Abstract: Several means 71, 72, 73, 74, and 75 are provided for restricting a relative displacement in a separating direction of half-split housings 50L, 50R. At one or more of several screw-connection parts 60 of the left and right half-split housings 50L, 50R, a press-fitting protrusion 71a is provided in an insertion hole 62a of a boss-receiving part 62 into which a screw-boss part 61 is inserted. By press-fitting the screw-boss part 61 to the boss-receiving part 62, a separation resistance may be introduced between the left and right half-split housings 50L, 50R.

Abstract: A grinder includes a brake mechanism, a switch lever, and a slide bar. In the grinder, an interlocking mechanism configured to interlock the brake mechanism with the switch lever includes a link member that is interposed between the switch lever and the slide bar, that moves the slide bar to the forward position at the push-in position of the switch lever, and that moves the slide bar to the retraction position at the initial position of the switch lever.

CPC classification number: B24B55/052 , B24B23/028
Abstract: A grinder includes a motor, a housing, a spindle and a cover. The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The cover at least partially covers a tool accessory mounted on the spindle. The cover includes a first cover part and a second cover part. The first cover part is fixed to the housing and at least partially covers the tool accessory from above. The second cover part is held such that it is capable of moving relative to the first cover part. The grinder is configured such that the area of the tool accessory covered by the cover changes in accordance with the relative movement.
Abstract translation: 研磨机包括马达，外壳，主轴和盖子。 主轴从壳体向下突出，由电机驱动，从而旋转。 盖至少部分地覆盖安装在主轴上的工具附件。 盖包括第一盖部分和第二盖部分。 第一盖部分固定到壳体并且至少部分地从上方覆盖工具附件。 第二盖部被保持成能够相对于第一盖部移动。 研磨机被构造成使得由盖子覆盖的工具附件的区域根据相对运动而变化。

Abstract: A vacuum cleaner includes: an inlet pipe; and a lock mechanism that fixes an extension pipe, which is connected to the inlet pipe. The lock mechanism includes a pipe-lock lever, which has a pipe-hook part that is hooked into a pipe-recess part provided on the extension pipe. The pipe-lock lever also has a main-body part, which is disposed on an upper portion of the inlet pipe and on which the pipe-hook part is disposed, and one or more projection parts, which project(s) laterally from a side portion or side portions of the main-body part.

Abstract: A cleaner reduces noise. The cleaner includes a motor, a fan including a number Z of blades and rotatable at a rotational speed N, indicating revolutions per minute, about a rotation axis by the motor, a cover having an inlet located frontward from the fan, and a number V of ribs located in the inlet. The ribs extend in a radial direction from the rotation axis and are arranged in a circumferential direction about the rotation axis. The fan is rotatable to produce noise having a frequency fNZ of 20,000 Hz or higher, and fNZ=(m−k×V)×N/60 and m=n×Z+k×V, where n is an order, m is an integer, and k is an integer.

Abstract: A cleaner reduces noise. The cleaner includes a motor assembly including a motor and a fan rotatable about a rotation axis with a rotational force generated by the motor, a cover surrounding the motor assembly, a guide that guides air from the fan at least partially to an outer surface of the cover, and a rib assembly that guides the air guided by the guide at least partially in a circumferential direction about the rotation axis along the outer surface of the cover.
