Abstract: A treatment tool includes: an insertion tube; a distal end part that is provided at a distal end of the insertion tube; a shaft that is provided in the distal end part and that includes an outer circumferential surface; and a pair of transmitters each of which is inserted into the insertion tube and is fixed to the distal end part, the pair of transmitters being configured to transmit a drive force that causes the distal end part to flex with respect to the insertion tube, each transmitter being arranged along the outer circumferential surface with the shaft being sandwiched between the pair of transmitters and, on a distal end side with respect to the shaft, the pair of transmitters extending in a state of being separate from each other in a distance smaller than a diameter of the outer circumferential surface of the shaft.

Abstract: A medical instrument includes a housing, a movable handle, and a spring. The movable handle is configured to move between a first position as an opened position and a second position as a closed position with respect to the housing. The spring is provided between the housing and the movable handle. The spring is configured to apply a biasing force to the housing or the movable handle. The spring is provided to alleviate an increase in the biasing force generated in the spring in response to the movable handle moving from the first position to the second position.

Abstract: A treatment tool includes: a sheath; a treatment portion that is capable of treating a living tissue and is provided at a distal end of the sheath; a first driver and a second driver that are inserted in the sheath and are capable of driving the treatment portion; and a holder that is inserted in the sheath, and holds the first driver and the second driver. The holder includes a groove in which the first and second driver are inserted, and an intervening portion provided in the groove and arranged between the first driver and the second driver in a cross section perpendicular to a longitudinal direction of the groove that extends from a distal end to a proximal end of the holder.

Abstract: A radar cover (10) includes a transparent member (11), a base member (13) that is disposed on a back surface of the transparent member (11) and supports the transparent member (11), and an inner emblem (12) that is disposed between the transparent member (11) and the base member (13), in which the inner emblem (12) includes an island portion (12a) of which a periphery is surrounded by a part of the base member (13) when viewed from a laminating direction, a peripheral portion (12b) that is disposed apart from the island portion (12a) when viewed from the laminating direction, and a connecting portion (12c) that is embedded in the base member (13) and connects the island portion (12a) and the peripheral portion (12b) when viewed from the laminating direction.
