Abstract: An air compressor improves the dustproof performance of an intake path to a crankcase. The air compressor includes a compression assembly that reciprocates a piston in a cylinder to produce compressed air, a crankcase accommodating the compression assembly and having an inner inlet to allow outside air to be drawn, a filter located in the crankcase and covering the inner inlet from outside, a filter cover having an outer inlet and covering the filter from outside, and a dust cover covering the filter cover from outside, covering the outer inlet, and including an outer circumferential portion. The outer circumference portion and the filter cover have a space to draw outside air between the outer circumference portion and the filter cover.

Abstract: An air compressor comprises a compressor that compresses introduced air and a tank that stores the compressed air generated by the compressor. The air compressor also comprises a discharge pipe from which the compressed air and a condensate in the tank are discharged to an outside of the tank. The air compressor also comprises a drain cock that is disposed in a passage of the discharge pipe and serves to open and close the discharge pipe. The air compressor also comprises a discharge pipe end portion that includes a discharge port facing upward at a tip end of the discharge pipe. The air compressor also comprises a tubular cover including a top portion that covers the discharge pipe end portion from above.

Abstract: A power tool is provided with a prime mover which causes the tool to rotate and a housing which houses the prime mover. In a back-end face that is positioned on an opposite side on the housing from a tool side, a back-end groove, into which a user can position his/her web between his/her thumb and forefinger, is formed. A pair of side-face grooves, into which the user can place the thumb and forefinger, are formed in both side faces of the housing. A depth changing portion is formed in at least one of the side-face grooves, such that the depth is reduced toward the back-end face of the housing. According to this structure, even when the housing is gripped directly from the back-end face, the user can easily draw up or raise the power tool.

Abstract translation: 电动工具设置有使得工具旋转的原动机和容纳原动机的壳体。 在从工具侧定位在壳体的相对侧的后端面中，形成有用户可以将他/她的网络放置在他/她的拇指和食指之间的后端凹槽。 在壳体的两个侧面形成有一对侧面凹槽，用户可以将拇指和食指放置在该侧面凹槽中。 在至少一个侧面凹槽中形成深度改变部分，使得深度朝向壳体的后端面减小。 根据该结构，即使在从后端面直接夹持住壳体的情况下，使用者也能容易地起动或升起电动工具。
