Reciprocating saw
In a reciprocating saw, a slider that is reciprocated by a motor protrudes forward beyond a housing accommodating the motor. A blade that cuts a workpiece can be fixed to a joining portion provided at a tip end of the slider. A protector made of an elastic material is attached to the joining portion. The protector is provided with a contact portion capable of contacting the blade fixed to the joining portion.
1. A reciprocating saw, comprising:
a housing;
a motor accommodated in the housing;
a slider configured to be driven by the motor so that the slider reciprocates relative to the housing in a longitudinal direction, the slider having a forward tip end protruding forward beyond the housing, the slider having a joining portion at the forward tip end;
a blade fixedly retrained by the joining portion such that the blade reciprocates with the slider to cut a workpiece;
a protector made of an elastic material and extending about a periphery of the joining portion, the protector being rotatable relative to the blade; and
a contact portion provided on the protector, the contact portion extending beyond the forward tip end of the slider in the longitudinal direction and being rotatable with the protector between (i) a non-contact position relative to the blade and (ii) a contact position configured to contact a surface of the blade fixedly retained by the joining portion.
2. The reciprocating saw according to claim 1 , wherein
the contact portion is provided on the protector so that the contact portion can contact both sides of the blade.
3. The reciprocating saw according to claim 1 , wherein
the contact portion contacts the blade when the blade is fixed to the joining portion, and the contact portion does not contact the blade when the blade is not fixed to the joining portion.
4. The reciprocating saw according to claim 2 , wherein
the contact portion is formed by (i) a first protruding portion extending from a lower right region to an upper right region of a front end face of the protector so as to protrude from the front end face, having a generally fan shape spreading from a center side toward an outer peripheral side of the front end face as viewed from front, and capable of contacting a right side of the blade, and (ii) a second protruding portion extending from an upper left region to a lower left region of the front end face so as to protrude from the front end face, having a generally fan shape spreading from the center side toward the outer peripheral side of the front end face as viewed from the front, and capable of contacting a side of the blade.
5. The reciprocating saw according to claim 4 , wherein
a vertex portion of the first protruding portion is capable of contacting an upper part of the right side of the blade, and a vertex portion of the second protruding portion is capable of contacting a lower part of the left side of the blade.
6. The reciprocating saw according to claim 4 , wherein
the first protruding portion and the second protruding portion are made of rubber.
