The sliding operation portion and the block operation portion correspond to each other, an operation end portion is formed in one of them, and a guide cam surface corresponding to the operation end portion is formed in the other,
When the control shaft is rotated, due to the contact between the operating end portion and the guide cam surface and guidance of the guide cam surface, the interlock mechanism is
The first brake pad and the second slide in the first sliding member, the sliding base of the second sliding member being in a position approaching the block base of the control block An inoperative state in which the second braking pad on the member is in the inoperative position;
The sliding base of the second sliding member moves away from the block base of the control block, and the anchor is moved to the first sliding member by pushing the second sliding member toward the first sliding member. It is possible to switch between an operating state in which the first braking pad and the second braking pad are moved to the operating position by abutting against the first sliding member from the end portion side. Configured,
Brake caliper characterized by The interlocking mechanism is
A drive lever attached to the second end of the control shaft so as to be rotatable about the second axis together with the control shaft and extending so as to be substantially perpendicular to the second axis; The brake caliper according to claim 1. The housing is
A first frame formed with a first shaft hole that is inserted through the control shaft and holds the anchor rotatably about the second axis;
A second shaft hole that is inserted through the control shaft and that holds the control block rotatably about the second axis, and a second frame connected to the first frame; ,
have,
The brake caliper according to claim 1 or 2, wherein the brake caliper is provided. In the first frame, a first sliding groove for holding the first sliding member is recessed,
The second frame is provided with a second sliding groove for holding the second sliding member,
The brake caliper according to claim 3. The first frame is further formed with a first pinhole that is opened from the first sliding groove so as to extend substantially parallel to the second axis,
The second frame is further formed with a second pinhole that is opened from the second sliding groove so as to extend substantially parallel to the second axis,
The first sliding member extends to be inserted into the first pinhole, and is held by the first pinhole so as to be slidable substantially parallel to the second axis. Have
The second sliding member extends to be inserted into the second pinhole, and is held by the second pinhole so as to be slidable substantially parallel to the second axis. have,
The brake caliper according to claim 4. The interlock mechanism is further attached to the control shaft, and further includes a compression coil spring that biases the first sliding member and the second sliding member apart from each other.
The first frame is provided with a plurality of first cylinder bores opening toward the second frame side,
The second frame is provided with a plurality of second cylinder bores opening toward the first frame side,
The brake caliper
A first piston connected to the first brake pad and installed in each of the first cylinder bores so as to be slidable substantially parallel to the second axis;
A second piston connected to the second brake pad and installed in each of the second cylinder bores so as to be slidable substantially parallel to the second axis;
The brake caliper according to any one of claims 3 to 5, further comprising:
