摘要： A presser foot position retainer includes a presser foot and a restricting member. The presser foot is swingably attachable to a presser holder of a sewing machine. The presser foot includes a shaft extending in an axial direction, a restricted portion, and a pressing surface configured to press a workpiece. The restricting member includes a restricting portion capable of contacting the restricted portion. The restricting member is attachable to the presser holder. The restricting member is configured to move between a first position and a second position by a user operation. When the restricting member is located at the second position, the restricting portion is in contact with the restricted portion to limit a swingable range within which the presser foot attached to the presser holder is swingable about the shaft to less than that when the restricting member is located at the first position.

摘要： A presser foot device includes a wall portion, a pair of opposed portions, a pin, and an abutting portion. The wall portion extends in a first direction and a second direction intersecting the first direction. The pair of opposed portions extend in one direction of a third direction intersecting the first direction and the second direction from the wall portion, and face each other. The pin extends in the second direction between the pair of opposed portions, and engages with a groove provided in the presser foot holder. The abutting portion is provided with respect to the pin on one direction side of the first direction, and is provided on the one direction side of the third direction of an end surface in the one direction of the third direction, of the pair of opposed portions. The abutting portion abuts against the pressor foot holder in the second direction.

摘要： A screw tightening tool includes a case body, a tool member, and a switching portion. The case body includes a guide portion configured such that a head portion of a screw is inserted therein. The tool member includes an engaging portion including a bit portion configured to engage with the head portion. The switching portion supports the tool member. The switching portion is configured to switch a position of the tool member among a first positon, a second position, and a third position. The first position is a position in which the bit portion protrudes to an outside from the case body. The second position is a position in which the bit portion protrudes to the outside from the case body and that is different from the first position. The third position is a position in which the case body houses the bit portion.

摘要： In a lower thread winding device, a motor rotates a thread winding shaft on which a bobbin is mounted. A sensor lever includes a contact portion contactable with a lower thread wound on the bobbin, and a cam piece. A contact includes a pin configured to contact the cam piece and rotates between a first position at which the pin contacts a first outer peripheral portion of the cam piece, and a second position at which the pin contacts a second outer peripheral portion of the cam piece. A lever shifts a position of the pin located when the contact is at the first position. The controller drives the motor when the contact is at the first position and stops driving the motor upon receipt of a detection result, by the detector, indicating that the contact is at the second position.
