the case where a buzzer or the like is separately provided as a notification means by using as a notification means to notify when the detection means 120 detects either 16 or the state in which the filter body 18 is not mounted. The notification means can be easily configured and the visibility of the notification can be improved.

  Furthermore, the attachment state of the filter body 18 to the dust collection cup 3 is directly connected to the dust collection cup 3 of the separation body 16 via a locking portion 79 that locks the filter body 18 to the dust collection body 15. Since the movable body 113 can indirectly detect the mounting state of the filter body 18, the locking portion 79 of the filter body 18 can be effectively used, the state where the dust collection cup 3 is not attached, and the separation body 16 or the filter body 18. Can be reliably detected by the movable body 113 provided on the main body lid 6.

  Specifically, the movable body 113 that is rotatably provided in the state of being biased forward on the back side of the main body lid 6 includes the case where the dust collection cup 3 is not attached to the dust collection chamber R, and the dust collection chamber R. A stopper that prevents the body lid 6 from being completely closed by fitting in the groove 101 of the fitting recess 94 provided in the upper case 86 when the filter body 18 is not attached to the dust collecting cup 3 attached to Thus, only when the locking portion 79 of the filter body 18 is located in the dust collecting chamber R, the locking portion 79 contacts the movable body 113 and the movable body 113 is accommodated in the fitting recess 94. By configuring the main body lid 6 so as to be completely closed, the notification unit and the detection unit 120 can be configured simply and the productivity can be improved.

  That is, since the movable body 113 of the main body lid 6 serving as the notification means forms the detection means 120 with the groove portion 101 of the fitting recess 94 and the locking portion 79 of the filter body 18, the main body lid 6 is connected to the notification means and the detection means 120. The configuration can be simplified as compared with the case where the notification unit and the detection unit are provided separately.

  In particular, the filter body 18 attaches and detaches the pleated filter 75, which is a fine dust filter, to the dust collecting cup 3, so that the dust collecting cup 3 is collected without the pleat filter 75 collecting fine dust. It is possible to reliably prevent fine dust from being sucked into the electric blower 2 by being misused by being attached to the chamber R.

  Moreover, by providing the movable body 113 on the back surface of the main body lid 6, the movable body 113 does not impair the appearance of the electric vacuum cleaner, and when the main body lid 6 is closed, it is difficult for the operator to touch the movable body 113. Therefore, the movable body is opened when the main body lid 6 is opened and closed with the dust collection cup 3 not attached to the dust collection chamber R and the dust collection cup 3 not attached with the separator 16 or the filter body 18 attached to the dust collection chamber R. It is possible to reliably prevent the 113 from being operated by mistake, and it is possible to perform reliable detection and notification.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In this second embodiment, instead of providing the detecting means 120 of the first embodiment, a dust collecting cup 3 not having a separator 16 having a separating portion 44 attached thereto is attached to the dust collecting chamber R. It is configured so that it is not possible.

  That is, in the second embodiment, the width dimension of the dust collection chamber R is formed to be substantially equal to the width dimension of the dust collection cup 3.

  As a result, the dust collection cup 3 to which the separator 16 is not attached cannot be attached to the dust collection chamber R because the laterally extending portion 55g of the detection body 55 protruding sideways contacts the side portion of the dust collection chamber R. Thus, the operator is informed of the forgetting to attach the separating body 16 having the separating portion 44 to the dust collecting body 15 and the forgetting to attach the separating body 16 having the separating portion 44 as in the first embodiment. This can be prevented, and the configuration can be simplified as compared with the case where the detection means 120 is provided.

  Next, a third embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the third embodiment, instead of providing the detection means 120 of the first embodiment, the dust collection cup 3 not attached with the filter body 18 cannot be attached to the dust collection chamber R. It is a thing.

  That is, as shown in FIGS. 16 and 17, a slit portion 135 is cut along the front-rear direction on one side portion of the holding frame portion 27 of the dust collecting portion main body 15, and on the side portion of the slit portion 135. The filter mounting detection means 136 is attached.

  The filter attachment detection means 136 includes a case portion 141 fixed to the filter attachment portion 25, a detection piece 142 accommodated between the case portion 141 and the filter attachment portion 25, and the detection piece 142 in the backward direction. A biasing spring 143 for biasing is provided.

  The case portion 141 has an upper surface portion 145, a lower surface portion 146, a front surface portion 147, a side surface portion 148, and a rear surface portion 149, and has a lid shape that divides a space portion that houses the detection piece 142 with the filter mounting portion 25. The rear surface portion 149 is formed with an opening 151 projecting rearward. The opening 151 is provided at a position corresponding to the slit portion 135 and communicating with the slit portion 135.

  The detection piece 142 includes a protruding tip 153 that protrudes rearward from the opening 151, and a retaining portion 154 that is provided at the front of the protruding tip 153.

  The protruding tip 153 protrudes rearward from the opening 151 on the side of the slit portion 135.

  The retaining portion 154 is formed to be large in the vertical direction with respect to the protruding tip portion 153, and is accommodated between the case portion 141 and the filter mounting portion 25 so as to be slidable in the front-rear direction. Further, the retaining portion 154 is in contact with the front side of the rear surface portion 149, thereby restricting the maximum sliding position of the detection piece 142 toward the rear side.

  The biasing spring 143 is disposed between the front surface portion 147 of the case portion 141 and the retaining portion 154 of the detection piece 142, and its elastic force holds the filter body 18 against the dust collecting portion main body 15. It is set smaller than the force.

  On the other hand, on one side portion of the attachment frame 76 of the filter body 18, a rib 155 that can be fitted into the slit portion 135 is provided in a front-rear direction at a position corresponding to the slit portion 135. The rib 155 is positioned closer to the rear side than the filter packing 77 of the filter body 18.

  When the filter body 18 is attached to the dust collector main body 15, as shown in FIG. 17 (b), the rib 155 fits into the slit 135 (FIG. 16) and contacts the protruding tip 153 of the detection piece 142. In contact with the elastic force of the biasing spring 143, the projecting tip 153 of the detection piece 142 is pushed into the front side of the case part 141 while the biasing spring 143 is pressed and shrunk, so that the protruding tip 153 of the detection piece 142 is a dust collecting part. The dust collection cup 3 can be attached to the dust collection chamber R without protruding backward from the main body 15.

  On the other hand, in a state where the filter body 18 is not attached to the dust collector main body 15, as shown in FIG. 17 (a), the projecting tip 153 of the detection piece 142 projects rearward from the exhaust port 24, so that FIG. As shown, when the dust collecting cup 3 is attached to the dust collecting chamber R, the protruding tip 153 comes into contact with the upper edge of the dust collecting chamber R so that the dust collecting cup 3 can be attached to the cleaner body 1. Accordingly, the operator is notified of forgetting to attach the filter body 18 to the dust collector main body 15, and the forgetting to attach the filter body 18 can be prevented in the same manner as in the above embodiments.

  In the third embodiment, the filter attachment detection means 136 including the protruding tip 153, the slit 135, and the like can be provided on the cleaner body 1 side.

  Further, in each of the above embodiments, when the separator 16 is not attached to the dust collector main body 15, both the configuration in which the opening / closing lid 17 is not closed and the configuration in which the filter body 18 is not attached are provided. However, it is also possible to adopt a configuration having only one of them.

  Further, the various configurations for detecting the attachment of the separator 16 or the filter body 18 to the dust collector main body 15 are not limited to the above.

  For example, in each of the above embodiments, the separation portion lock portion 55b and the filter body lock portion 55c are integrally provided in one detection body 55, but the separation portion lock portion 55b and the filter body lock portion 55c Are separately provided, and when the separator 16 having the separator 44 is not attached to the dust collector main body 15, the lock portions 55b and 55c cause the closure of the waste opening 23 by the open / close lid 17 and the filter of the filter body 18. The attachment to the mounting part 25 can be locked separately, and when the separator 16 having the separation part 44 is attached to the dust collector main body 15, the lock parts 55b and 55c are interlocked with each other to release the lock. Also with respect to the configuration and the like, it is possible to achieve the same operational effects as the above-described embodiments.
