A hair removal tool is equipped with: a drive unit for driving a blade; a load detection unit for detecting the size of the load on the drive unit; and a control unit for changing the drive mode of the drive unit between a first drive mode for driving the drive unit at a first drive speed, a second drive mode for driving the drive unit at a second drive speed which is faster than the first drive speed, and a transition mode for driving the drive unit at a transition speed which is faster than the second drive speed. A first interval is set as the interval from when the drive mode is changed from the first drive mode to the transition mode until when the drive mode is changed from the transition mode to the second drive mode. A second interval is set as the interval from when the drive mode is changed from the transition mode to the second drive mode until when the drive mode is changed from the second drive mode to the first drive mode. The first interval is shorter than the second interval.

A support arm that is rockably supported on one end of a grip portion and projects from the one end is provided. Both ends of a blade head are supported by the support arm such that the blade head can rock around an axis extending along a reciprocating direction of an inner blade, and an axial direction of the rocking motion of the support arm with respect to the grip portion is set in a direction intersecting with the reciprocating direction of the inner blade. This configuration achieves an electric shaver capable of increasing the movable range of the blade head while preventing a main body from increasing in size.

Electric shaver

An electric shaver including: a gripper portion to be held by the user's hand; and a head portion configured to hold a shaving-blade unit and supported to be swingable in predetermined directions with respect to the gripper portion, wherein the head portion is provided with an edge-trimmer-blade unit.

A switch is coupled to a switch support and includes a push button, a lock assembly, a tab, and a hook. The lock assembly includes an operation ring, which is rotated about the button between an unlock position to permit actuation of the button and a lock state to prohibit actuation of the button, and a lock ring, which is rotated integrally with the operation ring. When the operation ring is located at the lock position, the hook and the tab are arranged at the same position in a circumferential direction, which creates interference between the hook and the tab and blocks actuation of the button. When the operation ring is located at the unlock position, the hook and the tab are separated from each other in the circumferential direction, which avoids interference between the hook and the tab and permits actuation of the button.

Switch

An electric shaver including: a gripper portion to be held by the user's hand; and a head portion configured to hold a shaving-blade unit and supported to be swingable in predetermined directions with respect to the gripper portion, wherein the head portion is provided with: an edge-trimmer-blade unit configured to be switched between a ready-for-use state and a stored state by an operation element; and a engaging portion for fixing the head portion, the engaging portion configured to be engaged with the operation element when the edge-trimmer-blade unit is switched to the ready.

The invention provides a hair removing apparatus having a body hair treatment head removing a body hair by shaving the body hair, depilating the body hair or cutting the body hair, and a main body grip held by a hand, and in which the body hair treatment head being rotatably coupled to the main body grip in such a manner that the body hair treatment head is freely oscillated with respect to the main body grip. In this structure, the hair removing apparatus is provided with a weight applying means for applying a force opposing to a force by which the body hair treatment head is oscillated by its own weight of the body hair treatment head around a center of rotation of the body hair treatment head.
