[0044] The battery mounting portion 5 is arranged at the lower part of the controller accommodating portion 22. The battery pack 13 is mounted on the battery mounting portion 5. The battery pack 13 functions as a DC power source for the reciprocating saw 1A. The battery pack 13 is detachable relative to the battery mounting portion 5. The battery pack 13 is mounted on the battery mounting portion 5 by inserting the battery mounting portion 5 from the left side of the battery mounting portion 5 to the right. The battery pack 13 is removed from the battery mounting portion 5 by pulling it out from the battery mounting portion 5 to the left. The battery pack 13 includes a secondary battery. In the present embodiment, the battery pack 13 includes a rechargeable lithium-ion battery. By being mounted on the battery mounting portion 5, the battery pack 13 can supply power to the reciprocating saw 1A. The motor 8 is driven by the power supplied from the battery pack 13.

[0045] The controller 7 controls at least the motor 8. The controller 7 includes a circuit board and a plurality of electronic components mounted on the circuit board. Examples of the electronic components include a microcomputer and a switch element. The controller 7 is housed in the rear case 2.

[0046] The motor 8 is a power source of the reciprocating saw 1A. The motor 8 is an electric motor. The motor 8 is an inner rotor type brushless motor. The motor 8 has a stator 15 and a rotor 16. The stator 15 is arranged around the rotor 16. The rotor 16 rotates relative to the stator 15. The rotor 16 rotates around the rotation axis AX. The rotation axis AX extends in the front-rear direction.

[0047] The stator 15 includes a cylindrical stator core 15A, a rear insulator 15B fixed to the rear of the stator core 15A, a front insulator 15C fixed to the front of the stator core 15A, and a plurality of coils 15D wound around the teeth of the stator core 15A via the rear insulator 15B and the front insulator 15C.

[0048] The rotor 16 has a rotor core 16A, a permanent magnet 16B, and a rotor shaft 16C. A sensor substrate 17 is mounted on the back insulator 15B, and the sensor substrate 17 detects the rotation of the rotor 16 by detecting the position of the permanent magnet 16B.

[0051] The rear end portion of the rotor shaft 16C is rotatably supported by a rotor bearing 20 . The rotor bearing 20 is held by the motor housing 18 .

[0052] The fan 9 is fixed to the front of the rotor shaft 16C. When the rotor shaft 16C rotates, the fan 9 rotates. By the rotation of the fan 9, an air flow is generated around the motor 8. The motor 8 is cooled by the air flow generated by the rotation of the fan 9.

[0053] A pinion gear 24 is provided at the front end of the rotor shaft 16C. The pinion gear 24 is arranged inside the gear case 19. The rotor shaft 16C is coupled to the reciprocating motion conversion mechanism 10 via the pinion gear 24.

[0054] The reciprocating motion conversion mechanism 10 converts the rotational motion of the rotor 16 into a reciprocating motion in the front-rear direction. The reciprocating motion conversion mechanism 10 is arranged at a position closer to the front side than the motor 8. The reciprocating motion conversion mechanism 10 reciprocates the blade 31 held by the slider 11 in the front-rear direction according to the rotational force of the motor 8. The slider 11 holds the blade 31 through the blade holder 30.

[0055] The reciprocating motion conversion mechanism 10 includes: a bevel gear 25 that is coupled to a pinion gear 24; a support shaft 26 that fixes the bevel gear 25; and an eccentric pin 27 that is provided at an eccentric position of the bevel gear 25. The support shaft 26 is rotatably supported by a bearing 28 and a bearing 29. A slider 11A is provided on the slider 11. At least a portion of the eccentric pin 27 is arranged inside the slider 11A. The bevel gear 25 rotates around a rotation axis BX that is orthogonal to the rotation axis AX. As the bevel gear 25 rotates and the eccentric pin 27 revolves around the rotation axis BX, the eccentric pin 27 moves in the left-right direction inside the slider 11A. As the eccentric pin 27 revolves around the rotation axis BX and moves in the left-right direction inside the slider 11A, the slider 11 reciprocates in the front-rear direction.

[0056] The slider 11 reciprocates in the front-to-back direction by the rotational force of the motor 8 transmitted via the reciprocating motion conversion mechanism 10. The slider 11 is guided in the front-to-back direction by the sliding guide 90 and the sliding guide 91. The slider 11 has a holder portion 11B for holding a blade 31 as a kind of top tool. The holder portion 11B is provided at the front end portion of the slider 11. The slider 11 functions as a top tool holding portion for mounting the top tool. The guide bearing 12 is provided at the front side of the slider 11.

[0057] The vise 40 is mounted on the vise mounting portion 6. The vise 40 is fixed to the cutting object. The vise 40 includes: a fixing member 41 that contacts the cutting object; a winding member 42 that is connected to the fixing member 41 and is wound around the cutting object; a fastener 43 that is operated to fasten the winding member 42; and a mounting member 44 that is mounted on the vise mounting portion 6.

[0058] The vise mounting portion 6 is arranged at a position on the front side of the motor 8. The vise mounting portion 6 is arranged at a position on the front side of the reciprocating motion conversion mechanism 10. The vise mounting portion 6 includes a hole provided at the front end portion of the front housing 4. The mounting member 44 includes a rod-shaped member inserted into the hole of the vise mounting portion 6. In the present embodiment, the winding member 42 is a chain. In the present embodiment, the vise 40 is a so-called chain vise.

[0059] The vise 40 is attachable to and detachable from the vise mounting portion 6. The vise 40 is attached to the vise mounting portion 6 by inserting the mounting member 44 into the vise mounting portion 6 from the left side to the right side. The vise 40 is removed from the vise mounting portion 6 by pulling the mounting member 44 out from the vise mounting portion 6 to the left side.

[0060] For example, when a pipe is cut as a cutting object, the operator brings the fixing member 41 into contact with a part of the pipe and winds the winding member 42 around the pipe. After the winding member 42 is wound around the pipe, the operator operates the fastener 43 to fasten the winding member 42 to the pipe. Accordingly, the vise 40 is fixed to the pipe. After the vise 40 is fixed to the pipe, the operator operates the trigger lever 14. After the trigger lever 14 is operated, the motor 8 is driven by the power supplied by the battery pack 13. When the rotor 16 rotates around the rotation axis AX, the pinion 24 provided at the front end of the rotor shaft 16C rotates. When the pinion 24 rotates, the bevel gear 25 coupled to the pinion 24 rotates. When the bevel gear 25 rotates, the eccentric pin 27 performs eccentric motion relative to the rotation axis BX of the bevel gear 25, and the slider 11 reciprocates in the front-rear direction. When the slider 11 reciprocates in the front-rear direction, the blade 31 mounted on the slider 11 reciprocates in the front-rear direction. While the blade 31 is reciprocating in the front-rear direction, the operator holds the handle 21 and rotates the reciprocating saw 1A around the mounting member 44. The operator holds the handle 21 and rotates the reciprocating saw 1A around the mounting member 44 so that the handle 21 moves upward and the blade 31 moves downward. As a result, the reciprocating blade 31 is pressed into the pipe, and the pipe is cut.

[0061] In this embodiment, the motor 8 and the battery mounting portion 5 are respectively arranged in front of the grip portion 21. The battery mounting portion 5 is arranged in the rear of the motor 8. The battery mounting portion 5 is arranged below the motor 8.

[0062] The controller 7 is arranged at the rear side of the motor 8. The motor 8, the battery mounting portion 5 and the controller 7 are arranged at the front side of the grip portion 21. In the present embodiment, the controller 7 is plate-shaped. The controller 7 is arranged so that the surface of the controller 7 is orthogonal to the rotation axis AX.

[0063] As described above, in this embodiment, the reciprocating saw 1A has a motor 8, a reciprocating motion conversion mechanism 10, a battery mounting portion 5 and a vise mounting portion 6, wherein the reciprocating motion conversion mechanism 10 is arranged at a position closer to the front side than the motor 8, and causes the blade 31 to reciprocate according to the rotational force of the motor 8; the battery mounting portion 5 is used to install the battery pack 13; the vise mounting portion 6 is arranged at a position closer to the front side than the motor 8, and is used to install the vise 40.

[0064] In the above-mentioned structure, by using the battery pack 13, which is a DC power source, as the power source of the reciprocating saw 1A, it is not necessary to connect an electric wire to the reciprocating saw 1A. Therefore, it is possible to suppress the deterioration of the operability of the reciprocating saw 1A equipped with the vise 40. In addition, since the power source of the reciprocating saw 1A is the battery pack 13, it is not necessary to secure an AC power source at the work site. Therefore, the operator can perform the work using the reciprocating saw 1A without being restricted by the work environment.

[0065] In the present embodiment, the reciprocating saw 1A includes a handle portion 21 . The motor 8 and the battery mounting portion 5 are respectively arranged on the front side of the handle portion 21 .

[0066] In the above structure, since the battery pack 13 as a heavy object is arranged at a position forward of the handle 21, the load applied to the operator can be reduced during the cutting operation using the vise 40. As described above, for example, when cutting a pipe, the operator rotates the reciprocating saw 1A around the mounting member 44 while holding the handle 21, so that the handle 21 moves upward and the blade 31 moves downward. Since the battery pack 13 as a heavy object is arranged at a position forward of the handle 21, the load applied to the operator can be reduced during the cutting operation using the vise 40.

[0067] In the present embodiment, the battery mounting portion 5 is arranged at a rearward side relative to the motor 8 .

[0068] In the above-described configuration, the weight balance of the reciprocating saw 1A can be optimized, and the load applied to the operator during the cutting operation using the vise 40 can be reduced.

[0069] In the present embodiment, the battery mounting portion 5 is arranged below the motor 8 .

[0070] In the above-described configuration, the weight balance of the reciprocating saw 1A can be optimized, and the load applied to the operator during the cutting operation using the vise 40 can be reduced.

[0071] In this embodiment, the vise 40 is installed on the vise mounting portion 6 by being inserted from one side to the other side of the vise mounting portion 6 in the left-right direction, and the battery pack 13 is installed on the battery mounting portion 5 by being inserted from one side to the other side of the battery mounting portion 5 in the left-right direction.

[0072] In the present embodiment, the reciprocating saw 1A includes a controller 7 that controls the motor 8. The controller 7 is disposed at a rear side relative to the motor 8.

[0073] In the present embodiment, the motor 8 , the battery mounting portion 5 , and the controller are respectively arranged on the front side of the grip portion 21 .

[0074] In the above configuration, since the battery pack 13 , the motor 8 , and the controller, which are heavy objects, are disposed forward of the grip portion 21 , the load on the operator during the cutting operation using the vise 40 can be reduced.
